What is in the huge box the scanning crew brings to the flacon? I would think they would have a handheld device that can pick up life signs or droid that flys around. That box seems huge. It takes two men to carry and the stromtroops dont think it's odd that the scanning crew needs a hand in getting it out of the box.
Well, 1. it's a plot device to get Han and Luke into stormtrooper armor, and 2). they probably didn't expect capturing any ships like that, so it's not like the Imps had airport security ready to go at the time. Now that would be a nightmare.
I saw this thread and immediaterly thought of Masters of the universe where Skeletors minions are on Earth trying to find "the key" with that huge *** scanner
