My favorite would be the movie Strategic Air Command starring Jimmy Stewart.The movie was made during the 1950’s but it showed the establishment of SAC and the reasons it was developed.
The photography in Strategic Air Command was spectacular. Truly artistic in every sense. And John Wayne in “Island in the Sky”.
Those C-47 cargo planes were the other stars of the movie. The flights scenes were amazingly filmed too.
And a recent one “The Aviator”, about Howard Hughes, beautifully depicted some spectacular flying scenes of US history.
