Visible crew/equipment: When we first see McClane on the snowmobile, marks from the camera snowmobile are visible. (01:27:20)
Visible crew/equipment: When we first go to the Annex Skywalk, the SWAT team are walking with the guy from the tower and he is talking on a radio. In the mirror behind them you can see the boom mike and operator as they walk.
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.
John McClane: Hey Carmine, let me ask you a question. When you go through the airport metal detector, what sets it off first? The lead in your ass or the shit in your brains?
Trivia: The film is based on a book called "58 Minutes" by Walter Wager. In the book, it is the hero's young daughter, not his wife, that is on one of the planes.
Answer: In the first movie he's a New York cop visiting his wife. In the second Die Hard, he tells the airport officer that he's LAPD and moved there because of his wife's job. In the third Die Hard film, he most likely went back to New York because of marital problems and became a New York cop again.
