Corrected entry: Just before McClane drops down from the vent to rescue the guy that's about to be killed from be the terrorist dressed as a painter, he fires 9 shots, and then he drops down and proceeds to shoot 14 more shots in the process of killing other terrorists, without reloading. His gun could not have held that many rounds.
Corrected entry: At the end of the film when John and Holly get driven away on the back of what resembles a golf cart, the long shot of them clearly shows two dummies that nearly fall off when the cart sets off.
Corrected entry: The terrorists some how raise the elevation of the airport in relation to the ILS (instrument landing system). This causes one of the jets to crash. The ILS glide slope is broadcast from a fixed antenna beside the runway, 1000 feet from the approach end. The glide slope is fixed at (usually) 3 degrees. Even if someone changed the slope (ie, degrees of slant), it would still terminate on the runway at the touchdown zone. Besides, the pilots have charts that give all pertinent information about the ILS and also have altimeters, radar altimeters, ground proximity warning systems (GPWS), and brains (duh). All of those systems listed are on board the aircraft, independent of the ground based systems. They would not have descended into the ground even if the terrorists had tampered with the ILS.
Corrected entry: Colonel Stewart and his men arrive at the airport in a helicopter. So, where do they get the Army truck they drive around in?
Corrected entry: At the end of the film when the planes begin landing there is no reason for the planes to deploy emergency chutes and send the passengers outside into the snow. All aircraft landed safely without incident. They were simply low on fuel. Planes only evacuate if there is impending danger to passengers by remaining on board.Andy in Wasaga
Corrected entry: When McClane's wife is thinking about using the phone to call, there is a shot of the phone. Behind the phone, you can see a circular staircase. The aircraft she is on, an L1011 TriStar, has only one passenger deck.
Corrected entry: Look at the people carefully when they run out of the airport. They don't seem to have any hurry or rush. You have to watch single people to see it.
Corrected entry: When John McClain sends Officer Powell the fax of the fingerprints, notice the direction he feeds the page into the fax. The middle two fingers' prints are the first two prints to go across the scanner, followed by the outer two fingers' prints. With a fax, the first thing scanned is the first thing printed.Therefore, when Powell received the fax, the middle two prints should be at the bottom of the page with the outer two prints higher up on the page. You can see when Powell removes the page out of the machine that this is not the case.
Corrected entry: The interior of the plane which is deliberately crashed by the terrorists is of a BAC 1/11. I do not know any airline in the world which would choose to send a BAC 1/11 over the Atlantic from Europe due to it only being able to carry a limited number of passengers and short range capabilities.Jordan Hare
Corrected entry: The last scene shows the bad guys in their plane ready to take off - driving down the runway. Then Bruce gets from the helicopter to the plane's wing, fights with each bad guy, falls off, and the plane begins to take off - again. At no time did the plane turn to circle to another runway. It seems this runway was about 2 to 3 times as long as it should have been.Jack's Revenge
Corrected entry: When McClain is arguing with Lorenzo in the police station, McClain shoots the gun at him with the blanks in it to make his point. Lorenzo walks over to the phone, picks it up, and says, "This is Chief Lorenzo." It has been established throughout the movie that Lorenzo holds the rank of Captain.
Corrected entry: It is not possible that a Heckler & Koch MP5 repeats with blank rounds as seen during the fight at the church. An automatic weapon, such as an MP5, repeats with gas pressure, which only is strong enough when a bullet is in the barrel.
Corrected entry: Early in the film, McClane describes Cochrane's pistol to Lorenzo as a "Glock 7" which is made in Germany. While the model could easily be made up for the movie (there's no real Glock 7, and even the mostly non-metal models are easily detected), Glocks are Austrian, not German.
