Corrected entry: When Terry takes out the Navy Seal with a hammer, she throws it and it spins in the air, like a tomahawk. The tomahawk does this because it is carefully balanced, unlike a hammer, which has a heavy weight at one end (the head) the hammer would have flown straight.
Corrected entry: The military is content to acknowledge a missing B2 because a few people may notice one took off from a base and didn't come back (maybe it was transferred to a different base?). But after the detonation in the mine, they decide to cover it up as an earthquake. Seismologists all over the world can easily tell the difference between a nuclear detonation and an earthquake. In fact, some are dedicated to this task to monitor the Comprehensive Test Ban Treaty, so the whole world would know that the US violated the treaty and tried to claim it was an earthquake.
Corrected entry: When Slater and Travolta are flying the stealth bomber, the two nuclear weapons are shown in adjacent racks in the bomb bay. On the computer display in the cockpit, the weapons are shown with an empty rack in between them.
Corrected entry: In the scene when Travolta ejects from the Stealth, they are flying "at 400 feet and 800 miles an hour. At that speed without a helmet or face protection, Travolta's face would be mush.
Corrected entry: What the hell are uncoded circuit boards?
Corrected entry: When Hale and Terry first meet and they're wrestling over the gun, you can see the orange nubby that indicates it is not a real gun.
Corrected entry: After Hale arms the nuclear weapon (and only has thirty minutes to dispose of it), he and the park ranger decide to lower the weapons into the mine shaft (and potentially get trapped down there with them because bad guys are coming). Instead of using the elevator, why not just drop the bombs into the shaft? If the armed one doesn't explode, fine. If it does, big deal; it's at the bottom of a half-mile deep mine.
Corrected entry: Why on earth does Teri arrest Hale? In what reality is it illegal to parachute from a crashing aircraft into a National Park? Is the pilot supposed to wait until he has flown out of her jurisdiction before he ejects? She handcuffs him - a man who may be distressed or injured after ejecting from a crashing bomber! What planet is she on?
Corrected entry: Wilkins and the rest of the Air Force team running this exercise are supposedly at Whiteman Air Force Base, Missouri, as stated by Pritchett when he's talking about the reporters in lawn chairs. There is no way they would have felt the tremors from an underground explosion in Utah.
Corrected entry: When the bomber is shown being towed out of the hangar it is being directed by a ground crewman with glow-sticks. While under tow the pilot has no control over the steering of the aircraft and the tractor driver can, presumably, see exactly where he is going and needs no guidance. The ground crewman is not only completely superfluous, he's in the way.
Corrected entry: In the final fight scene in the train, Christian Slater knocks Travolta down and grabs the remote control. Travolta told him beforehand that he can press one button to detonate the bomb and the other button to disarm. You can hear Slater pressing a button two or three times and nothing happens. But when he gets the remote again in the end, he presses it once and it disarms the bomb.
Corrected entry: Heroes enter underground river which carries them to safety, 2000ft up hill.
Corrected entry: Kelly (Howie Long) was supposed to die early on in the film, but Woo rewrote it so he was in it till the end.
Corrected entry: In the opening boxing scene between Hale and Deakins, they would be wearing mouthguards and helmets.
Corrected entry: The EMP that brings down the chopper for some reason has no effect on the circuits of the remaining nuke, nor or Deakins' watch which he continues to use afterwards. It would fry them irrespective of if they were turned off or not; similarly the same effect would prevent their jeep from working afterwards.
Corrected entry: When they use the helicopter to "give those guys a hair cut" towards the end of the film the rotor blades do some serious damage to one of the guys. However, in reality this would cause serious damage to the blades themselves and would most likely cause them to stall as there would be a sudden force put upon them.
Corrected entry: Moments before Travolta attempts to shoot Slater in the B-2 cockpit, Slater says something along the lines of how he enjoys flying a 2 billion dollar plane 800 miles per hour 100 feet off the ground. The problem with this is, that the aircraft would be traveling faster than the speed of sound at 800mph. We know that objects traveling faster than the speed of sound will create a sonic boom. Stealthy aircraft such as the B-2, travel at high subsonic speeds, so as not to create a sonic boom, which would alert enemy forces on the ground to the presence of an aircraft in the vicinity.
