Continuity mistake: When Christian Slater and the ranger are radioing for help in the ranger's truck, the enemy helicopter comes from behind a ridge and shoots at them. They get out of the way, and the bullet fire continues and hits the truck on the driver side door, the roof above, and then the ground after that. In the next scene, you can clearly see bullet holes on the hood, going from front to back, but the fire was from right to left.
New this month Continuity mistake: During the fight between John Travolta and Christian Slater in the train car towards the end of the film, the amount of blood around John Travolta's mouth changes between shots.
New this month Plot hole: There is no logical reason as to why two pilots on a training exercise would be given classified info such as the access codes for the nukes. Also it makes no sense as to why they would be carrying two LIVE nuclear warheads with them in the first place if the whole exercise was to test the bomber's stealth capability against the radar from the base.
Other mistake: When Christian Slater shoots 9 or 10 shots out of a 6-shooter, there is no possible way that he could have had time to reload in the time allotted.
Continuity mistake: In the gun fight in the mine shaft, Christian Slater pulls the hammer down on his pistol, then seconds later it's back up.
Factual error: The United States Air Force does NOT, ever, allow its pilots to box competitively! Ground staff, yes; pilots, no, never. A pilot can be suspended from flying if he/she receives a blow to the head in day-to-day life; boxing is right out. Almost all air forces (the RAF included) impose this rule.
Continuity mistake: In the scene in the copper mine, Christian Slater accidentally arms the bomb. As it counts down it is at 26 minutes. Later it counts down to 22 minutes. When John Travolta finds the bomb and begins stroking it the timer is back to 26 minutes.
Continuity mistake: When Christian Slater and the ranger are getting into the boat, there is a mysterious pair of binoculars that keeps appearing and disappearing.
Other mistake: When Terry stands in the valley and the stealth passes above her, you can clearly see that a part of the B2 disappears behind a mountain that is several kilometers away before it has flown just a hundred metres away from Terry.
Continuity mistake: In the big fight scene in the end John Travolta gets hit in the face and has blood all over his face and the front of his shirt. This keeps disappearing.
Continuity mistake: When Slater has captured the Hummer, Travolta slams into Slater's car which wrecks the right front light. Seconds later when Travolta arrives at the mine the front light is in one piece.
Continuity mistake: Near the end of the movie, the underground nuclear bomb is detonated, creating shock waves and rippling in the ground beneath the Hummer getaway vehicle. The ripples are huge and come in waves, yet when the explosion subsides, and they drive away, the dirt road isn't rippled or disturbed at all.
Continuity mistake: After the nuclear bomb is detonated, the helicopter spins out of control and crashes in front of the Hummer. Moments later, a camera shot from behind the Hummer shows the road in front of it to be clear, and the Hummer drives away without the helicopter being anywhere in sight.
Continuity mistake: In the closing fight sequence between Slater and Travolta, Travolta takes out a $20 bill, folded, and sets it under the remote for the nuke. Later, when they show the remote again, the bill is shown unfolded, in fact it is flat. When Christian picks the scorched bill off of the plant it is still flat.
Continuity mistake: When Hale throws the gas bomb at Deakins' hummer, you notice that the damage to the right side of the front end from Kelly ramming the other hummer is magically gone.
Continuity mistake: When Kelly fires at the hummer, you see that he punctures the gas tank. On hummers, the gas tank is in the middle of the underside. What he shot was the floorboard.
Continuity mistake: When Hale shoots into the train from the helicopter, he wounds Deakins in the right arm, but later during the movie, the wound is nowhere to be seen. Especially during the fight scene at the end when Deakins takes off his jacket. There's no blood or wound anywhere on his right arm.
Continuity mistake: When Terry and Hale first meet, Terry says "You're under arrest until we can get this sorted out", and puts the handcuffs on his right wrist. When he kicks her off, the handcuffs are on his left wrist.
Continuity mistake: When we see Terry again after her escapee in the river with Hale, her hair and clothes are in perfect shape. Did she have a comb and hairspray on her?
Continuity mistake: Toward the end of the movie, after the nuke has been armed in the mine and both groups are driving Hummers, John Travolta switches off the engine and informs his passengers that when the nuke goes off, the electro-magnetic pulse (EMP) will disable any vehicle that is running. Little does John (and apparently the movie's director) know, but EMP will fry any and all electrical circuits, whether or not the vehicle is running.
