Factual error: Leaving aside that it doesn't look like any real cockpit model, you can tell how fake it is when you look for the FMC, they used PC keypads. (00:09:27)
Factual error: During the final fight, Liam Neeson jumps down an aisle to pick up the pistol that is hurled from the floor upwards in the air and shoots the villain in the head. The problem here is with physics. The plane was in radical descent moments before. The pilot eventually brings up the nose. At that moment, the gun and Liam Neeson himself would have been pinned to the floor.
Factual error: Although the exterior and interior of the aircraft in the movie are reasonably accurate, the cockpit does not resemble any real life aircraft, let alone a 767. In actuality, the cockpit looks hilariously unrealistic for numerous reasons. It appears to be a bunch of random panels and pieces of other aircraft and their own designs all stuck together to form something that looks outrageously stupid. They even have a 4-engine throttle in there, even though it is a two engine plane.
Continuity mistake: Just after the captain's death, a close-up on Bill's watch shows its date as '11 07'. At all other times, it says '1 18'.
Other mistake: When Bill is walking into the airport after parking his car, the plane landing in the background is moving way too slow, revealing it to be a CGI plane.
Answer: This is an error. The fighter jets depicted could easily keep pace with an airliner without the need for afterburners. However, this very well could be an intentional error. The sight of afterburners gives the audience a sense of high speed which heightens tension.
