Trivia: The film-makers only had three vintage US aircraft for the production, namely two F4F Wildcat fighters and a PBY Catalina search plane. All of the other aircraft that appear are from either wartime footage or from previous war movies.
Another "Recycled Footage Segment" via Tora! Tora! Tora!: When 3 Officers on Midway come out of their bunker and say that the runway is still operational, the footage of the B-17 with the landing gear problem mentioned elsewhere is blatantly used.
