Other mistake: When Alex Hopper is being tasered and arrested for robbing the convenience store, you can see his shirt is almost clean on his back. But he fell on the bottles and sodas rack in the store, the shirt should have stains.
Other mistake: The shot of the fleet outside of the barrier is reversed. The Aircraft carriers landing deck is slanted right instead of left. (01:15:00)
Other mistake: When they load the last shell to hit the island Hopper orders it to be taken from turret 3 to turret 2, but turret 3 is later seen firing.
Other mistake: Early in the movie, It is said in the movie that the force field is 300,000ft in altitude, and approximately 2 miles in diameter. It is far less than 300,000ft high, and larger than 2 miles wide.
Suggested correction: It's a non issue, it was a massive international naval exercise, Good chance of more than one carrier participating. In fact, every picture of an actual rimpac exercise has multiple carriers visible. Just because 1 carrier isn't in flight readiness mode doesn't mean that others aren't. Might explain why he ordered every plane in the air but there's what? Only 3 that actually save Mighty Mo.
True there may been more carriers but you are being attacked and invaded no flag officer would leave his deck cluttered they would be at battle stations for sure.
