That reminds of a documentary i watched in my high school history class called "The Atomic Cafe"
It was about the nuclear bomb, and its history, but it was done entirely using stock footage from the era. It had old training videos that the military used to show soldiers about the bomb, and what they should do in an attack. It was very interesting, and fun to watch.
It can actually be found over on D, such search "The Atomic Cafe"
