Factual error: During the final fight, Liam Neeson jumps down an aisle to pick up the pistol that is hurled from the floor upwards in the air and shoots the villain in the head. The problem here is with physics. The plane was in radical descent moments before. The pilot eventually brings up the nose. At that moment, the gun and Liam Neeson himself would have been pinned to the floor.
Factual error: In a scene where Kat is flying to or from Northern California for college, in the background through the window on the plane one can see a commercial jet which has the winglets of a narrow-body Boeing, which were not introduced until 1998 on the Boeing 737 NextGen, rather than "wingtip fences" of an Airbus which were in use as early as 1985. Eve disappeared in 1988 when Kat was 17, so this would have been 1993 at the latest, when Kat would have been expected to have graduated from Berkeley. In the movie, it is suggested that this was just 2 years after her mother disappeared, so this would have been not later than 1990-91.nkeeshin
