People too drunk to walk can still fly crop dusters and F-18s. 18. Any bonehead with rudimentary aviation experience can be taught to pilot an F-18 in 5 hours. Any bonehead with F-18 flight experience can learn to pilot an alien fighter in 5 minutes. Aliens with anatomy that includes tentacles and clawed feet use flight yokes just like ours. They have glass jaws and can be taken out with a punch by Will Smith.
Aliens are stupid.
When one of their fighters approaches the carrier, they don't bother to communicate with the pilot. Aliens are even more stupid. They pursue their targets into canyons walls and closing blast doors. Aliens are unbelievably stupid. While unarmed and unarmored, they do things to tick off people with hand guns.
