Audio problem: When Mike is being attacked by a bat in the cabin, after David puts the cover over his head, you hear a glass break. That was supposedly the shelf behind him, yet there was no glass on it.
Audio problem: The last scene begins with Al and Mike walking towards the plane speaking. Al asks "are you sure you don't want a job on my staff?" Mike then responds by stating; "you know what Al... I don't really think I'm cut out for politics." Al then is heard laughing at this. It is very clear the audio laugh is actually that of actor David Spade and appears to be placed over a most likely silent smile of Al. (01:20:00)
Answer: Chris Farley weighed over 300 pounds. His jacket would have torn long before the plane took off.
