Revealing mistake: When the plane approaches the aircraft carrier, they have to dump fuel, and the fuel comes out through the back. However it should be coming out on the wing tips. So they had a tank of water or something similar that they sprayed out through the back. (Confirmed by a Staff Seargent with the USMC who flew 8 years on a C130.)
Revealing mistake: Mitch is carrying a doll during the chase on foot – it's way too floppy to be an actual person.
