The Vought F-8 Crusader (originally F8U) is a single-engine, supersonic, carrier-based air superiority jet aircraft[2] built by Vought for the United States Navy and United States Marine Corps (replacing the Vought F7U Cutlass), and for the French Navy. The first F-8 prototype was ready for flight in February 1955. The F-8 served principally in the Vietnam War. The Crusader was the last American fighter with guns as the primary weapon, earning it the title "The Last of the Gunfighters".
The RF-8 Crusader was a photo-reconnaissance development and operated longer in U.S. service than any of the fighter versions. RF-8s played a crucial role in the Cuban Missile Crisis, providing essential low-level photographs impossible to acquire by other means. United States Navy Reserve units continued to operate the RF-8 until 1987...
In September 1952, the United States Navy announced a requirement for a new fighter. It was to have a top speed of Mach 1.2 at 30,000 ft (9,144.0 m) with a climb rate of 25,000 ft/min (127.0 m/s), and a landing speed of no more than 100 mph (160 km/h). Korean War experience had demonstrated that 0.50 inch (12.7 mm) machine guns were no longer sufficient and as a result the new fighter was to carry a 20 mm (0.79 in) cannon...
The Crusader was powered by a Pratt and Whitney J57 turbojet engine. The engine was equipped with an afterburner that, unlike on later engines, was either fully lit, or off (i.e. it did not have "zones"). The engine produced 16,000 lb of thrust static sea level unducted in the initial -44 application, not enough to allow the F-8 to sustain vertical in clean configuration, especially as thrust falls off with installation, subsonic speed, and altitude. The Crusader was the first jet fighter in US service to reach 1,000 mph; U.S. Navy pilot R.W. Windsor reached 1,015 mph on a flight in 1956.
The most innovative aspect of the design was the variable-incidence wing which pivoted by 7° out of the fuselage on takeoff and landing (not to be confused with variable-sweep wing). This allowed a greater angle of attack, increasing lift without compromising forward visibility.[3][4] This innovation helped the F-8's development team win the Collier Trophy in 1956.[6] Simultaneously, the lift was augmented by leading-edge flaps drooping by 25° and inboard flaps extending to 30°. The rest of the aircraft took advantage of contemporary aerodynamic innovations with area-ruled fuselage, all-moving stabilators, dog-tooth notching at the wing folds for improved yaw stability, and liberal use of titanium in the airframe. The armament, as specified by the Navy, consisted primarily of four 20 mm (.79 in) autocannons; the Crusader happened to be the last U.S. fighter designed with guns as its primary weapon. They were supplemented with a retractable tray with 32 unguided Mk 4/Mk 40 Folding-Fin Aerial Rocket (Mighty Mouse FFARs), and cheek pylons for two guided AIM-9 Sidewinder air-to-air missiles. In practice, AIM-9 Sidewinder missiles were the F-8's primary weapon; the 20mm guns were "generally unreliable." Moreover, it achieved nearly all of its kills with Sidewinders. Vought also presented a tactical reconnaissance version of the aircraft called the V-392.
Major competition came from the Grumman F-11 Tiger, the upgraded twin-engine McDonnell F3H Demon (which would eventually become the McDonnell Douglas F-4 Phantom II), and lastly, the North American F-100 Super Sabre hastily adapted to carrier use and dubbed the "Super Fury".
In May 1953, the Vought design was declared a winner and in June, Vought received an order for three XF8U-1 prototypes (after adoption of the unified designation system in September 1962, the F8U became the F-8). The first prototype flew on 25 March 1955 with John Konrad at the controls. The aircraft exceeded the speed of sound during its maiden flight. The development was so trouble-free that the second prototype, along with the first production F8U-1, flew on the same day, 30 September 1955. On 4 April 1956, the F8U-1 performed its first catapult launch from Forrestal....

https://en.wikipedia.org/wiki/Tan_Son_Nhut_Air_Base
Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/
Tan Son Nhut Air Base (Vietnamese: Căn cứ không quân Tân Sơn Nhứt) (1955–1975) was a Republic of Vietnam Air Force (RVNAF) facility. It was located near the city of Saigon in southern Vietnam. The United States used it as a major base during the Vietnam War (1959–1975), stationing Army, Air Force, Navy, and Marine units there. Following the Fall of Saigon, it was taken over as a Vietnam People's Air Force (VPAF) facility and remains in use today.
Tan Son Nhat International Airport, (IATA: SGN, ICAO: VVTS) has been a major Vietnamese civil airport since the 1920s...
Early history
Tan Son Nhat Airport was built by the French in the 1930s when the French Colonial government of Indochina constructed a small unpaved airport, known as Tan Son Nhat Airfield, in the village of Tan Son Nhat to serve as Saigon's commercial airport. Flights to and from France, as well as within Southeast Asia were available prior to World War II. During World War II, the Imperial Japanese Army used Tan Son Nhat as a transport base. When Japan surrendered in August 1945, the French Air Force flew a contingent of 150 troops into Tan Son Nhat.
After World War II, Tân Sơn Nhất served domestic as well as international flights from Saigon.
In mid-1956 construction of a 7,200-foot (2,200 m) runway was completed and the International Cooperation Administration soon started work on a 10,000-foot (3,000 m) concrete runway. The airfield was run by the South Vietnamese Department of Civil Aviation with the RVNAF as a tenant located on the southwest of the airfield.
In 1961, the government of the Republic of Vietnam requested the U.S. Military Assistance Advisory Group (MAAG) to plan for expansion of the Tan Son Nhut airport. A taxiway parallel to the original runway had just been completed by the E.V. Lane company for the U.S. Operations Mission, but parking aprons and connections to the taxiways were required. Under the direction of the U.S. Navy Officer in Charge of Construction RVN, these items were constructed by the American construction company RMK-BRJ in 1962. RMK-BRJ also constructed an air-control radar station in 1962, and the passenger and freight terminals in 1963. In 1967, RMK-BRJ constructed the second 10,000-foot concrete runway...
In 1953, Tan Son Nhut started being used as a military air base for the fledgling RVNAF, and in 1956 the headquarters were moved from the center of Saigon to Tan Son Nhut. But even before that time, French and Vietnamese military aircraft were in evidence at Tan Son Nhut.
On 1 July 1955, the RVNAF 1st Transport Squadron equipped with C-47 Skytrains was established at the base. The RVNAF also had a special missions squadron at the base equipped with 3 C-47s, 3 C-45s and 1 L-26. The 1st Transport Squadron would be renamed the 413rd Air Transport Squadron in January 1963.
In June 1956 the 2nd Transport Squadron equipped with C-47s was established at the base and the RVNAF established its headquarters there. It would be renamed the 415th Air Transport Squadron in January 1963.
In November 1956, by agreement with the South Vietnamese government, the USAF assumed some training and administrative roles of the RVNAF. A full handover of training responsibility took place on 1 June 1957 when the French training contracts expired...
The base was adjacent to the headquarters of the Joint General Staff of South Vietnam, and was a key venue in various military coups, particularly the 1963 coup that deposed the nation's first President Ngô Đình Diệm. The plotters invited loyalist officers to a routine lunch meeting at JGS and captured them in the afternoon of 1 November 1963. The most notable was Colonel Lê Quang Tung, loyalist commander of the ARVN Special Forces, which was effectively a private Ngô family army, and his brother and deputy, Le Quảng Trịeu. Later, Captain Nguyễn Văn Nhung, bodyguard of coup leader General Dương Văn Minh, shot the brothers on the edge of the base...

https://en.wikipedia.org/wiki/Molten-Salt_Reactor_Experiment
Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/
The Molten-Salt Reactor Experiment (MSRE) was an experimental molten salt reactor at the Oak Ridge National Laboratory (ORNL) researching this technology through the 1960s; constructed by 1964, it went critical in 1965 and was operated until 1969.
The MSRE was a 7.4 MWth test reactor simulating the neutronic "kernel" of a type of inherently safer epithermal thorium breeder reactor called the liquid fluoride thorium reactor. It primarily used two fuels: first uranium-235 and later uranium-233. The latter 233UF4 was the result of breeding from thorium in other reactors. Since this was an engineering test, the large, expensive breeding blanket of thorium salt was omitted in favor of neutron measurements.
In the MSRE, the heat from the reactor core was shed via a cooling system using air blown over radiators. It is thought similar reactors could power high-efficiency heat engines such as closed-cycle gas turbines.
The MSRE's piping, core vat and structural components were made from Hastelloy-N and its moderator was a pyrolytic graphite core. The fuel for the MSRE was LiF-BeF2-ZrF4-UF4 (65-29-5-1), the graphite core moderated it, and its secondary coolant was FLiBe (2LiF-BeF2), it operated as hot as 650 °C and operated for the equivalent of about 1.5 years of full power operation.
The result promised to be a simple, reliable reactor. The purpose of the Molten-Salt Reactor Experiment was to demonstrate that some key features of the proposed molten-salt power reactors could be embodied in a practical reactor that could be operated safely and reliably and be maintained without excessive difficulty. For simplicity, it was to be a fairly small, one-fluid (i.e. non-breeding) reactor operating at 10 MWth or less, with heat rejection to the air via a secondary (fuel-free) salt...
The MSRE operated for 5 years. The salt was loaded in 1964 and nuclear operation ended in December 1969, and all the objectives of the experiment were achieved during this period.
Checkout and prenuclear tests included 1,000 hours of circulation of flush salt and fuel carrier salt. Nuclear testing of the MSRE began in June 1965, with the addition of enriched 235U as UF4-LiF eutectic to the carrier salt to make the reactor critical. After zero-power experiments to measure rod worth and reactivity coefficients, the reactor was shut down and final preparations made for power operation. Power ascension was delayed when vapors from oil that had leaked into the fuel pump were polymerized by the radioactive offgas and plugged gas filters and valves. Maximum power, which was limited to 7.4 MW(t) by the capability of the heat-rejection system, was reached in May 1966.
After two months of high-power operation, the reactor was down for three months because of the failure of one of the main cooling blowers. Some further delays were encountered because of offgas line plugging, but by the end of 1966 most of the startup problems were behind. During the next 15 months, the reactor was critical 80% of the time, with runs of 1, 3, and 6 months that were uninterrupted by a fuel drain. By March 1968, the original objectives of the MSRE had been accomplished, and nuclear operation with 235U was concluded.
By this time, ample 233U had become available, so the MSRE program was extended to include substitution of 233U for the uranium in the fuel salt, and operation to observe the new nuclear characteristics. Using the on-site processing equipment the flush salt and fuel salt were fluorinated to recover the uranium in them as UF6. 233UF4-LiF eutectic was then added to the carrier salt, and in October 1968, the MSRE became the world's first reactor to operate on 233U.
The 233U zero-power experiments and dynamics tests confirmed the predicted neutronic characteristics. An unexpected consequence of processing the salt was that its physical properties were altered slightly so that more than the usual amount of gas was entrained from the fuel pump into the circulating loop. The circulating gas and the power fluctuations that accompanied it were eliminated by operating the fuel pump at slightly lower speed. Operation at high power for several months permitted accurate measurement of the capture-to-fission ratio, for 233U in this reactor, completing the objectives of the 233U operation...

The Waco CG-4 was the most widely used American troop/cargo military glider of World War II. It was designated the CG-4A by the United States Army Air Forces, and named Hadrian (after the Roman emperor) in British military service.
Designed by the Waco Aircraft Company, flight testing began in May 1942, and eventually more than 13,900 CG-4As were delivered...
Design and development
The CG-4A was constructed of fabric-covered wood and metal and was crewed by a pilot and copilot. It had two fixed mainwheels and a tailwheel.
The CG-4A could carry 13 troops and their equipment. Cargo loads could be a 1⁄4-ton truck (i.e. a Jeep), a 75 mm howitzer, or a 1⁄4-ton trailer, loaded through the upward-hinged nose section. C-47s were usually used as tow aircraft. A few C-46 tugs were used during and after Operation Plunder.
The USAAF CG-4A tow line was 11⁄16 inch (17 mm) nylon, 350 feet (107 m) long. The CG-4A pickup line was 15⁄16 inch (24 mm) diameter nylon, but only 225 ft (69 m) long including the doubled loop.
In effort to identify areas where strategic materials could be reduced, a single XCG-4B was built at the Timm Aircraft Corporation using wood for the main structure.
Production
From 1942 to 1945, the Ford Motor Company's plant in Kingsford, Michigan, built 4,190 Model CG-4A gliders for use in combat operations during World War II. The Kingsford plant built more CG-4A gliders than any other company in the nation at much less cost than other manufacturers. The other primary builders of the Model CG-4A gliders were located in Troy, Ohio; Greenville, Michigan; Astoria, New York; Kansas City, Missouri and St. Paul, Minnesota.
The 16 companies that were prime contractors for manufacturing the CG-4A were:
Babcock Aircraft Company of DeLand, Florida (60 at $51,000 each)
Cessna Aircraft Company of Wichita, Kansas (750) The entire order was subcontracted to Boeing Aircraft Company's new Wichita plant.
Commonwealth Aircraft of Kansas City (1,470)
Ford Motor Company of Kingsford, Michigan (4,190 units at $14,891 each)
G&A Aircraft of Willow Grove, PA (627)
General Aircraft Corporation of Astoria, L.I.,NY (1,112)
Gibson Refrigerator of Greenville, Michigan (1,078)
Laister-Kauffman Corporation of St. Louis, Missouri (310)
National Aircraft Corp. of Elwood, IN (one, at an astronomical $1,741,809)
Northwestern Aeronautical Corporation of Minneapolis (1,510)
Pratt-Read of Deep River, Connecticut (956)
Ridgefield Manufacturing Company of Ridgeville, New Jersey (156)
Robertson Aircraft Corporation of St. Louis (170)
Timm Aircraft Company of Van Nuys, California (434)
Waco Aircraft Company of Troy (1074 [999] units at $19,367 each)

The President's Council on Sports, Fitness and Nutrition (PCSFN) is an American government organization that aims to "promote, encourage and motivate Americans of all ages to become physically active and participate in sports". It is part of the Office of Public Health and Science, an agency of the United States Department of Health and Human Services. Prior to June 2010, it was called the President's Council on Physical Fitness and Sports...
History
During the 1940s, the American Medical Association and the National Committee on Physical Fitness had a joint committee encouraging physical fitness.
The President's Council on Youth Fitness was founded on July 16, 1956, to encourage American children.
In 1963, President Kennedy changed the council's name to President's Council on Physical Fitness to reflect its role to serve all Americans.
In 1966, President Lyndon B. Johnson created the Presidential Physical Fitness Award, the name of which was later changed to President's Challenge Youth Physical Fitness Awards Program. In 1968, the council's name was changed to President's Council on Physical Fitness and Sports to emphasize the importance of sports in life.
In 1972, the Presidential Sports Award Program was created.
In 1983, the United States Congress declared May as National Physical Fitness and Sports Month.
In 1996, the Surgeon General's Report on Physical Activity and Health was released. In 1997, the Council released its report on Physical Activity and Sport in the Lives of Boys.
In June 2010, President Barack Obama renamed the agency the President's Council on Fitness, Sports and Nutrition, with a new emphasis on nutrition as an element of fitness. First Lady Michelle Obama announced the new commission's goal "to end the epidemic of childhood obesity in a generation" and also announced that the president had named, as the new co-chairs of the council, New Orleans Saints quarterback Drew Brees and former Olympic gymnast Dominique Dawes.
On January 11, 2012, operators of the website for participants of the Challenge and Active Lifestyle programs learned that the site had been hacked, resulting in the release of personal information of the participants. The President's Challenge site displayed a notice that it was down for "Site Maintenance – We're taking a little breather." On January 20, 2012, the site was modified to explain the hacking. On January 27, 2012, The President's Challenge sent out emails to its participants saying that the website was functional as of January 24, 2012, and asked participants to reset their user passwords...

https://en.wikipedia.org/wiki/M61_Vulcan
Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/
The M61 Vulcan is a hydraulically, electrically or pneumatically driven, six-barrel, air-cooled, electrically fired Gatling-style rotary cannon which fires 20 mm rounds at an extremely high rate (typically 6,000 rounds per minute). The M61 and its derivatives have been the principal cannon armament of United States military fixed-wing aircraft for sixty years.
The M61 was originally produced by General Electric. After several mergers and acquisitions, it is currently produced by General Dynamics...
The idea of powering a Gatling gun from an external electric power source was not a novel idea at the end of World War II, as Richard Jordan Gatling himself had done just that with a patent he filed in 1893, with the similar, but powered either by the aircraft engine or an electric motor, 12-barreled Fokker-Leimberger aircraft rotary machine gun under development during World War I by the German Empire.
In 1946, the Army issued General Electric a contract for "Project Vulcan", a six-barrel weapon capable of firing 7,200 rounds per minute (rpm). Although European designers were moving towards heavier 30 mm weapons for better hitting power, the U.S. initially concentrated on a powerful 0.60-inch (15 mm) cartridge designed for a pre-war anti-tank rifle, expecting that the cartridge's high muzzle velocity would be beneficial for improving hit ratios on high speed targets. The first GE prototypes of the 0.60-inch (15 mm) caliber T45 were ground-fired in 1949; it achieved 2,500 rpm, which was increased to 4,000 rpm by 1950. By the early 1950s, the USAF decided that high velocity alone might not be sufficient to ensure target destruction and tested 20 mm and 27 mm alternatives based on the 0.60-inch (15 mm) caliber cartridge. These variants of the T45 were known as the T171 and T150 respectively and were first tested in 1952. Eventually, the standard 20×102 mm cartridge was determined to have the desired balance of projectile/explosive mass and muzzle velocity, resulting in an optimum balance of range, accuracy and kinetic energy on target.
The development of the Lockheed F-104 Starfighter revealed that the T171 Vulcan (later redesignated M61) suffered problems with its linked ammunition, being prone to misfeed and presenting a foreign object damage (FOD) hazard with discarded links. A linkless ammunition feed system was developed for the upgraded M61A1, which subsequently became the standard cannon armament of U.S. fighters.
In 1993, General Electric sold its aerospace division, including GE Armament Systems along with the design and production tooling for the M61 and GE's other rotary cannon, to Martin Marietta. After Martin's merger with Lockheed, the rotary cannon became the responsibility of Lockheed Martin Armament Systems. Lockheed Martin Armament Systems was later acquired by General Dynamics, who currently produce the M61 and its variants...

https://en.wikipedia.org/wiki/Kraft_paper
Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/
Kraft paper or kraft is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process.
Sack kraft paper, or just sack paper, is a porous kraft paper with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability.
Pulp produced by the kraft process is stronger than that made by other pulping processes; acidic sulfite processes degrade cellulose more, leading to weaker fibers, and mechanical pulping processes leave most of the lignin with the fibers, whereas kraft pulping removes most of the lignin present originally in the wood. Low lignin is important to the resulting strength of the paper, as the hydrophobic nature of lignin interferes with the formation of the hydrogen bonds between cellulose (and hemicellulose) in the fibers.
Kraft pulp is darker than other wood pulps, but it can be bleached to make very white pulp. Fully bleached kraft pulp is used to make high quality paper where strength, whiteness, and resistance to yellowing are important...
Wood pulp for sack paper is made from softwood by the kraft process. The long fibers provide the paper its strength and wet strength chemicals are added to even further improve the strength. Both white and brown grades are made. Sack paper is then produced on a paper machine from the wood pulp. The paper is microcrepped to give porosity and elasticity. Microcrepping is done by drying with loose draws allowing it to shrink. This causes the paper to elongate 4% in the machine direction and 10% in the cross direction without breaking. Machine direction elongation can be further improved by pressing between very elastic cylinders causing more microcrepping. The paper may be coated with polyethylene (PE) to ensure an effective barrier against moisture, grease and bacteria, although recyclability is hindered. Zein coatings are also water resistant but allow better recyclability.
A paper sack can be made of several layers of sack paper depending on the toughness needed.
Kraft paper is produced on paper machines with moderate machine speeds. The raw material is normally softwood pulp from the kraft process.
Maintaining a high effective sulfur ratio or sulfidity is important for the highest possible strength using the kraft process.
The kraft process can use a wider range of fiber sources than most other pulping processes. All types of wood, including very resinous types like southern pine, and non-wood species like bamboo and kenaf can be used in the kraft process...
https://en.wikipedia.org/wiki/Union_Camp_Corporation
Union Camp Corporation was an American pulp and paper company and a private owner of timberland in the United States. In 1999 it was acquired by International Paper...
Union Camp came about through the merger of the Union Bag and Paper Company and the Camp Manufacturing Company. Each of these family-owned companies had unique histories that led to the ultimate success of Union Camp until it was acquired by International paper...
The Union Bag and Paper Company's history dates back to 1881 where it began as the Union Paper Bag Machine Company in Bethlehem Pennsylvania under the Calder family. In the late 1920s, partially due to concerns about the labor union movement in the north, the company built a major mill (the largest in the world at the time and for many years) in Savannah, GA. This mill, and local politics, were the subject of Ralph Nader's book, The Water Lords. The company had a major impact on Savannah politics, but was highly respected in the area as having kept Savannah from many of the severe effects of the Great Depression...

https://en.wikipedia.org/wiki/Portsmouth_Gaseous_Diffusion_Plant

The Portsmouth Gaseous Diffusion Plant is a facility located in Scioto Township, Pike County, Ohio, just south of Piketon, Ohio that previously produced enriched uranium, including weapons-grade uranium, for the United States Atomic Energy program and U.S. nuclear weapons program. The plant is in shutdown status and is in preparation for decontamination and decommissioning (D&D), with some facilities overseen by the United States Enrichment Corporation, a subsidiary of USEC Incorporated, a publicly traded corporation (NYSE: USU). The D&D work on the older facilities to prepare the site for future use is expected to continue through 2024 and is being conducted by Fluor-B&W Portsmouth LLC.
The Portsmouth plant, so named because of its proximity to the city of Portsmouth, Ohio, was one of three gaseous diffusion plants in the United States, alongside the K-25 plant in Oak Ridge, Tennessee and the Paducah Gaseous Diffusion Plant in Kentucky. The plant was constructed from 1952–1956, with the first enrichment cells going online in 1954. The plant was operated by the Goodyear Tire and Rubber Company from its startup to 1986, when the contract was taken over by Martin Marietta. In 1993, the USEC took overall responsibility for the Paducah and Portsmouth enrichment plants, continuing the operating contract with Martin Marietta. In 1995, the operator became Lockheed Martin with the merger of Martin Marietta and Lockheed. In May 2001, the Piketon plant ceased operations and was placed in cold standby. In 2006, the site work shifted into cold shutdown transition in preparation for future Decontamination and Decommissioning (D&D).
The former gaseous diffusion plant covers 640 acres (260 ha) of the 3,777-acre (1,528 ha) site. The largest buildings, the process buildings, have a combined length of approximately one and a half miles (2.4 km), and cover about 93 acres (38 ha) and contain 10 million square feet (0.93 km2) of space. In use, the plant consumed a peak electrical demand of 2,100 megawatts.
A commercial centrifuge plant at the Portsmouth site began construction in May 2007 for the production of commercial nuclear fuel for power reactors. Once completed, the commercial plant will use approximately 11,500 centrifuge machines to generate 3.8 million separative work units (SWU) a year...
Operations began in 1954 while construction was ongoing with the plant coming fully online in early 1956, several months ahead of schedule.
The primary mode of enrichment was the gaseous diffusion of uranium hexafluoride to separate the lighter fissile isotope, U-235, from the heavier non-fissile isotope, U-238. The plant initially produced material for the U.S. nuclear weapons program. In the mid-1960s, the plant converted to fuel production for commercial nuclear power plants. Portsmouth took material from Paducah that was enriched to 2.75% U-235 and further enriched it to approximately 4% and 5%.

To support operations, the AEC entered into the largest contract for a single customer in the history of the electrical utility industry for power at that time. Power usage was equal to the all-time high voltage requirements in the United States, more than 2,000 megawatts - 18 billion kilowatt hours yearly. To handle the power requirements, two large switchyards were constructed on site. Two large steam electric generating stations were built to supply power at Clifty Creek in Madison, Indiana and Kyger Creek in Gallipolis, Ohio. At the time, they were the largest power plants built by private industry as well as the most efficient, producing 1 kilowatt hour of electricity for 0.7 pounds (0.32 kg) of coal. The power plants used 7.5 million short tons (6.8 million t) of coal annually to support operations...

Grooming (also called preening) is the art of cleaning and maintaining parts of the body. It is a species-typical behavior...
In animals
Individual animals regularly clean themselves and put their fur, feathers or other skin coverings in good order. This activity is known as personal grooming, a form of hygiene. Extracting foreign objects such as insects, leaves, dirt, twigs and parasites is a form of grooming. Among animals, birds spend considerable time preening their feathers. This is done to remove ectoparasites, keep the feathers in good aerodynamic condition, and waterproof them. To do that, they use the preen oil secreted by the uropygial gland, the dust of down feathers, or other means such as dust-bathing or anting. During oil spills, animal conservationists that rescue penguins sometimes dress them in knitted sweaters to stop them from preening and thereby ingesting the mineral oil, which is poisonous. Monkeys may also pick out nits from their fur or scratch their rears to keep themselves clean. Cats are well known for their extensive grooming. Cats groom so often that they often produce hairballs from the fur they ingest. Many mammal species also groom their genitals after copulation.
Grooming as a social activity
Many social animals adapt preening and grooming behaviors for other social purposes such as bonding and the strengthening of social structures. Grooming plays a particularly important role in forming social bonds in many primate species, such as chacma baboons and wedge-capped capuchins...
https://en.wikipedia.org/wiki/Social_grooming
Social grooming is a behavior in which social animals, including humans, clean or maintain one another's body or appearance. A related term, allogrooming, indicates social grooming between members of the same species. Grooming is a major social activity, and a means by which animals who live in close proximity may bond and reinforce social structures, family links, and build companionships. Social grooming is also used as a means of conflict resolution, maternal behavior and reconciliation in some species. Mutual grooming typically describes the act of grooming between two individuals, often as a part of social grooming, pair bonding, or a precoital activity...
Evolutionary advantages
There are a variety of proposed mechanisms by which social grooming behavior has been hypothesized to increase fitness. These evolutionary advantages may come in the form of health benefits including reduced disease transmission and reduced stress levels, maintaining social structure, and direct improvement of fitness as a measure of survival.
Health benefits
It is often argued as to whether the overarching importance of social grooming is to boost an organism's health and hygiene or whether the social side of social grooming plays an equally or more important role. Traditionally, it is thought that the primary function of social grooming is the upkeep of an animal's hygiene. Evidence to support this statement involves the fact that allogrooming concentrates on body parts that are inaccessible by autogrooming and that the amount of time spent allogrooming regions did not vary significantly even if the body part had a more important social or communicatory function.
Social grooming behaviour has been shown to elicit an array of health benefits in a variety of species. For example, group member connection has the potential to mitigate the potentially harmful effects of stressors. In macaques, social grooming has been proven to reduce heart rate. Social affiliation during a mild stressor was shown to correlate with lower levels of mammary tumor development and longer lifespan in rats, while lack of this affiliation was demonstrated to be a major risk factor. Grooming has also been shown to play an integral role in reducing tick load in wild baboons...

The Battle of Midway is a 1942 American short documentary film directed by John Ford. It is a montage of color footage of the Battle of Midway with voice overs of various narrators, including Johnny Governali, Donald Crisp, Henry Fonda, and Jane Darwell...
Plot
The film begins with a male narrator (Donald Crisp) explaining where Midway Island is and its strategic importance. About five minutes into the film the format changes somewhat, with more leisurely pictures of the G.I.s at work on the island, and then a female voice over. The female voice over (Jane Darwell) takes the personality of a middle aged woman from Springfield, Ohio, who is a mother-type figure pointing out how she recognizes a boy from her home town. The boy is Army Air Force pilot William E. "Junior" Kinney. Then stock footage of the Kinney family back home is introduced.
Abruptly the narrative (spoken by Henry Fonda) turns to the battle itself with approximately five minutes dedicated to the defense of the island, the naval battle, and the aftermath. At the end the various known Japanese losses are shown (four aircraft carriers, as well as battleships, aircraft, and men) and then brushed over with red or black paint.
Production notes
When the United States Navy sent director John Ford to Midway Island in 1942, he believed that the military wanted him to make a documentary on life at a small, isolated military base, and filmed casual footage of the sailors and marines there working and having fun. Two days before the battle, he learned that the Japanese planned to attack the base and that it was preparing to defend itself. Ford's handheld, 16mm footage of the battle was captured totally impromptu. He had been in transit on the island, roused from his bunk by the sounds of the battle, and started filming. Ford was wounded by enemy fire while filming the battle. Acclaimed as a hero when he returned home because of the footage and the minor wound, Ford decades later incorrectly claimed to Peter Bogdanovich that he was the only cameraman; however, Jack Mackenzie Jr. and Kenneth Pier assisted Ford in filming.
Ford was worried that military censors would prevent the footage from being shown in public. After returning to Los Angeles, he gave the footage to Robert Parrish, who had worked with him on How Green Was My Valley, to edit in secret. Ford spliced in footage of James Roosevelt, President Franklin D. Roosevelt's son and a Marine Corps officer; when the president saw the film in the White House, he told William Leahy: "I want every mother in America to see this film", thus protecting Ford from censorship. Parrish wrote an in-depth account of the making of The Battle of Midway in his autobiography, Growing Up in Hollywood (1976). The film runs for 18 minutes, was distributed by 20th Century Fox, and was one of four winners of the inaugural, 1942 Academy Award for Best Documentary.
Seeing men he had met and filmed die horrified Ford, who said, "I am really a coward" compared to those who fought. He had spent time with Torpedo Squadron 8, and 29 of 30 men of the unit died or were missing after the battle. Ford assembled the footage he had taken of the squadron into an eight-minute film, adding titles praising the squadron for having "written the most brilliant pages in the glowing history of our Naval Air Forces" and identifying each man as he appeared. He printed the result, Torpedo Squadron 8, to 8mm film suitable for home projectors and sent copies to the men's families.

...With Lieutenant General Matthew Ridgway assuming the command of the US Eighth Army on 26 December, the PVA and the KPA launched their Third Phase Offensive (also known as the "Chinese New Year's Offensive") on New Year's Eve of 1950/51... The offensive overwhelmed UN forces, allowing the PVA and KPA to capture Seoul for the second time on 4 January 1951. Following this, the CPV party committee issued orders regarding tasks during rest and reorganization on 8 January 1951, outlining Chinese war goals. The orders read: "the central issue is for the whole party and army to overcome difficulties ... to improve tactics and skills. When the next campaign starts ... we will annihilate all enemies and liberate all Korea." In his telegram to Peng on 14 January, Mao stressed the importance of preparing for "the last battle" in the spring in order to "fundamentally resolve the [Korean] issue."
These setbacks prompted General MacArthur to consider using nuclear weapons against the Chinese or North Korean interiors, with the intention that radioactive fallout zones would interrupt the Chinese supply chains. However, upon the arrival of the charismatic General Ridgway, the esprit de corps of the bloodied Eighth Army immediately began to revive.
UN forces retreated to Suwon in the west, Wonju in the center, and the territory north of Samcheok in the east, where the battlefront stabilized and held. The PVA had outrun its logistics capability and thus were unable to press on beyond Seoul as food, ammunition, and matériel were carried nightly, on foot and bicycle, from the border at the Yalu River to the three battle lines. In late January, upon finding that the PVA had abandoned their battle lines, General Ridgway ordered a reconnaissance-in-force, which became Operation Thunderbolt (25 January 1951). A full-scale advance followed, which fully exploited the UN's air superiority, concluding with the UN forces reaching the Han River and recapturing Wonju.
Following the failure of ceasefire negotiations in January, the United Nations General Assembly passed Resolution 498 on 1 February, condemning the PRC as an aggressor, and called upon its forces to withdraw from Korea.
In early February, the ROK 11th Division ran the operation to destroy the guerrillas and their sympathizer citizens in Southern Korea. During the operation, the division and police conducted the Geochang massacre and Sancheong-Hamyang massacre. In mid-February, the PVA counterattacked with the Fourth Phase Offensive and achieved initial victory at Hoengseong. But the offensive was soon blunted by US IX Corps at Chipyong-ni in the center. The US 23rd Regimental Combat Team and the French Battalion fought a short but desperate battle that broke the attack's momentum. The battle is sometimes known as the "Gettysburg of the Korean War": 5,600 South Korean, U.S., and French troops were surrounded on all sides by 25,000 PVA. UN forces had previously retreated in the face of large PVA/KPA forces instead of getting cut off, but this time they stood and fought, and won...
In the last two weeks of February 1951, Operation Thunderbolt was followed by Operation Killer, carried out by the revitalized Eighth Army. It was a full-scale, battlefront-length attack staged for maximum exploitation of firepower to kill as many KPA and PVA troops as possible. Operation Killer concluded with US I Corps re-occupying the territory south of the Han River, and IX Corps capturing Hoengseong. On 7 March 1951, the Eighth Army attacked with Operation Ripper, expelling the PVA and the KPA from Seoul on 14 March 1951. This was the fourth and final conquest of the city in a year's time, leaving it a ruin; the 1.5 million pre-war population was down to 200,000, and people were suffering from severe food shortages...

The Great Smoky Mountains are a mountain range rising along the Tennessee–North Carolina border in the southeastern United States. They are a subrange of the Appalachian Mountains, and form part of the Blue Ridge Physiographic Province. The range is sometimes called the Smoky Mountains and the name is commonly shortened to the Smokies. The Great Smokies are best known as the home of the Great Smoky Mountains National Park, which protects most of the range. The park was established in 1934, and, with over 11 million visits per year, it is the most visited national park in the United States.
The Great Smokies are part of an International Biosphere Reserve. The range is home to an estimated 187,000 acres (76,000 ha) of old growth forest, constituting the largest such stand east of the Mississippi River. The cove hardwood forests in the range's lower elevations are among the most diverse ecosystems in North America, and the Southern Appalachian spruce-fir forest that coats the range's upper elevations is the largest of its kind. The Great Smokies are also home to the densest black bear population in the Eastern United States and the most diverse salamander population outside of the tropics.
Along with the Biosphere reserve, the Great Smokies have been designated a UNESCO World Heritage Site. The U.S. National Park Service preserves and maintains 78 structures within the national park that were once part of the numerous small Appalachian communities scattered throughout the range's river valleys and coves. The park contains five historic districts and nine individual listings on the National Register of Historic Places.
The name "Smoky" comes from the natural fog that often hangs over the range and presents as large smoke plumes from a distance. This fog is caused by the vegetation exhaling volatile organic compounds, chemicals that have a high vapor pressure and easily form vapors at normal temperature and pressure...
European explorers and settlers began arriving in Western North Carolina and East Tennessee in the mid-18th century. The influx of settlers at the end of the French and Indian War brought conflict with the Cherokee, who still held legal title to much of the land. When the Cherokee aligned themselves with the British at the outbreak of the American Revolution in 1776, American forces launched an invasion of Cherokee territory.
The Middle towns, including Kittuwa, were burned by General Griffith Rutherford, and several of the Overhill towns were burned by John Sevier. By 1805, the Cherokee had ceded control of the Great Smokies to the U.S. government. Although much of the tribe was forced west along the Trail of Tears in 1838, a few—largely through the efforts of William Holland Thomas—managed to retain their land on the Qualla Boundary and today comprise the Eastern Band of Cherokee Indians.
In the 1780s, several frontier outposts had been established along the outskirts of the Smokies, namely Whitson's Fort in what is now Cosby and Wear's Fort in what is now Pigeon Forge. Permanent settlers began arriving in these areas in the 1790s. In 1801, the Whaley brothers, William and John, moved from North Carolina to become the first settlers in what is now the Greenbrier section of the park.
In 1802, Edgefield, South Carolina resident William Ogle (1751–1803) arrived in White Oak Flats where he cut and prepared logs for cabin construction...
Cades Cove was settled largely by families who had purchased lots from land speculator William "Fighting Billy" Tipton. The first of these settlers, John and Lucretia Oliver, arrived in 1818. Two Cades Cove settlers, Moses and Patience Proctor, crossed over to the North Carolina side of the Smokies in 1836 to become the first Euro-American settlers in the Hazel Creek area. The Cataloochee area was first settled by the Caldwell family, who migrated to the valley in 1834.
Like most of Southern Appalachia, the early 19th-century economy of the Smokies relied on subsistence agriculture...

The Cheyenne Mountain Complex is a Space Force installation and defensive bunker located in unincorporated El Paso County, Colorado, next to the city of Colorado Springs, at the Cheyenne Mountain Air Force Station,[a] which hosts the activities of several tenant units. Also located in Colorado Springs is Peterson Air Force Base, where the North American Aerospace Defense Command (NORAD) and United States Northern Command (USNORTHCOM) headquarters are now located...
Formerly the center for the United States Space Command and NORAD, the Complex monitored the air space of Canada and the United States for missiles, space systems, and foreign aircraft through its worldwide early-warning system. Since 2008, NORAD and the United States Space Command have been based at Peterson Air Force Base and the complex, re-designated as an air force station, is used for flight crew training and as a back-up command center if required.
The military complex has included, in the past, many units of NORAD, U.S. Space Command, Aerospace Defense Command (ADCOM), Air Force Systems Command, Air Weather Service, and Federal Emergency Management (FEMA). The complex's communication center is also used by the nearby U.S. Civil Defense Warning Center...
The complex was built under 2,000 feet (610 m) of granite on 2 hectares (5 acres). Fifteen three-story buildings are protected from movement, e.g. earthquake or explosion, by a system of giant springs that the buildings sit on and flexible pipe connectors to limit the operational effect of movement. A total of more than 1,000 springs are designed to prevent any of the 15 buildings from shifting more than 1 inch (25 mm). The complex is the only high-altitude Department of Defense facility certified to be able to sustain an electromagnetic pulse (EMP). There is a large quantity of cots for most of the personnel, including suites for high-ranking officers within the bunker. Amenities include a medical facility, store, cafeteria, and fitness centers inside and outside the mountain...
The bunker is built to deflect a 30 megaton nuclear explosion as close as 2 kilometers (1.2 mi). Within a mountain tunnel are sets of 25-ton blast doors and another for the civil engineering department. The doors were built so that they can always be opened when needed. Should a nuclear blast hit the building, they are designed to withstand a blast wave. There is a network of blast valves with unique filters to capture airborne chemical, biological, radiological, and nuclear contaminants...
The Space Defense Center and the Combat Operations Center achieved full operational capability on February 6, 1967. The total cost was $142.4 million. Its systems included a command and control system developed by Burroughs Corporation. The electronics and communications system centralized and automated the instantaneous (one-millionth of a second) evaluation of aerospace surveillance data. The Space Defense Center moved from Ent AFB to the complex in 1965. The NORAD Combat Operations Center was fully operational April 20, 1966 and The Space Defense Command's 1st Aerospace Control Squadron moved to Cheyenne Mountain that month. The following systems or commands became operational between May and October, 1966: The NORAD Attack Warning System, Combat Operations Command, and Delta I computer system, which recorded and monitored every detected space system. By January 4, 1967, the National Civil Defense Warning Center was in the bunker...

https://en.wikipedia.org/wiki/Shoemaking
Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/
Shoemaking is the process of making footwear.
Originally, shoes were made one at a time by hand, often by groups of shoemakers, or cobblers (also known as cordwainers). In the 18th century, dozens or even hundreds of masters, journeymen and apprentices (both men and women) would work together in a shop, dividing up the work into individual tasks. A customer could come into a shop, be individually measured, and return to pick up their new shoes in as little as a day. Everyone needed shoes, and the median price for a pair was about one day’s wages for an average journeyman.
The shoemaking trade flourished in the eighteenth and early nineteenth centuries but began to be affected by industrialization in the later nineteenth century. Traditional handicraft shoemaking has now been largely superseded in volume of shoes produced by industrial mass production of footwear, but not necessarily in quality, attention to detail, or craftsmanship. Today, most shoes are made on a volume basis, rather than a craft basis. A pair of "bespoke" shoes, made in 2020 according to traditional practices, can be sold for thousands of dollars.
Shoemakers may produce a range of footwear items, including shoes, boots, sandals, clogs and moccasins. Such items are generally made of leather, wood, rubber, plastic, jute or other plant material, and often consist of multiple parts for better durability of the sole, stitched to a leather upper part.
Trades that engage in shoemaking have included the cordwainer's and cobbler's trades. The term cobbler was originally used pejoratively to indicate that someone did not know their craft; in the 18th century it became a term for those who repaired shoes but did not know enough to make them...
https://en.wikipedia.org/wiki/Combat_boot
Combat boots are military boots designed to be worn by soldiers during combat or combat training, as opposed to during parades and other ceremonial duties. Modern combat boots are designed to provide a combination of grip, ankle stability, and foot protection suitable for a rugged environment. They are traditionally made of hardened and sometimes waterproofed leather. Today, many combat boots incorporate technologies originating in civilian hiking boots, such as Gore-Tex nylon side panels, which improve ventilation and comfort. They are also often specialized for certain climates and conditions, such as jungle boots, desert boots, and cold weather boots as well as specific uses, such as tanker boots and jump boots...

The history of film technology traces the development of techniques for the recording, construction and presentation of motion pictures. When the film medium came about in the 19th century, there already was a centuries old tradition of screening moving images through shadow play and the magic lantern that were very popular with audiences in many parts of the world. Especially the magic lantern influenced much of the projection technology, exhibition practices and cultural implementation of film. Between 1825 and 1840, the relevant technologies of stroboscopic animation, photography and stereoscopy were introduced. For much of the rest of the century, many engineers and inventors tried to combine all these new technologies and the much older technique of projection to create a complete illusion or a complete documentation of reality. Colour photography was usually included in these ambitions and the introduction of the phonograph seemed to promise the addition of synchronized sound recordings. Between 1887 to 1894, the first successful short cinematographic presentations were established. The biggest popular breakthrough of the technology came in 1895 with the first projected movies that lasted longer than 10 seconds. Initially, motion pictures lasted about 50 seconds, lacked synchronized sound and natural colour, and were mainly exhibited as novelty attractions. During the 20th century, movies grew much longer and the medium quickly developed into one of the most important tools of communication and entertainment. The breakthrough of synchronized sound occurred at the end of the 1920s and that of full color motion picture film in the 1930s (although black and white films remained very common for several decades). By the start of the 21st century, physical film stock was being replaced with digital film technologies at both ends of the production chain by digital image sensors and projectors...
https://en.wikipedia.org/wiki/History_of_film
Although the start of the history of film as an artistic medium is not clearly defined, the commercial, public screening of ten of Lumière brothers' short films in Paris on 28 December 1895 can be regarded as the breakthrough of projected cinematographic motion pictures. There had been earlier cinematographic results and screenings by others, but they lacked either the quality, financial backing, stamina or the luck to find the momentum that propelled the cinématographe Lumière into a worldwide success.
Soon film production companies and studios were established all over the world...
Special effects became a feature in movies since the late 1890s, popularized by Georges Méliès' fantasy films. Many effects were impossible or impractical to perform in theater plays and thus added more magic to the experience of movies.
Technical improvements added length (reaching 60 minutes for a feature film in 1906), synchronized sound recording (mainstream since the end of the 1920s), color (mainstream since the 1930s) and 3D (mainstream in theaters in the early 1950s and since the 2000s). Sound ended the necessity of interruptions of title cards, revolutionized the narrative possibilities for filmmakers, and became an integral part of moviemaking...
Different film genres emerged and enjoyed variable degrees of success over time, with huge differences between for instance horror films (mainstream since the 1890s), newsreels (prevalent in U.S. cinemas between the 1910s and the late 1960s), musicals (mainstream since the late 1920s) and pornographic films (experiencing a Golden Age during the 1970s)...

The history of the United States Marine Corps (USMC) begins with the founding of the Continental Marines on 10 November 1775 to conduct ship-to-ship fighting, provide shipboard security and discipline enforcement, and assist in landing forces. Its mission evolved with changing military doctrine and foreign policy of the United States. Owing to the availability of Marine forces at sea, the United States Marine Corps has served in nearly every conflict in United States history. It attained prominence when its theories and practice of amphibious warfare proved prescient, and ultimately formed a cornerstone of U.S. strategy in the Pacific Theater of World War II. By the early 20th century, the Marine Corps would become one of the dominant theorists and practitioners of amphibious warfare. Its ability to rapidly respond on short notice to expeditionary crises has made and continues to make it an important tool for U.S. foreign policy.
In February 1776, the Continental Marines embarked on their maiden expedition. The Continental Marines were disbanded at the end of the war, along with the Continental Navy. In preparation for the Quasi-War with France, Congress created the United States Navy and the Marine Corps. The Marines' most famous action of this period occurred in the First Barbary War (1801–1805) against the Barbary pirates. In the Mexican–American War (1846–1848), the Marines made their famed assault on Chapultepec Palace, which overlooked Mexico City, their first major expeditionary venture. In the 1850s, the Marines would see service in Panama, and in Asia. During the U.S. Civil War (1861–1865) the Marine Corps played only a minor role after their participation in the Union defeat at the first battle of First Bull Run/Manassas. Their most important task was blockade duty and other ship-board battles, but they were mobilized for a handful of operations as the war progressed. The remainder of the 19th century would be a period of declining strength and introspection about the mission of the Marine Corps. Under Commandant Jacob Zeilin's term (1864–1876), many Marine customs and traditions took shape. During the Spanish–American War (1898), Marines would lead U.S. forces ashore in the Philippines, Cuba, and Puerto Rico, demonstrating their readiness for deployment. Between 1900 and 1916, the Marine Corps continued its record of participation in foreign expeditions, especially in the Caribbean and Central and South America, which included Panama, Cuba, Veracruz, Haiti, Santo Domingo, and Nicaragua.
In World War I, battle-tested, veteran Marines served a central role in the United States' entry into the conflict. Between the world wars, the Marine Corps was headed by Major General John A. Lejeune, another popular commandant. In World War II, the Marines played a central role, under Admiral Nimitz, in the Pacific War, participating in nearly every significant battle. The Corps also saw its peak growth as it expanded from two brigades to two corps with six divisions, and five air wings with 132 squadrons. During the Battle of Iwo Jima, photographer Joe Rosenthal took the famous photo Raising of the Flag on Iwo Jima of five Marines and one naval corpsman raising a U.S. flag on Mount Suribachi. The Korean War (1950–1953) saw the 1st Provisional Marine Brigade holding the line at the Battle of Pusan Perimeter, where Marine helicopters (VMO-6 flying the HO3S1 helicopter) made their combat debut. The Marines also played an important role in the Vietnam War at battles such as Da Nang, Huế, and Khe Sanh. The Marines operated in the northern I Corps regions of South Vietnam and fought both a constant guerilla war against the Viet Cong and an off and on conventional war against North Vietnamese Army regulars. Marines went to Beirut during the 1982 Lebanon War on 24 August. On 23 October 1983, the Marine barracks in Beirut was bombed, causing the highest peacetime losses to the Corps in its history. Marines were also responsible for liberating Kuwait during the Gulf War (1990–1991), as the Army made an attack to the west directly into Iraq. The I Marine Expeditionary Force had a strength of 92,990 making Operation Desert Storm the largest Marine Corps operation in history...

The United States Naval Radiological Defense Laboratory (NRDL) was an early military lab created to study the effects of radiation and nuclear weapons. The facility was based at the Hunter's Point Naval Shipyard in San Francisco, California...
History
The NRDL was formed in 1946 to manage testing, decontamination, and disposition of US Navy ships contaminated by the Operation Crossroads nuclear tests in the Pacific. A number of ships that survived the atomic detonations were towed to Hunter's Point for detailed study and decontamination. Some of the ships were cleaned and sold for scrap. The aircraft carrier USS Independence, which had been heavily damaged and contaminated with nuclear fallout by Operation Crossroads explosions in July 1946, was brought to the NRDL for study. After years of trying in vain to decontaminate the ship enough that it could be safely sold for scrap, the Navy ultimately packed the ship full of nuclear waste and scuttled the radioactive hulk off California near the Farallon Islands in January 1951. The ship's wreck was discovered resting upright under 790 m of water in 2009...
Activities
An article published 2 May 2001 in SF Weekly detailed various aspects of nuclear testing at NRDL from declassified records:
The NRDL often experimented with and disposed of nuclear material with little apparent concern that it was operating in the middle of a major metropolitan area. Among other things, historical documents show, scientists at the NRDL:
– Oversaw the dumping of huge amounts of contaminated sand and acid into San Francisco Bay after they were used in attempts to clean irradiated ships.
– Spread radioactive material on- and off-base, as if it were fertilizer, to practice decontamination.
– Burned radioactive fuel oil in a boiler, discharging the smoke into the atmosphere.
– Sold radioactive ships as scrap metal to a private company in Alameda.
– Hung a source of cobalt-60, a nuclear isotope that emits high-energy electromagnetic radiation similar to X-rays, in San Francisco Bay for two weeks, apparently just to see what would happen.
– Conducted human experiments that included requiring people to drink radioactive elements.
– Experimented with significant amounts of a wide variety of long-lived radiological poisons, including plutonium, cesium, uranium, thorium and radium.
– Studied and disposed of thousands of irradiated mice, rats, dogs, goats, mules, and pigs, among other animals. At one point, the lab owned a ranch in Contra Costa County used specifically to raise animals for radiation testing.
– Sought permission to dump 1,000 gallons of liquid waste containing "small amounts of fission products" into San Francisco Bay, as an experiment to study how tidal action would dilute the radioactivity. The experiment was meant as a precursor to the disposal of 1,000 gallons of liquid radioactive waste in the bay every day. (The documents do not say whether the experiment or the daily dumping occurred.)
— Davis, Lisa, Fallout, SF Weekly
Contamination
The first use of radioactive materials at NRDL predated the issuing of licenses by the Atomic Energy Commission, but the AEC later issued licenses for a broad spectrum of radioactive materials to be used in research at the NRDL. Radioactive materials specific to nuclear weapon testing were exempted from AEC licensing. For closure of the NRDL in 1969, the AEC issued licenses for decommissioning activities. AEC licenses for the shipyard and NRDL were terminated in the 1970s.
The NRDL testing and decontamination activities caused significant contamination of the shipyard site...
The US Navy completed a Historical Radiological Assessment of the Hunter's Point Shipyard in 2004, including the known NRDL facilities on the property, years after the SF Weekly article cited declassified documents showing that many sites and buildings used by NRDL were not included in the Navy's list of sites with potential for radiological contamination. Many of the buildings formerly used by NRDL had been razed by that point.
The former shipyard site is still being decontaminated...

https://en.wikipedia.org/wiki/Boiler_(power_generation)
Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/
A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
A boiler or steam generator is used wherever a source of steam is required. The form and size depends on the application: mobile steam engines such as steam locomotives, portable engines and steam-powered road vehicles typically use a smaller boiler that forms an integral part of the vehicle; stationary steam engines, industrial installations and power stations will usually have a larger separate steam generating facility connected to the point-of-use by piping. A notable exception is the steam-powered fireless locomotive, where separately-generated steam is transferred to a receiver (tank) on the locomotive...

https://en.wikipedia.org/wiki/Water-tube_boiler
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam.
High Pressure Water Tube Boiler:
The heated water then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam will reenter the furnace through a superheater to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore used to drive turbines, since water droplets can severely damage turbine blades.
Cool water at the bottom of the steam drum returns to the feedwater drum via large-bore 'downcomer tubes', where it pre-heats the feedwater supply. (In large utility boilers, the feedwater is supplied to the steam drum and the downcomers supply water to the bottom of the waterwalls). To increase economy of the boiler, exhaust gases are also used to pre-heat the air blown into the furnace and warm the feedwater supply. Such watertube boilers in thermal power stations are also called steam generating units.
The older fire-tube boiler design, in which the water surrounds the heat source and gases from combustion pass through tubes within the water space, is a much weaker structure and is rarely used for pressures above 2.4 MPa (350 psi). A significant advantage of the watertube boiler is that there is less chance of a catastrophic failure: there is not a large volume of water in the boiler nor are there large mechanical elements subject to failure.
A water tube boiler was patented by Blakey of England in 1766 and was made by Dallery of France in 1780...
Their ability to work at higher pressures has led to marine boilers being almost entirely water-tube. This change began around 1900, and traced the adoption of turbines for propulsion rather than reciprocating (i.e. piston) engines – although watertube boilers were also used with reciprocating engines...

The United States federal civil service is the civilian workforce (i.e., non-elected and non-military public sector employees) of the United States federal government's departments and agencies. The federal civil service was established in 1871 (5 U.S.C. § 2101). U.S. state and local government entities often have comparable civil service systems that are modeled on the national system, in varying degrees.
The U.S. civil service is managed by the Office of Personnel Management, which as of December 2011 reported approximately 2.79 million civil servants employed by the federal government, including employees in the departments and agencies run by any of the three branches of government (the executive branch, legislative branch, and judicial branch), including over 600,000 employees in the U.S. Postal Service...
In the early 19th century, positions in the federal government were held at the pleasure of the president—a person could be fired at any time. The spoils system meant that jobs were used to support the American political parties, though this was gradually changed by the Pendleton Civil Service Reform Act of 1883 and subsequent laws. By 1909, almost two-thirds of the U.S. federal workforce was appointed based on merit, that is, qualifications measured by tests. Certain senior civil service positions, including some heads of diplomatic missions and executive agencies, are filled by political appointees. Under the Hatch Act of 1939, civil servants are not allowed to engage in political activities while performing their duties. In some cases, an outgoing administration will give its political appointees positions with civil service protection in order to prevent them from being fired by the new administration; this is called "burrowing" in civil service jargon.
U.S. Civil Service Commission
Public support in the United States for civil service reform strengthened following the assassination of President James Garfield. The United States Civil Service Commission was created by the Pendleton Civil Service Reform Act, which was passed into law on January 16, 1883. The commission was created to administer the civil service of the United States federal government. The law required federal government employees to be selected through competitive exams and basis of merit; it also prevented elected officials and political appointees from firing civil servants, removing civil servants from the influences of political patronage and partisan behavior. However, the law did not apply to state and municipal governments.
Effective January 1, 1978, the commission was renamed the Office of Personnel Management under the provisions of Reorganization Plan No. 2 of 1978 (43 F.R. 36037, 92 Stat. 3783) and the Civil Service Reform Act of 1978.
The United States Civil service exams have since been abolished for many positions, since statistics show that they do not accurately allow hiring of minorities according to the affirmative action guidelines...

Driving is the controlled operation and movement of a motor vehicle, including cars, motorcycles, trucks, and buses. Permission to drive on public highways is granted based on a set of conditions being met and drivers are required to follow the established road and traffic laws in the location they are driving...
Driving in traffic is more than just knowing how to operate the mechanisms which control the vehicle; it requires knowing how to apply the rules of the road (which ensures safe and efficient sharing with other users). An effective driver also has an intuitive understanding of the basics of vehicle handling and can drive responsibly.
Although direct operation of a bicycle and a mounted animal are commonly referred to as riding, such operators are legally considered drivers and are required to obey the rules of the road. Driving over a long distance is referred to as a road trip.
In some countries, a basic both practical and theoretical knowledge of the rules of the road is assessed with a driving test(s) and those who pass are issued with a driving license...
A driver must have physical skills to be able to control direction, acceleration, and deceleration. For motor vehicles, the detailed tasks include:
Proper hand placement and seating position
Starting the vehicle's engine with the starting system
Setting the transmission to the correct gear
Depressing the pedals with one's feet to accelerate, slow and stop the vehicle and
If the vehicle is equipped with a manual transmission, to modulate the clutch
Steering the vehicle's direction with the steering wheel
Applying brake pressure to slow or stop the vehicle
Operating other important ancillary devices such as the indicators, headlights, parking brake and windshield wipers
Speed and Skid control
Mental skill
Avoiding or successfully handling an emergency driving situation can involve the following skills:
Observing the environment for road signs, driving conditions, and hazards
Awareness of surroundings, especially in heavy and city traffic
Making good and quick decisions based on factors such as road and traffic conditions
Evasive maneuvering
Understanding vehicle dynamics
Left- and right-hand traffic...

https://en.wikipedia.org/wiki/LGM-118_Peacekeeper
Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/
The LGM-118 Peacekeeper, also known as the MX missile (for Missile-eXperimental), was a land-based ICBM deployed by the United States starting in 1986. The Peacekeeper was a MIRV missile that could carry up to 10 re-entry vehicles, each armed with a 300-kiloton W87 warhead in a Mk.21 reentry vehicle (RV). A total of 50 missiles were deployed starting in 1986, after a long and contentious development program that traced its roots into the 1960s.
MX was designed to allow the US to ride out a sneak attack by the Soviet ICBM fleet and then launch a counterattack. In order for the counterattack to be effective, MX had to have three qualities: the ability to be rapidly re-targeted, so that it would attack only those Soviet missiles known to be in their silos; enough accuracy to allow a small warhead to kill an enemy silo, so that more warheads could be packed on a single MX missile; and a basing system that meant enough of the missiles would survive an attack that the counterattack would be effective. Among these three, the basing issue remained an unsolved problem and the subject of much criticism during the MX's development.
After considerable debate, President Ronald Reagan announced that the newly named Peacekeeper would be put into service in existing LGM-30 Minuteman silos, a temporary solution until a final basing solution was decided. During the same period, the United States and the Soviet Union were involved in negotiations on the START II treaty, under which ICBMs were allowed to carry only a single warhead each. Because the Minuteman could carry a single warhead for far less money the United States agreed to remove the Peacekeeper from their nuclear force in this treaty. Although START II was not ratified by the United States, the missiles were removed, with the last one going out of service on 19 September 2005. Their advanced W87 warheads were moved to Minuteman III.
The private launch firm Orbital Sciences Corporation has developed the Minotaur IV, a four-stage civilian expendable launch system using old Peacekeeper components...
The Air Force had depended on engineering support from TRW during the early days of the development of their ICBM force. In 1960 a number of TRW and other engineers involved in the ICBM program formed The Aerospace Corporation, initially working on the Mercury spacecraft, X-20 Dynasoar and various ICBM projects. In 1964, the Air Force contracted them to consider a wide variety of survivable ICBM solutions, under the name "Golden Arrow".
The project considered road, rail, submarine and air-launched weapons...
In 1976, Congress refused to fund MX using a silo-based system on grounds of vulnerability, and the project was halted. Several new proposals were made for alternate basing arrangements, including mobile basing in railway cars that would be sent out into the nation's rail network during times of heightened threat levels, and more complex systems of deeply buried silos under mesas that would include systems to quickly dig themselves out after an attack.
Eventually, the program was reinstated in 1979 by President Carter, who authorized deployment of 200 missiles throughout eastern Nevada and western Utah. The deployment would occur in a system of multiple protective shelters linked by underground or aboveground roads, the so-called "Racetrack" proposal...
Reagan canceled the new shelter system in 1981, calling it "a Rube Goldberg scheme". He proposed deploying an initial force of missiles in the approximately 60 existing Titan II silos, removing those now outdated missiles from service. The silos would be modified for much greater strength, and a number of Minuteman III silos similarly adapted over time to bring the force to a total of 100 missiles...

Civil Aerospace Medical Institute (CAMI) is the medical certification, education, research, and occupational medicine wing of the Office of Aerospace Medicine (AAM) under the auspices of the Federal Aviation Administration Office of Aviation Safety. The Institute's primary goal is to enhance aviation safety...
America's first successful flight was in 1903, but amazingly, five years would pass before the first fatal aviation accident. Since then, safety has been an important concern. In 1926, the Civil Aeronautics Act marshaled the talents of the medical profession to certify that all aviators are physically fit to fly. In August 1958, the Federal Aviation Act, which created an independent federal agency, was passed. As part of the organizational changes that followed the FAA Act of 1958, an Office of the Civil Air Surgeon was established. On 31 October 1959 plans were announced to create the Civil Aeromedical Research Institute (CARI) which was established in 1961. A new CARI building was opened at the Aeronautical Center in Oklahoma City.
In 1965 the Institute's organizational scope and structure were enlarged and CARI was renamed the Civil Aeromedical Institute (CAMI). The organizational changes designated all research laboratories as an aeromedical research branch along with aeromedical certification, aeromedical education, and a medical clinic branch. The Institute's people— scientists, engineers, physicians, medical specialists, educators, pilots, technicians, communicators, and others — all merged as a team. In 2001, CAMI was expanded to incorporate commercial space transportation, and its name was changed to the Civil Aerospace Medical Institute.
The principal concern at CAMI is the human element in flight—pilots, passengers, air traffic controllers, and the entire human support system that embraces civil aviation. Researchers study the factors that influence human performance in the aerospace environment, find ways to understand them, and communicate that understanding to the aviation community.
Over 280 scientists, physicians, educators, pilots, technicians, and administrative personnel work at CAMI, which is located at the Mike Monroney Aeronautical Center (MMAC) in Oklahoma City, Oklahoma, at the corner of Southwest 66th Street and MacArthur Boulevard. On static display in front of the CAMI building is a Lear Fan, one of only three ever produced...

The Waldorf Astoria New York is a luxury hotel in Midtown Manhattan in New York City. The structure, at 301 Park Avenue between 49th and 50th streets, is a 47-story 625 ft (191 m) Art Deco landmark designed by architects Schultze and Weaver, which was completed in 1931. The building was the world's tallest hotel from 1931 until 1963, when it was surpassed by Moscow's Hotel Ukraina by 23 feet (7.0 m). An icon of glamour and luxury, the current Waldorf Astoria is one of the world's most prestigious and best-known hotels. Waldorf Astoria Hotels & Resorts is a division of Hilton Hotels, and a portfolio of high-end properties around the world now operate under the name, including in New York City. Both the exterior and the interior of the Waldorf Astoria are designated by the New York City Landmarks Preservation Commission as official landmarks.
The original Waldorf–Astoria was built in two stages, as the Waldorf Hotel and the Astoria Hotel, which accounts for its dual name. That original site was situated on Astor family properties along Fifth Avenue, opened in 1893, and designed by Henry J. Hardenbergh. It was demolished in 1929 to make way for the construction of the Empire State Building.
Particularly after its relocation, the Waldorf Astoria gained international renown for its lavish dinner parties and galas, often at the center of political and business conferences and fundraising schemes involving the rich and famous. Particularly after World War II it played a significant role in world politics and the Cold War, culminating in the controversial World Peace Conference of March 1949 at the hotel, in which Stalinism was widely denounced. Conrad Hilton acquired management rights to the hotel on October 12, 1949, and the Hilton Hotels Corporation finally bought the hotel outright in 1972. It underwent a $150 million renovation by Lee Jablin in the 1980s and early 1990s, and in October 2014 it was announced that the Anbang Insurance Group of China had purchased the Waldorf Astoria New York for US$1.95 billion, making it the most expensive hotel ever sold. On July 1, 2016, Anbang announced that it would convert some of the Waldorf's hotel rooms into condominiums, closing the hotel for a three-year renovation on March 1, 2017. The renovated structure will house 375 hotel rooms and 375 brand-new residential condos.
The Waldorf Astoria and Towers has a total of 1,413 hotel rooms as of 2014. In 2009, when it had 1,416 rooms, the main hotel had 1,235 single and double rooms and 208 mini suites, while the Waldorf Towers, from the 28th floor up to the 42nd, had 181 rooms, of which 115 were suites, with one to four bedrooms. Several of the luxury suites are named after celebrities who lived or stayed in them such as the Cole Porter Suite, the Royal Suite, named after the Duke and Duchess of Windsor, the MacArthur Suite and the Churchill Suite. The most expensive room, the Presidential Suite, is designed with Georgian-style furniture to emulate that of the White House. It was the residence of Herbert Hoover from his retirement for over 30 years, and Frank Sinatra kept a suite at the Waldorf from 1979 until 1988. The hotel has three main restaurants: Peacock Alley, The Bull and Bear Steak House, and La Chine—a new Chinese restaurant that replaced Oscar's Brasserie in late 2015. Sir Harry's Bar, also located in the hotel, is named after British explorer Sir Harry Johnston...

https://en.wikipedia.org/wiki/Amphibious_warfare
Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/
Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign specialised watercraft were increasingly designed for landing troops, materiel and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs (rigid inflatable boats) and from mini-submersibles.
The term amphibious first emerged in the USA during the 1930s after design of the Landing Vehicle Tracked where the first prototypes were named Alligator and Crocodile, though neither species is amphibian. Amphibious warfare includes operations defined by their type, purpose, scale and means of execution. In the British Empire at the time these were called combined operations which were defined as "...operations where naval, military or air forces in any combination are co-operating with each other, working independently under their respective commanders, but with a common strategic object." All armed forces that employ troops with special training and equipment for conducting landings from naval vessels to shore agree to this definition.
Since the 20th century an amphibious landing of troops on a beachhead is acknowledged as the most complex of all military maneuvers. The undertaking requires an intricate coordination of numerous military specialties, including air power, naval gunfire, naval transport, logistical planning, specialized equipment, land warfare, tactics, and extensive training in the nuances of this maneuver for all personnel involved...
https://en.wikipedia.org/wiki/Amphibious_assault_ship
An amphibious assault ship (also referred to as a commando carrier or an amphibious assault carrier) is a type of amphibious warfare ship employed to land and support ground forces on enemy territory by an amphibious assault. The design evolved from aircraft carriers converted for use as helicopter carriers (and as a result, are often mistaken for aircraft carriers), but includes support for amphibious landing craft, with most designs including a well deck. Coming full circle, some amphibious assault ships now have a secondary role as aircraft carriers, supporting V/STOL fixed-wing aircraft.
The role of the amphibious assault ship is fundamentally different from a standard aircraft carrier: its aviation facilities have the primary role of hosting helicopters to support forces ashore rather than to support strike aircraft. However, some are capable of serving in the sea-control role, embarking aircraft like Harrier fighters for CAP and anti-submarine warfare helicopters or operating as a safe base for large numbers of STOVL fighters conducting air support for the Marine expeditionary unit once it has gone ashore. Most of these ships can also carry or support landing craft, such as air-cushioned landing craft (hovercraft) or LCUs.
The largest fleet of these types is operated by the United States Navy, including the Tarawa class dating back to the 1970s and the larger Wasp-class ships that debuted in 1989. Amphibious assault ships are also operated by the French Navy, the Italian Navy, the Republic of Korea Navy, the Royal Australian Navy, the Royal Navy of the United Kingdom, the Spanish Navy and Armada de Chile.
Although the term amphibious assault ship is often used interchangeably with the more-general term amphibious warfare ship, it specifically applies only to large-deck amphibious ships such as the Landing Platform Helicopter (LPH), Landing Helicopter Assault (LHA), and Landing Helicopter Dock (LHD) types. This does not include the amphibious transport dock (LPD), and dock landing ship (LSD)...

'"THE BIG PICTURE" covers atomic missile command -- THE BIG PICTURE can take credit for doing another masterful job in coverage of the United States Army's only operative missile command in Europe. Stationed in Verona, Italy, is one of NATO's unique military units. Famous for its historical landmarks, architecture, and art, Verona is home base for the Southern European Task Force--SETAF. This newest offering follows the familiar pattern of previous episodes except that the story is new and is told for the first time on television. The story as told on film is particularly dramatic and forceful as it covers in detail the Army's newest mobile striking force with nuclear weapons capability. Seen are Italian and American troops training together on small arms ranges, helicopters flying high into the Alps on supply and survival missions, and Italian troops fighting a delaying action against an invader from the Northeast. Into the rugged foothills of the Alps, camera teams follow paratroopers who are dropped to reinforce the front line infantrymen.'

United States Army Africa (USARAF), also known as the Southern European Task Force (SETAF), is the United States Army service component command of United States Africa Command (USAFRICOM or AFRICOM).
USARAF's headquarters are located on Caserma Ederle and Caserma Del Din, Vicenza, Italy.
SETAF, now known as USARAF/SETAF has been stationed in Italy since 1955 and has a long history of operating on the African continent and partnering with African nations. During the past 15 years, SETAF has provided crisis response, disaster relief and humanitarian assistance on the continent.
On 3 December 2008 in Rome, Italy, an official announcement by the U.S. and Italian governments stated that SETAF would become USARAF, and one week later on 9 December 2008 USARAF was established as the Army Service Component Command of AFRICOM. According to the Army Times, this marked the end of the airborne chapter of the unit's history and the beginning of its new role as the Army component of AFRICOM...
In 2020, the Army announced that USARAF will merge with U.S. Army Europe to form a new command, U.S. Army Europe and Africa (USAREUR-AF). The two commands were consolidated on November 20, 2020...
SETAF was formally activated during a ceremony on 25 October 1955.
The headquarters, commanded by Maj. Gen. John H. Michaelis, was temporarily established at Camp Darby, near Livorno, Italy with units additionally stationed in Vicenza and Verona. Shortly after activation, SETAF moved the headquarters to Caserma Passalacqua in Verona, Italy. The troop strength reached 10,000 and SETAF was formally established with a U.S./Italian agreement.
In 1959, a third agreement brought significant changes to SETAF, to include assigning Italian Army personnel to the SETAF general staff to assist with unique bi-national responsibilities. In 1963, SETAF lent a helping hand to its Italian neighbors when a huge landslide forced a deluge of water over the Vajont Dam in the Piave Valley killing more than 2,000 people. SETAF helicopters were the first on the scene to provide assistance.
The headquarters moved again in 1965 to Caserma Carlo Ederle in Vicenza.
SETAF's mission and geographical area of responsibility increased in 1972 when the command enlarged its signal support unit and began controlling two Army artillery groups in Greece and Turkey.
With the assignment of the 1st Battalion, 509th Infantry (Airborne Battalion Combat Team) in 1973,l Which was later reflagged in 1983 as 4/325 ABCT Then in 1987, the battalion rotated assignments with 3/325 based in Fort Bragg, North Carolina. The battalion was again reflagged as 1/508 ABCT in 1996 as the 3/325 rejoined the 325th Infantry Regiment at Fort Bragg. SETAF accepted the missions of maintaining and deploying the battalion on its own or as part of the Allied Command Europe Mobile Force (Land). Throughout the 1970s and 80s, SETAF continued its tradition of helping their Italian neighbors whenever disaster struck.
Until 1992, SETAF was considered to be a logistical command, but changes in Europe resulting from the end of the Cold War also resulted in new missions for the unit. SETAF shifted focus to regional tactical operations as command and control headquarters for Army and joint units...

Mexico City (Spanish: Ciudad de México) is the capital and largest city of Mexico and the most-populous city in North America. Mexico City is one of the most important cultural and financial centres in the world. It is located in the Valley of Mexico (Valle de México), a large valley in the high plateaus in the center of Mexico, at an altitude of 2,240 meters (7,350 ft). The city has 16 subdivisions, formerly known as boroughs.
The 2009 population for the city proper was approximately 8.84 million people, with a land area of 1,485 square kilometers (573 sq mi). According to the most recent definition agreed upon by the federal and state governments, the population of Greater Mexico City is 21.3 million, which makes it the second largest metropolitan area of the Western Hemisphere (behind São Paulo, Brazil), the eleventh-largest agglomeration (2017), and the largest Spanish-speaking city in the world.
Greater Mexico City has a GDP of $411 billion in 2011, making Greater Mexico City one of the most productive urban areas in the world. The city was responsible for generating 15.8% of Mexico's GDP, and the metropolitan area accounted for about 22% of total national GDP. If it were an independent country, in 2013, Mexico City would be the fifth-largest economy in Latin America, five times as large as Costa Rica and about the same size as Peru.
Mexico's capital is both the oldest capital city in the Americas and one of two founded by indigenous people, the other being Quito, Ecuador. The city was originally built on an island of Lake Texcoco by the Aztecs in 1325 as Tenochtitlan, which was almost completely destroyed in the 1521 siege of Tenochtitlan and subsequently redesigned and rebuilt in accordance with the Spanish urban standards. In 1524, the municipality of Mexico City was established, known as México Tenochtitlán, and as of 1585, it was officially known as Ciudad de México (Mexico City). Mexico City was the political, administrative, and financial center of a major part of the Spanish colonial empire. After independence from Spain was achieved, the federal district was created in 1824.
After years of demanding greater political autonomy, residents were finally given the right to elect both a head of government and the representatives of the unicameral Legislative Assembly by election in 1997. Ever since, left-wing parties (first the Party of the Democratic Revolution and later the National Regeneration Movement) have controlled both of them. The city has several progressive policies, such as abortion on demand, a limited form of euthanasia, no-fault divorce, and same-sex marriage.
On 29 January 2016, it ceased to be the Federal District (Spanish: Distrito Federal or D.F.) and is now officially known as Ciudad de México (or CDMX), with a greater degree of autonomy. A clause in the Constitution of Mexico, however, prevents it from becoming a state within the Mexican federation, as it is the seat of power in the country, unless the capital of the country were to be relocated elsewhere...

https://en.wikipedia.org/wiki/Gemini_10
Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/
Gemini 10 (officially Gemini X) was a 1966 crewed spaceflight in NASA's Gemini program. It was the 8th crewed Gemini flight, the 16th crewed American flight, and the 24th [human] spaceflight of all time (includes X-15 flights over 100 kilometers (54 nautical miles))...
Gemini 10 was designed to achieve rendezvous and docking with an Agena Target Vehicle (ATV), and EVA. It was also planned to dock with the ATV from the Gemini 8 mission. This Agena's battery power had failed months earlier, and an approach and docking would demonstrate the ability to rendezvous with a passive object. It would be also the first mission to fire the Agena's own rocket, allowing them to reach higher orbits.
Gemini 10 established that radiation at high altitude was not a problem. After docking with their Agena booster in low orbit, Young and Collins used it to climb temporarily to 412.4 nautical miles (763.8 km). After leaving the first Agena, they then rendezvoused with the derelict Agena left over from the aborted Gemini 8 flight—thus executing the program's first double rendezvous. With no electricity on board the second Agena, the rendezvous was accomplished with eyes only—no radar.
After the rendezvous, Collins spacewalked over to the dormant Agena at the end of a 50-foot (15 m) tether, making him the first person to meet another spacecraft in orbit. Collins then retrieved a cosmic dust-collecting panel from the side of the Agena. As he was concentrating on keeping his tether clear of the Gemini and Agena, Collins' Hasselblad camera worked itself free and drifted away, so he was unable to take photographs during the spacewalk.
Flight
The Agena launched perfectly for the second time, after problems had occurred with the targets for Gemini 6 and 9. Gemini 10 followed 100 minutes later and entered a 86.3-by-145.2-nautical-mile (159.9 by 268.9 km) orbit. They were 970 nautical miles (1,800 km) behind the Agena. Two anomalous events occurred during the launch. At liftoff, a propellant fill umbilical became snared with its release lanyard. It ripped out of the LC-19 service tower and remained attached to the second stage during ascent. Tracking camera footage also showed that the first stage oxidizer tank dome ruptured after staging and released a cloud of nitrogen tetroxide. The telemetry package on the first stage had been disabled at staging, so visual evidence was the only data available. Film review of the Titan II ICBM launches found at least seven other instances of post-staging tank ruptures, most likely caused by flying debris, second stage engine exhaust, or structural bending. NASA finally decided that this phenomenon did not pose any safety risk to the astronauts and took no corrective action...
The last day of the mission was short and retrofire came at 70 hours and 10 minutes into the mission. They landed only 3.0 nautical miles (5.6 km) away from the intended landing site and were recovered by USS Guadalcanal.
The Gemini 10 mission was supported by the following U.S. Department of Defense resources: 9,067 personnel, 78 aircraft and 13 ships...

The Republic of Vietnam Navy (RVNN; Vietnamese: Hải quân Việt Nam Cộng hòa; HQVNCH) was the naval branch of the South Vietnamese military, the official armed forces of the former Republic of Vietnam (or South Vietnam) from 1955 to 1975. The early fleet consisted of boats from France. After 1955 and the transfer of the armed forces to Vietnamese control, the fleet was supplied from the United States. With assistance from the U.S., the VNN became the largest Southeast Asian navy, with 42,000 personnel, 672 amphibious ships and craft, 20 mine warfare vessels, 450 patrol craft, 56 service craft, and 242 junks...
The origins of the Viet Nam Navy (VNN) began in 1952 with the French Navy. In 1954, in accordance with the Elysée Accords, the French handed control of the armed forces to the Vietnamese, but at the request of the Vietnamese government, continued to be in charge of the Navy until 20 August 1955. By this time the Navy numbered about 2,000 personnel, with 22 vessels. The Vietnamese then received assistance in the development of the VNN from the United States Military Assistance Advisory Group...
In 1956, the North Vietnamese began infiltrating men and arms into the Republic of Vietnam's territory by sea. In response the VNN created the Coastal Junk Force (Vietnamese: Luc Luong Hai Thuyen) of junks manned by Regional Irregular Forces and local fishermen recruited for the occasion, to patrol the waters around the Demilitarized Zone. The force later came to be known as Coastal Groups (Vietnamese: Duyen doan), and patrolled the entire 1,200-mile (1,900 km) coastline. This force was under the control of the regional military zone commands rather than the Navy, and was not incorporated into the VNN until 1965, by which time it numbered over 100 vessels...
In the late 1950s the Vietnam Navy was being modernized and developed, receiving ships and training from the United States Navy. By 1961 the VNN had a force of 23 ships, the largest of which were LSMs, 197 boats, and 5,000 men. This was insufficient to counter the growing threat of enemy infiltration and the years 1962-1964 were marked by a rapid expansion; training facilities, repair bases, and support facilities were established; communications equipment and networks improved; and organization and administrative procedures strengthened. The number of ships increased to 44 and number of personnel to 8,100.
This process continued and by the end of 1967 the personnel strength of the VNN had increased to 16,300, with 65 ships, along with 232 vessels of the River Assault Group (RAG), 290 junks, and 52 miscellaneous craft. Throughout 1968 the VNN gave priority to the improvement and expansion of their training programs in anticipation of gaining increased responsibility in the war effort as well as additional assets from the US. By the end of 1968 plans for the turnover of the majority of the United States Navy assets in Vietnam had been formulated.
Vietnamization
In early 1969, President Richard M. Nixon formally adopted the policy of "Vietnamization". The naval part, called ACTOV ("Accelerated Turnover to the Vietnamese"), involved the phased transfer to Vietnam of the U.S. river and coastal fleet, as well as operational command over various operations. In mid-1969, the VNN took sole responsibility for river assault operations when the U.S. Mobile Riverine Force stood down and transferred 64 riverine assault craft to the VNN. On 10 October 1969 80 Patrol Boat, Rivers (PBR) were transferred to the VNN at the Saigon Naval Shipyard, the PBRs were divided into four River Patrol Groups (RPGs) as part of Task Force 212.
By the end of 1970, the U.S. Navy ceased all operations throughout South Vietnam, having transferred a total of 293 PBRs and 224 riverine assault craft to the VNN...

The United States Naval Academy (USNA, Annapolis, or simply Navy) is a federal service academy adjacent to Annapolis, Maryland. Established on 10 October 1845, under Secretary of the Navy George Bancroft, it is the second oldest of the five U.S. service academies, and educates officers for commissioning primarily into the United States Navy and United States Marine Corps. The 338-acre (137 ha) campus is located on the former grounds of Fort Severn at the confluence of the Severn River and Chesapeake Bay in Anne Arundel County, 33 miles (53 km) east of Washington, D.C. and 26 miles (42 km) southeast of Baltimore. The entire campus (known to insiders as "the Yard") is a National Historic Landmark and home to many historic sites, buildings, and monuments. It replaced Philadelphia Naval Asylum, in Philadelphia, that served as the first United States Naval Academy from 1838 to 1845 when the Naval Academy formed in Annapolis.
Candidates for admission generally must both apply directly to the academy and receive a nomination, usually from a member of congress. Students are officers-in-training with the rank of midshipman. Tuition for midshipmen is fully funded by the Navy in exchange for an active duty service obligation upon graduation. Approximately 1,200 "plebes" (an abbreviation of the Ancient Roman word plebeian) enter the Academy each summer for the rigorous Plebe Summer. About 1,000 midshipmen graduate. Graduates are usually commissioned as ensigns in the Navy or second lieutenants in the Marine Corps, but a small number can also be cross-commissioned as officers in other U.S. services, and the services of allied nations. The United States Naval Academy has some of the highest paid graduates in the country according to starting salary. The academic program grants a bachelor of science degree with a curriculum that grades midshipmen's performance upon a broad academic program, military leadership performance, and mandatory participation in competitive athletics. Midshipmen are required to adhere to the academy's Honor Concept...
The first nautical school for officers was conceived by Commodore Arthur Sinclair in 1819 while in command of the Norfolk Navy Yard. Due to his zeal and perseverance, the "Nautical School" was opened on board the frigate Guerriere on 3 Dec 1821 with between 40 and 50 midshipmen attached to the ship. The curriculum was diversified with Naval Tactics, Astronomy, Geography, French, History, English Grammar, and International Relations. The school operated until 1828, when Guerriere was ordered to duty in the Pacific. It was from that small start that the U.S. Naval Academy at Annapolis grew.
The history of the Academy can be divided into four eras: 1) use of original Fort Severn 1845–1861, 2) "Porter's Academy" 1865–1903, 3) "Flagg Academy" 1903–1941, 4) modern era 1941–present...
