Airport 1975 (1974)

Continuity mistake: The small plane's pilot identifies the aircraft as 232Z. But in the exterior shots, the aircraft's identification is N9750Y. (00:35:00)

Continuity mistake: Towards the end of the film and in the shot of the 747 as it turns to change course to Salt Lake City the company's name "Columbia" is printed on the aircraft's side on top of a large, white rectangle. After the aircraft comes to a stop on the tarmac the white rectangle is gone and the name is painted directly on its metallic fuselage.

Continuity mistake: When the Boeing plane is about to land we are shown an aerial view of the flying plane. You can see dirt on the (wind)screen of the plane, from which the scene has been filmed. As the camera turns from left to right, you can see the dirt pass by from right to left. This is not a plane which is escorting, because when the Boeing lands there is nothing else in the air.

Continuity mistake: The pilot that is flying the small plane has a plaid suit jacket on when shown from inside the cockpit. When shown from outside the plane he has a light coloured shirt on.

Continuity mistake: The pilot of the small plane that ultimately collides with the big airliner is speaking with the control tower on his radio. The identification numbers on the wings of the small airplane are not the same numbers that the pilot uses to identify his plane in his conversation with the controllers.

Continuity mistake: In the interior shots the pilot is struggling and in the exterior shots he is flying calmly.

Continuity mistake: As Murdock is being lowered toward the 747 there's a shot with a POV looking at the Plane's nose from some distance. It's an FX shot, a traveling matte of the actor with a large piece of airplane against a blue screen. The foreground & background elements don't match very well. The distant landscape below is moving linearly in one direction and the aircraft is pointing in quite another.
