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.
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.
