Continuity mistake: Scott takes off his oxygen mask and stands up. During that brief moment the knot of his tie swaps from slightly loose to very loose.
Visible crew/equipment: When Milhouse puts on the Captain's jacket, the stage ceiling is seen.
Audio problem: Jennifer and the Captain exit the plane and stay there for several minutes while sirens from airport services howl, obviously to help them after such a chaotic flight. However, wider shots show that there's not a single car or person nearby.
Visible crew/equipment: After the dead couple are found in the toilet, two claws are seen wandering around, and beneath them two hands holding them.
Revealing mistake: At the end of the film, when the Captain says he's about to land, the exterior shot of the plane is the same image used at the beginning when the plane took off, only it's being played backwards, with the wheels coming out, and even worse, the tail of the plane is moving backwards.
Continuity mistake: By the end of the film, when the queen scorpion is wandering around, a shot of the floor shows that the plane is spotless, despite being filled with blood, paper, and debris a couple of scenes before.

Continuity mistake: Before the scorpion attacks the old man a jacket is hanging from a seat, but in a following shot it's gone.
Continuity mistake: Jennifer and the Captain crush the scorpion in the coffin. The first shot shows that only one tentacle comes out, but in the immediate close-up many tentacles are out.
Continuity mistake: The girl wakes up Jan when she sees the scorpion, but when the angle changes Jan is still asleep. Then back to the first angle and she is awake.
Continuity mistake: Jennifer is dressed up with the suit down in the cellar. When she runs toward the stairs she has reached them, but the following shot shows her back from where she started and she's running towards the stairs again.
Continuity mistake: The motorbikes chasing the van disappear from the wide shot after they throw the gas bomb inside.
Continuity mistake: The amount of people to the left of the security check, in the three seconds before and after Gunther passes by, differs drastically.

Continuity mistake: After the plane lands, an outside shot (stock footage) shows two male pilots in the cockpit, but inside there's only a man and a woman.

Continuity mistake: After crushing the scorpion in the coffin, the lid appears either well placed or slightly skewed, depending on the angle.
Continuity mistake: In the airport, the snobbish woman is seated close to the wall and the black man next to her. One second later she's sitting in a different place, holding a newspaper, and the Afro-American is gone.
Continuity mistake: The tentacle slaps the Captain on the cheek, but he appears wounded as if he had been hit across the eyes.
