This movie was designed to showcase the US Air Force's brand-new B-52 Stratofortress bomber, and as such the studio received complete cooperation from the Air Force.
This was apparently the first film in which the US Air Force's new B-52 Stratofortress bomber was featured. It appeared in a number of films afterward, notably Le téléphone rouge (1963), Dr. Folamour ou : comment j'ai appris à ne plus m'en faire et à aimer la bombe (1964), and L'aube de l'apocalypse (1990).
Chuck's family car is a 1941 Buick Special.
The TV set in the home of Chuck's private-sector buddy is a 1956 Zenith console, possibly a "Gotham." Another 1956 Zenith, a "Plaza" or a "Cloister," is mounted in the wall of a diner.
