Plot hole: In one shot before the almost-collision between the C-123 and the Cessna, you see both of the planes on/above a runway. In the next shot, just before the almost-collision, you see the C-123 from behind, with the Cessna in front of it, but this shot is not on that runway anymore, it looks like a taxiway, and there is some airport building in close proximity at the end of it. Nobody would intend to land there (this is before the evasive maneuvre of both). (01:06:05)
Continuity mistake: Colm's car gets hooked up to the plane and then, after crashing into the watchtower, falls to the ground. If you watch the shots of the car falling you can see John Cusack's arms go from folded to at his side multiple times. You never see him move them, they just appear to have changed positions. (01:28:35)
Plot hole: Removing the radar transponder from the C123 would not render it invisible to radar – it's a huge aircraft with a large radar signature. It would be easily tracked by airport radar, and anyone who wanted to know would know exactly where it was going. How to identify which radar track is theirs? Easy. It's the one without the transponder signal.
Continuity mistake: Coe releases Pinball's dead body from the forward landing gear bay and pushes it out of the aircraft. The landing gear then starts to retract. Cut to a wide shot of the aircraft with Pinball's body falling away, and the forward landing gear is retracted, and the landing bay doors fully closed. Cut to Poe in the landing gear bay, and the gear is still retracting, and the bay doors are wide open. (00:52:00)
Factual error: At the beginning of the movie, Nicholas Cage is supposed to be an Airborne Ranger. His uniform is correct for someone being in the 75th Ranger Regiment but his hair is entirely too long. Rangers are required to keep their hair EXTREMELY short. (00:01:25)
Factual error: In the movie the officers are seen wearing brown shirts and pants. Officers in the federal bureau of prisons do not wear brown, they wear white shirts and grey pants. (00:14:40)
Character mistake: When Cyrus and Johnny-23 are talking they both pronounce the Spanish version of Johnny-23's name as Juaniyo. That is not how Johnny is pronounced in Spanish. It is pronounced Juanito with a T. Normally I would have chalked it up as a language barrier but Danny Trejo is of Spanish ancestry. He should have known better. (00:20:41)
Factual error: When John Cusack is driving the old Corvette to Lerner Field he shifts the car. He is going way too fast to be shifting from second to third so apparently he is shifting from fourth to overdrive. The only problem is that five speed transmissions weren't available until much later. In fact, on these old transmissions, shifting up and to the right from fourth would put you in reverse. (01:00:50)
Continuity mistake: When the plane is crashing into the hotel, it crashes into a white corvette. Then it cuts to another scene, then it cuts to back outside, and you see the plane crash into the corvette again, from a different angle. Then it does the same thing 2 more times, until the plane is actually stopped. After it cuts to another scene outside, you see the same corvette, with only a flaming piece of metal on the hood, not completely shattered like it should be. (01:37:30)
Other mistake: After Pinball douses "Cochise" with flammable liquid, the match he throws extinguishes before it leaves his hand. (00:22:45)
Continuity mistake: When Cameron and Diamond Dog go into the belly to inspect what's wrong with the landing gear, Cameron flips a switch to turn on the lights on the floor of the belly. When he does this, you can see a lot of boxes between the landing gear and the ladder that him and Diamond Dog climbed down. But, as they head to the back to look at the landing gear, all the boxes are now gone.
Character mistake: When they decide to crash land the plane and touch down on the road the pilot either doesn't cut power to the engines or doesn't shut them off. Towards the end, it looks like the engine is still at full power.
Continuity mistake: In the extended edition, after Johnny attacks Guard Bishop and is stopped by Cameron, the cons run back to the plane to escape, and all of a sudden Johnny appears from nowhere with a gun and is shot, when he was just on the plane being beaten up by Cameron, and is then shown being put in chains by Cameron back on board the plane.
