mistakes on the movie
when idiot nr.2 jumps over to catch the bomb suitcase, he holds the gun in the hand (right hand), and catch the ladder of the plane while he still holds the gun. After 5 second, a frame in the movie shows him without the gun, he holds tight on the ladder with the right hand. The next frame shows him again with the gun in hand. This was one!
The second is: while he falls in the ocean, he holds the gun in right hand, the bomb suitcase in left hand. When he enters the water, the gun is in his left hand, the case in righ hand (btw, the movie pauses to show that time's up, 00:00)
