When you see the janitor guy running towards the plane to stop it. The manager guy is drinking a cup of tea with the CCTV tv screens in front of him. The camera is positioned behind him....He takes a sip of his drink and whilst its rising to his mouth, he looks up at the screen. So the drink is fully up to his mouth.

Then in the next shot, the cameras facing towards him and the cup starts rising again and he again looks up. Whereas the cup should be fully up and he should already be looking at the screen! Not very good continuity if you ask me!

I noticed a bunch of continuity errors throughout the film. I was surprised at the end to find it was directed by Steven Spielberg!
