Audio problem: The pitch of an airliner's engine doesn't change dramatically when going through rough turbulence. In the scene with the turbulence - after all is quiet, it almost sounds as if the engines are shut down. And it happens way to fast for it to be the pilots doing it. And why would the pilots speed up when entering turbulence?
Audio problem: When the troops are lined up on the fort's wall near the end preparing for the waves of bugs, Lt.

Audio problem: When the Statue of Liberty's head strikes the top of a distant building before landing in the street, sight and sound are simultaneous. There should have been an audible lag in the sound due to the speed of sound being only about 1000 feet per second.
