Factual error: During the part where they're in NORAD and watching all of the Soviet "nukes" hit various bases in the US, a base in northern Maine is listed as, "Loring AFB 43 Bomb Wing." This was a real air force base, but it was the 42nd Bomb Wing that flew B-52s out of Loring. The 43rd Bomb Wing did exist, too, but it was based at Andersen Air Force Base, Guam, in the North Pacific.
Continuity mistake: The tour group comes in and they trick the black lady into pressing the red "launch" button that displays the welcome on the screen. Just before she presses it she has a 35 mm camera hanging around her neck, but in the next shot of the group standing in front of the panel her camera is gone.corona
Other mistake: Where the army officer is pushing the buttons on the wall panel to launch the missiles, on the both occasions you see it, the panel buckles highlighting the flimsy set.
Continuity mistake: Towards the end when the NORAD door is closing, they keep showing it opened further from shot to shot in order to delay how quickly the door actually is closing vs. how slow it really would have had to move in order to allow David and Dr. Falken to actually have still made it in.jerimiah
Factual error: The beginning starts out with two Strategic Air Command officers in a Minuteman Intercontinental Ballistic Missile (ICBM) Launch Control Facility (LCF) going through the strict procedures for launch of an ICBM. The crypto messages are being received by the LCF, the launch officers pull the launch sequence and confirm the crypto launch command (encoded message) matches that which is contained in the launch sequence - all very secret, and all very realistic. However, the missile they show in the movie powering up for launch is a Titan ICBM, and how you launch a Titan from a Minuteman LCF is beyond me.
