Plot hole: In the Redstar mainframe, we are told that the floor of the vault will trigger the alarm if it receives more than 0.25 seconds of contact (apparently even with the security checks). What would be the point of the bosses going through all of those security measures if they would just set the alarm off anyway? Surely once the girls have faked the fingerprint and retina scans, they don't then need to flip across the floor! (00:33:55)
Plot hole: When the girls found Knox in the room, they had to break down the door because it was bolted from inside. Now wouldn't that be suspicious? He's in a room where the only way out is through a door that was bolted from the inside... (00:26:20)
Plot hole: When the Angels rescue Knox, why is the light swinging above his head? He's tied to a chair, the Creepy Thin Man's obviously not been through, because there's no exit aside from the bolted way in, so what's moved it? (00:26:20)
Plot hole: In the scene where Cameron Diaz is gaining entry to the Redstar mainframe, she wears a white suit to remain "undetected" in the antechamber. And then, she opens the door into a dark room, meaning that the security camera will spot the door opening if not the person opening it. Whats the point of wearing a white suit to hide from a camera, if the door opening will show up anyway? (00:41:10)
Suggested correction: Knox wasn't a trained pilot. Either he had no clue to what was going on, or he thought something may have been wrong, but didn't know what to do about it.
Taking off and landing a helicopter are by far the most intense and difficult part of a pilot's training. Seriously, 99% of learning to fly is learning how to land and take off. If the pilot is skilled enough to take off in a Huey he is easily skilled enough to notice a massive additional drag on his helicopter due to the additional weight of the angels and the air resistance put up by such a bulky protrusion on his aircraft. If he isn't skilled enough to notice that, he isn't skilled enough to take off in the first place.
