US flags still up and waving on the moon

Well, perhaps not waving.  As there's no atmosphere I'm pretty sure you can't have any wind.  Just googled - who knew, this is part of the whole Capricorn One conspiracy thing:

On July 20, 1969, two Apollo 11 astronauts planted an American flag on the surface of the moon. The flag was a standard 3-foot-by-5-foot nylon flag that was altered by sewing a hem along the top. A telescoping crossbar, hinged to the flagpole, was extended through this hem so that when the flag was planted on the Moon, it would stand out instead of hanging limp against the flagpole (as it would normally do, since there is no wind on the Moon). When the flag was planted, astronauts Neil Armstrong and Buzz Aldrin had a little trouble getting the telescoping crossbar to extend to its full length, and so it ended up being a little shorter than it should have been. As a result, the flag was bunched up slightly and looked like it was actually "waving in the breeze."
