I was stationed at Castle AFB from 1956 to 1960 (93rd Field Maintenance Squadron) and watched the filming of the flight line segments. I even have some black & white pictures of Natalie with some of my squadron mates. The high point was the low altitude flyover of a flight of B-52s. The segment where the landing gear is jammed was done in our maintenance hanger with the bomber on jacks with wheel well doors open. An iris on the lighting gave the impression of the wheel well doors opening as the iris was opened. In the finished film it looked very realistic. My one complaint was the scene of a B-52 flying with it's gear down after being refueled by a KC-97, that just wasn't done.
