Mr. Switzer claims it's the engine on the left side of the aircraft (engine #1) that flamed out on final approach. The plane crash re-enactment also shows the plane veering towards the left, a normal reaction to a left engine flame out. However, all subsequent reports and even Greg, on the cockpit voice recorder, mention that it's engine #2 (right side) that flamed out.
Flight 1501 is a McDonnell Douglas DC-9 Series aircraft in all scenes, except on take-off, when it becomes a Boeing 727 instead.
When Scott shows Dianne the re-enactment of the plane crash the first time, there is no arrow behind the tail, indicating the position of the rudder. The arrow only appears immediately after Scott rewinds the videotape and plays it back.
When the pilot's wife returns home after his death, the answering machine shows 1 message waiting. When she hits the play button 2 messages play.
The plane crashed during a thunderstorm, but when the rescue trucks arrive at the scene, it is not raining and the ground is dry.
The fire trucks are spraying foam on airplane parts that are not on fire.
The day after the crash, body bags are still laying around the crash sight.
The air-plane seen is a McDonnell Douglas DC-9 from fictional airline 'CON-WEST' yet while in flight during the fierce thunderstorms you can clearly see a TWA (Trans World Airlines) on the tail-fin.
