Deliberate mistake: In a lot of the shots in the cockpit, when Teri is attempting to begin taking control of the aircraft, notice the Horizontal Situation Indicator on the First Officer's side. The compass rose is moving around erratically - which would suggest that the 747 is also changing heading extremely erratically and robotically - which isn't possible.
Turbulence (1997)
1 deliberate mistake - chronological order
Directed by: Robert Butler
Starring: Ray Liotta, Brendan Gleeson, Hector Elizondo, Lauren Holly
Continuity mistake: When the fighter shoots and blows up the truck, there is a shot of the flight attendant (at that moment being strangled by Ray Liotta) sitting in the pilot's seat, looking over her shoulder. It cuts back to the pilot, then back to her being strangled again. Very, very choppy editing.
Lt. Aldo Hines: Here's who you're dealing with: male Caucasian, 35, well educated, raised by his aunt who mysteriously disappeared when he was 16, has raped and strangled five women, escaped when being transported to San Quentin.
