- Awesome Music: Gant is walking towards the hangar; the camera pans down and a Scare Chord plays as we get our first look at the MiG-31. It helps that the music was composed and conducted by Maurice Jarre, of Doctor Zhivago fame.
- Hilarious in Hindsight:
- Thomas Hill (General Brown) and Freddie Jones (Kenneth Aubrey) appear together in one briefing scene. Hill would go on to play Mr. Koreander in The Never Ending Story and it sequel The Next Chapter, with Jones replacing him for the third film Escape from Fantasia.
- The nose/cockpit section of the Firefox bears a striking resemblance to the F-117 Nighthawk, which entered service the same year this movie came out.
- The original novel describes the titular aircraft as being similar in appearance to the MiG-25, which the real MiG-31, introduced around the same time as the film's release, did indeed end up resembling.
YMMV / Firefox
