Errores

In the final scene Farid is somehow handcuffed behind his back even though one hand was amputated earlier in the film.

It has been stated that when he bends over to check on Elias you can clearly see two hands. However, if look closely you can see that he doesn't have two hands because His left hand is still missing. What at first might look like a hand the scrunched up end of his sleeve and tie wraps.

The aircraft used in the film has four engines, while the control panel in the cockpit has control systems for an aircraft with two engines.

At 1 min 45 secs, after the helicopter has landed, the sergeant salutes the colonel. He returns the salute. Members of the British Armed forces do not give or return salutes when not wearing headdress.

In the end, after Elias has blown the plane up, Farid runs up to him, saying he's with the boy. The colonel asks his men to open his handcuffs, as Farid had both his hands cuffed behind his back, but Nadja cut Farid's left hand after he was bitten by Eightball, which meant that Farid had his hands behind himself all this time in goodwill as he could have slipped out his left hand out from the cuff at any time.

In the beginning, the aircraft's engines turn off as soon as the plane comes to a halt, even though the controller has just instructed Farid to use the brakes.

The commercial airliner does not have an ID number on its tail wing.

Dominic Purcell (Berg) lets his real Australian accent slips through as he's demanding that Nadja open the cockpit door.

The cargo fire sprinkler system is somehow able to put out a fire which is contained 'inside' a vehicle - and thus, under the roof.

When the plane comes to a standstill, it is on the runway. When it 1s blown up and burning, it is not on a runway.

The hijackers whole plan is to jump out of the aircraft while it is at cruising altitude and speed. However, it is impractical and dangerous to parachute from a commercial airline which flies at 35,000 feet. The hijackers would not survive such an attempt even if they were fully trained.

However, it's impractical and dangerous to hijack a commercial airplane with three sky armed sky marshals aboard, yet they still do it. They believed they would survive, just like they believed they'd take control of the plane, that's all that matters for this not be a plot hole.
