US Air Force Video News Release VNR-7
Originally a public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

The Autobahn (German plural Autobahnen) is the federal controlled-access highway system in Germany. The official German term is Bundesautobahn (plural Bundesautobahnen, abbreviated BAB), which translates as "federal motorway". The literal meaning of the word Bundesautobahn is "Federal Auto(mobile) Track".
German Autobahnen are widely known for having no federally mandated speed limit for some classes of vehicles. However, limits are posted (and enforced) in areas that are urbanised, substandard, accident-prone, or under construction. On speed-unrestricted stretches, an advisory speed limit (Richtgeschwindigkeit) of 130 kilometres per hour (81 mph) applies. While driving faster is not illegal as such in the absence of a speed limit, it can cause an increased liability in the case of a collision (which the mandatory auto insurance has to cover); courts have ruled that an "ideal driver" who is exempt from absolute liability for "inevitable" tort under the law would not exceed Richtgeschwindigkeit.
A 2017 report by the Federal Road Research Institute reported that in 2015 70.4% of the autobahn network had only the advisory speed limit, 6.2% had temporary speed limits due to weather or traffic conditions, and 23.4% had permanent speed limits. Measurements from the German State of Brandenburg in 2006 showed average speeds of 142 km/h (88 mph) on a 6-lane section of autobahn in free-flowing conditions...
Similar to high-speed motorways in other countries, autobahns have multiple lanes of traffic in each direction, separated by a central barrier with grade-separated junctions and access restricted to motor vehicles with a top speed greater than 60 km/h (37 mph). Nearly all exits are to the right; rare left-hand exits result from incomplete interchanges where the "straight-on" leads into the exit. The earliest motorways were flanked by shoulders about 60 centimetres (24 in) in width, constructed of varying materials; right-hand shoulders on many autobahns were later retrofitted to 120 centimetres (47 in) in width when it was realized cars needed the additional space to pull off the autobahn safely. In the postwar years, a thicker asphaltic concrete cross-section with full paved hard shoulders came into general use. The top design speed was approximately 160 km/h (99 mph) in flat country but lower design speeds were used in hilly or mountainous terrain. A flat-country autobahn that was constructed to meet standards during the Nazi period, could support the speed of up to 150 km/h (93 mph) on curves.
The current autobahn numbering system in use in Germany was introduced in 1974. All autobahns are named by using the capital letter A, which simply stands for "Autobahn" followed by a blank and a number (for example A 8). The main autobahns going all across Germany have a single digit number. Shorter autobahns that are of regional importance (e.g. connecting two major cities or regions within Germany) have a double digit number (e.g. A 24, connecting Berlin and Hamburg)...
Just days after the 1933 Nazi takeover, Adolf Hitler enthusiastically embraced an ambitious autobahn construction project, appointing Fritz Todt, the Inspector General of German Road Construction, to lead it. By 1936, 130,000 workers were directly employed in construction, as well as an additional 270,000 in the supply chain for construction equipment, steel,concrete, signage, maintenance equipment, etc. In rural areas, new camps to house the workers were built near construction sites. The job creation program aspect was not especially important because full employment was almost reached by 1936...
The autobahns formed the first limited-access, high-speed road network in the world, with the first section from Frankfurt am Main to Darmstadt opening in 1935...
