Plot hole: When Rane and the other terrorists come out the bottom of the plane and start walking towards the fairgrounds, it is amazing how not one police officer or staff member of the airport notices that they came out from under the plane, or that they don't seem to be walking off the plane like the other passengers.
Continuity mistake: When Cutter is approaching the fence on the motorcycle, you can see a chain and lock around the middle. However, in shots from the other side of the fence, there is no chain seen around the middle.
Continuity mistake: When Cutter takes out the first terrorist in the bathroom, you can see the toilet seat is down (and the lid is up). When Cutter pushes him through the bathroom door, the seat and lid are both up. The seat is back down when the terrorist's head is dunked.
Revealing mistake: When Rane jumps out of the hospital window and crashes through the umbrella, table, and people, you can see him land on an air mattress. Even though it's camouflaged to match the ground, you see it deflate under his weight.
Continuity mistake: When the plane was getting ready to land at the small airfield, it passes over a small fair. When u see the police look up at the plane, its passing over a 2 wheel Ferris wheel while its moving. In the very next scene, the Ferris wheel is sitting still. It couldn't possibly stop that fast.
Suggested correction: The ferris wheel slows then stops, and the seats can be seen rocking back and forth from the momentum, exactly as they should. Ferris wheels do stop pretty quickly, especially when riders are getting on and off.
Continuity mistake: When Cutter enters the club for the luncheon meeting, you see him pull his hand out of his pocket, but in the next shot of him, his hand is back in his pocket.
Plot hole: When the police and FBI arrest Rane at the fairgrounds, Cutter tells them Vincent (one of Rane's men) is also at the fair, and wearing a tan jacket. Cutter did not see Vincent leave the plane and never saw him at the fair, and when he last saw him on the plane he was not wearing this jacket. So how could he know Vincent was at the fair and wearing a tan jacket?
Plot hole: The airport at which the plane lands is only supposed to have a small airfield. Yet near the end we see the huge plane roaring down the runway for more than a minute, which would be impossible on a small airfield.
Continuity mistake: When Cutter fights the hijacker near the bathroom door and puts a gun to his head, there is a shot of Rane and Liz Hurley arriving on the scene and behind them is the hijacker who wears glasses. But this hijacker does not appear in the following sequence, even though he was right there a second earlier.
Plot hole: Liz Hurley, who is one of the hijackers, learns that Cutter is an undercover security agent. Yet for some reason she fails to pass this on to any of the other hijackers. When they take over none of them appear to have any knowledge of Cutter.
Continuity mistake: After the main bad guy gets back into the plane, he goes to the cockpit and tells the pilot to take off. Look out of the window. The sun is obviously setting, then overhead in the very next shot under the plane. This whole sequence up to the point where the plane is in the air again features changing times of day.
Continuity mistake: After Rane escapes from the hospital he pushes a bearded man in a brown suit away. In the immediate wide angle the man has vanished.
Continuity mistake: When the plane takes off and Cutter is holding onto the landing gear, the sky swaps from daytime to pitch dark in a millisecond.
Plot hole: While Cutter is in the bathroom, the first thing he hears of the terrorists taking over the plane, is one of them yelling "sit down". If he heard that, how could he have not heard the gun shots when Ms. Ritchie shot the FBI agents, or the sounds of screaming passengers?
Visible crew/equipment: When Briggs hands Cutter his gun while they are chasing the plane in a patrol car, the camera and crew are reflected in Briggs' glasses.
Continuity mistake: When Cutter is in the bathroom with the phone, he opens the door slightly to check the situation. When he closes the door, the nearest terrorist standing about 10-15 metres away, hears the door shut and begins to approach the bathroom to investigate. Cutter opens the door again some 20 seconds later and the terrorist is still approaching. It should not have taken the terrorist this long to walk such a short distance.
