Sergeant Slaughter: When I'm through, scuzzbucket, they're gona scrape you off the wall with a squeegee!
In the opening battle sequence, Cobra Commander takes a bomb and sets it for 3:00 minutes. As he flies with his jet pack to the Statue of Liberty, it counts down to 2:58. He lands and places the bomb, and laser blasts hit all around him before he turns and flies off. This takes about 5 seconds to do, but the timer on the bomb stays at 2:58 for the full time of him landing, placing the bomb, and flying away.
After the opening battle, the Cobra base is shown. Several flying fighters emerge from it and fly off. The sound effects of these are blatantly pulled from the snow speeders in the Battle of Hoth in Empire Strikes Back.
