Factual error: After the corvette escapes at the end, Darth Vader is standing at the edge of the hanger, and his cape is fluttering in the breeze. Only problem is they're in space, with no wind, or high enough that the atmosphere is so thin that there's no wind. Or there's a forcefield closing off the hanger from the outside, so no wind. And even if it's that air is rushing out of the ship due to the vacuum, his cape would be blowing towards the hole, not away from it. Plus the troopers behind him would all be asphyxiated - their suits aren't space suits.
