Continuity mistake: When Dead Meat has crashed, and Washout's parachute is lying on the road, the ambulance runs over it. In the first shot, the ambulance clearly runs completely over it without catching the parachute at all. In the next shot we see the ambulance hooking the parachute and dragging Washout along the road.
Continuity mistake: When Adm. Tug Benson is talking to the troops, they're all acting out certain activities. It shows one man with a football, then cuts to Adm. Benson talking. When it cuts back to the men, the one who had the football is in the same position he was in earlier (as if he was throwing it), but no longer has the ball in his hand.
