Continuity mistake: The flight deck of the plane does not exist. It is a made up console that looks nothing like the one on the 747-200 (the plane shown in the air).
Other mistake: When Elizabeth (Catherine Bell) gives Merrick (Casper van Dien) the note with her phone number, we see that the number is 555-1234. But when he calls her, the number is 555-0199. (00:08:46)
Continuity mistake: The type of plane that Merrick is on varies between shots (Boeing 767 on the ground, Boeing 747-200 in the air etc.).
