Many of the scenes in Midway were taken from the film Tora, Tora, Tora!
There was one scene were the japs are strafing Midway Atoll, and you could see volcanic mountains in the background!
I should say I very much like the 1976 Midway, I have the DVD, but it did have its flaws also.
A goodly amount of live footage during the attack on Midway was taken by John Ford, the famous movie director.
He was advised to get underground with the command staff,
but chose to get into a shack near the action and film it.
