One of the principles I have when working on location is that I want the models to interact with the environment.
Now that can be a bit tricky on a 15m 50' wide runway that's flat as a pancake.
But since runways usually have (incredibly long) arrows painted on them, there are still options if you can create some echo shapes, and as you can see, that's what we did.
And I'll bet you just had an association with "playing airplane" from your childhood or kidt pretending to be airplanes.
But everything counts.
Everything that will make you look longer than 3 seconds at a picture is a win in my book.
