@George,
I didn't explain quite right. Through the war, me a baby or toddler, my dad was head of photo for the USAAF, based in Dayton, but with some roaming all over the US at different bases. He had gotten work when young as an early film editor (in the late '20s, far as I know).
His life turned out to be complicated, but, in the case of Twelve O'Clock High, he was able to obtain real flight films via his then clearance or whatever, and edit for the movie.
I didn't mean that all the flight scenes in the movie had his touch, just the real film ones.
mmm, now I want to check out Twelve O again.
