Corrected entry: Right before The Windsor flight crashes, the stewardess tells two passengers that they've made arrangements so they would make their next flight. Obviously this could only be done with communication with the ground. If they had sky phones the tower would have called them to warn what was happening.Michael Prete
Corrected entry: Bruce is sitting in what looks like a C-130 while terrorists throw grenades in it through the window. Never mind the grenades going off too late, because they wouldn't all have made it through the small window anyway. In fact some of those grenades would've bounced back killing the terrorists also, which would've made for a surprising end to this movie. (01:17:45)
Corrected entry: Since the terrorists have implausibly taken over all the radios at the airport, the good guys use the marker beacons to communicate with the airplanes. Even if they could be modified to talk rather than beep, marker beacons (outer, middle and inner) are on the approach path of a runway, and only transmit to an aircraft as it passes overhead. The signal is only picked up by an aircraft's marker beacon receiver, if so equipped. There is not enough time to get a message. Nor could a marker beacon be used to broadcast to a large number of airplanes. The outer marker is only 5 miles from the airport. At most, one airplane would be holding over the outer marker.

Corrected entry: Dick locks the door using the slide lock inside, so Holly couldn't have got in to electrocute him.
Corrected entry: Prior to the 747 take off, Major Grant is sucked by one of the engines and all we see is blood being spit from its exhaust. Turbofans are very sensitive and would collapse after sucking a heavy bird (like a vulture), but this one remains intact after sucking a 200 lb man. (01:47:40)
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. (00:45:45)smd9
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. (01:51:35)
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. (00:52:40)
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. (01:23:20)
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. (01:38:20)
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. (00:24:20)Tormoni
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
Factual error: In circling over Washington Dulles, a plane would fly over several airports that they could land at with perfect communication, including Richmond, Baltimore, Andrews AFB, etc. Also, there is no communication from the airport to the plane but the plane would be in range of no fewer than 15 transmitting stations that could have relayed messages.
