Revealing: When everyone goes up to the second floor on the escalator, behind them outside through the glass doors you can see people walking about.

Continuity: There is a scene where Laurel, Dinah, and Toomey are in the Cloud 9 restaurant and everyone else is out by the windows looking at the plane. The camera cuts from the group out by the windows - which includes Gaffney - immediately to a shot of the Cloud 9 restaurant sign. You can see Gaffney inside the restaurant through the sign.

Visible crew/equipment: At the end of the movie, when the people stand against the wall as they return back to normal time, you can see tape markers on the floor, as they stand by the wall.

Continuity: In most scenes at Bangor airport the plane (L1011/Tristar) can be seen in the middle distance from the terminal window, but in one or two scenes it's right outside blocking the view.

Factual error: Attempting to steer an airplane moving along the ground at more than 100 knots will cause the landing gear to be destroyed.

Continuity: Towards the middle/end the mystery writer specifically says that on the airplane in Bangor there is electricity but in the airport there is none. However, when first arriving at the airport you can clearly see there are lights on overhead.

Continuity: Albert knocks Toomey out with a toaster. You can see during several subsequent shots that there is only a small amount of blood on Toomey's forehead and none at all on his face. Toomey lies there unconscious for a while, without changing position, and when he wakes up, suddenly his whole face is cut up and bloody.
