Revealing: When the co-pilot gets sucked out of the plane, it's obviously a dummy.

Factual error: The scene where the Cessna hits the Boeing 747 in flight plumbs new depths in cinematic absurdity. Assuming both aircraft are at their normal cruising speeds - they appear to be - and the Cessna has half a fuel load left, it will hit with the same energy as 17000lbs of TNT. Even a glancing blow would tear the entire front half of the 747 to bits - there would be virtually nothing of the fuselage left intact all the way back to the wings.

Continuity: 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: On the interior shots the pilot is struggling and on the exterior shots he is flying calmly.

Factual error: The 747 takes off from Washington D.C., while there's still some daylight, toward the west coast. Due to complications it's diverted to land in Salt Lake City. The Sun goes down and the plane is shown flying all night long. The Sun even comes back up before they get to Salt Lake. Really, how could it take that long for a jumbo jet to fly a measly couple of thousand miles?

Continuity: 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: 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: 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.

Plot hole: A Boeing 747 is about to (potentially) crash land (at the end of the film). As many emergency vehicles as possible would be on standby, yet all that's present is one ambulance, waiting to rush a child to hospital for a kidney transplant.
