Over a full minute passes from the time the plane is shown leaving the ground to when the pilots are advised they must stay below 1,300ft- their autopilot control panel shows an indicated altitude of under 900ft. A 747-8 would be likely be around 2,000-2,500ft at this point on climbout.

Though on takeoff the plane is shown as a Boeing 737, it is a Boeing 747 for the remainder of the film. The interior cabin of the plane is shown to be a coach section and first class, in a narrow body configuration. This would be correct for the 737, but not for a much larger 747.

Numerous characters refer to the jets escorting the hero plane as 'F-16s', despite an F-16 only appearing in one shot- preparing for takeoff in a mountainous environment that looks like Nellis AFB in Nevada. The planes used as escorts are F-18 fighters which are used by the US Navy, not the Air Force.

Despite the hero plane being a Boeing 747, most shots of the flight deck and of flight instruments are those of a Boeing 737. One shot shows two display screens mounted in a brown panel, which would be correct for the 747. Near the end of the film, a hand is shown adjusting the thrust levers, but these are from a twin-engine Airbus.

Despite the cockpit windows being riddled with gunfire and a heroic ex-army soldier tossing luggage from a cargo hatch mid-flight (an impossibility in its own right), the plane maintains pressure and the passengers do not seem disturbed at all.

Bomb bag was cut by knife to prevent triggering the bomb by opening the bag zipper. But clearly the zipper in shown open in very next shot.
