What a cool idea! The B-17s look especially good. Very creative and well done.
Hey Nath - the overdone part all depends. First off a number of the planes were Pacific fighters - it would be hot and humid and that would go a long way to prematurely age the film. Also, wartime quality was generally less than your premium film/paper. I've seen gun camera shots that look pretty close to some of those.
Certainly there were higher quality pictures taken - the Wizard of Oz was 1939 wasn't it? - but a lot depended on storage environment.
