In the beginning of Wargames, they have a drill for a missile launch which includes opening the exterior doors required for 10 missiles.
Would people living in the local area have been able to hear this and understand what the noise was?
I’m guessing the missile bases were isolated but how much so?
Was there a large audible sound in the scene? I’ve seen the movie more than a few times as a kid but don’t recall loud mechanical sounds of the missile doors. If it was a drill, no doubt they would had routinely opened the doors on the regular in the past, and at the bare minimum, they should have done due maintenance to ensure silky smooth and squeek free opening of said doors.
