I’d go back with at least 3 friends, so one for each plane. I’d probably do more though. Then I’d stick each one on one of the planes, and hijack them ourselves. We would then land them at the nearest airport. We would also tie up the hijackers, and confiscate their box cutters. Then, just for fun, I would fly to New York and try to fly upside down between the towers.
If push comes to shove, we could always crash the planes into a field or something.
