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.
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.
Corrected entry: In the scene where McClain lights the trail of jet fuel, and the fire catches up with the wing of the airplane, for 11 seconds there are several shots of the wing explosion showing fire moving from the rear to the front, engulfing the bad guys. In the very next shot, there is a side view of an airplane exploding from the front to the rear.
Corrected entry: When the aircraft start landing at the end, they all come in one after another, and we see them all parked at the end of the runway, (we don't see any of them turn off the runway onto the taxiways). That would never happen with commercial passenger aircraft. What if one of them had skidded on the ice and slammed into the rest? One would not land until the runway ahead was clear.
Corrected entry: In the beginning when the terrorists enter the baggage area they go in, in civilian attire with nary a blink from anyone. 1st off, I don't care how lax security is, someone would have noticed. In fact, when McClane approaches the door, a ramp worker is right beside it. Was he asleep a minute ago? 2nd, they seemed to open the door with no problem but when Bruce Willis tries, the door is locked. 3rd, why is there not a soul in the baggage area beside 3 men shooting guns?
Corrected entry: When Willis is trapped in the plane by the terrorists he escapes by using the ejector seat - however the plane is a C-132 (at least the body of a C-123, with studio-designed wings) and these planes don't have ejector seats.
Corrected entry: At the start of the film when Bruce Willis is getting his car towed, he says says to the police officer 'Come on, cut me some slack, will you. Look, I used to be a cop in New York city. I only moved to LA because my wife took a job there. Come on, what do you say. Here we are, in Washington DC. The heart of democracy' it was meant to be Dallas International Airport in Texas?
Corrected entry: At the beginning of the fight scene on the 747 wing, the door swings opens as if on simple hinges like a screen door. Boeing uses plug doors, a design where the entire door has to move inwards several inches before moving outwards.
Corrected entry: Bruce Willis takes two torches out on the runway to try and save the plane that the terrorists are crashing on purpose. He is waving his arms back and forth in a fanning motion. When Dennis Franz and Fred Thompson see him from the tower, the orange lights that are supposed to be Willis are simply flashing on and off.
Corrected entry: A major plot element is that the terrorists have taken over the airport's radio system and that the hero's can't communicate with the planes overhead. The characters go to extraordinary (fatal) lengths to attempt to gain access to a radio that they can use to talk to the airplanes. The problem with this is that there are airplanes at airports. Every airplane has multiple radios that could communicate with other airplanes. All the vehicles that drive around the airport have radios. People carry handhelds. There are desktop units all over an airport.
Corrected entry: When the terrorists are about to take off, McClane, before falling off the wing, releases a fuel valve, yet Stuart does not notice. However, the General flying the plane does not notice either. Since the stream of fuel is considerably strong, wouldn't there be a warning indicator in the cockpit?
Corrected entry: Throughout the film the exceptionally poor visibility is repeatedly refered to. In the scene where McClane is trying to prevent the aircraft crashing by waving flaming torches in the air the Controller can recognise him from the Control Tower through a small set of binoculars despite the facts that 1) it is dark, 2) it is snowing, 3) they have only met once before and 4) McClane is wearing a borrowed Airport coat. Even from the end of the runway where McClane is standing at its closest point to the Tower this would be impossible.
Corrected entry: when John, the airport police captain and his brother are in the car about to go to the hanger the car pulls out and hits the cab there is an external shot of the crash you see that the wind screen shatters but when the camera goes to the bonnet the wind screen is still intact.
Corrected entry: Bruce calls his wife and finds out that she should be landing soon. We then see the journalist from the first film making a huge fuss about being moved from first class, where he has been sitting for the entire journey. He hadn't been in Holly's compartment before due to his reaction when he first sees her. Why did they only just move him when the plane was about to land? He was sitting in first class the whole journey with no problem. Surely ten more minutes wouldn't hurt?
Corrected entry: John Amos plays an Army Major, and says that he taught William Sadler's Colonel Stuart "everything he knows." Well, this doesn't make any sense, especially if they are both from Special Forces units. Unless Stuart went through SF selection late in his career, he would not be getting instructed by someone two grades below him.
Corrected entry: The noise of the big English aircraft exploding should be heard far from the point of its explosion. But why didn't the waiting passengers in the hall hear it and panic? If it was too far, how McClane can arrive to Esperanza's aeroplane so quickly?
Corrected entry: You cannot fire 'blanks' and 'live' ammunition from the same weapon without fitting a BFA (blank firing attachment). When a live round is fired, the bullet moving up the barrel seals the barrel. The exploding gas pushes in two directions. One - forcing the bullet out the end and two - pushing the working parts back. The working parts then move forward and pick up a new round. The BFA seals the top of the barrel, as a live round would do. If a live round is fired through a BFA you would be lucky not to blow the barrel.
Corrected entry: When Willis is in the pilot's seat of Esperanza's plane, he ejects when grenades are thrown in by the terrorists. First of all, those aircraft are sealed tight and have no canopy or hatches to blow off for an ejection. In that case, ejection seats would be useless. Also in that scene, multiple grenades are thrown in the cockpit, yet it takes 23 seconds before any of them blow. The type of grenades they were using, which were US issue, have a fuse no longer than 7-8 seconds upon release.
Corrected entry: The error most fatal to this silly plot is the notion that shutting down the airport's communications will mean that no one can contact inbound aircraft. All one would have to do is go to any plane on the ground or use a handheld radio set to the tower frequency to advise inbound traffic of the problem. During the infamous blackout of 1965 that affected the entire northeastern U.S. for several hours, over 200 commercial aircraft landed safely at JFK airport in New York, in the dark, with no ILS, no runway lights, and no radio communication except radios working on aircraft sitting on the ground.
Corrected entry: When the major is fighting John on the plane wing there is a white spiral in the middle of the engine, but when the Major falls into the engine there is no spiral.
Corrected entry: If the terrorists had sailed off in the 747 in the end, what then? They had no way of protecting themselves from fighter planes, which would certainly have been on their tails. So what could their next move have been?
Corrected entry: McClane's fireman's jacket gets progressively bloodier throughout the film, but around the time when he is fighting the terrorists on the plane's wing, it is miraculously clean again.
Corrected entry: When the plane explodes at the end of the film all the planes circling can now tell where the ground is and start landing. Why did they not do this earlier when the Windsor (British) plane crashed?
Corrected entry: Now, I've never been to IAD (Dulles) or LAX but I've been in several airports and have never, ever seen a control tower in such close proximity to the terminal area that one can take an elevator to, let alone be so unsecure that civilians and reporters and camera crews can go into unmolested.
Corrected entry: The plane crashes into the runway because they think they are higher than they really are, but the runway lights are never turned on. I'm no pilot, but I don't think a pilot would try to land a plane on an unlit runway.
Corrected entry: Forget BWI, why couldn't they just light up the runway with gasoline in the beginning?
