Yes they did. From BadAstronomy.com (see below)Bad: When the astronauts are assembling the American flag, the flag waves. Kaysing says this must have been from an errant breeze on the set. A flag wouldn't wave in a vacuum.Good: Of course a flag can wave in a vacuum. In the shot of the astronaut and the flag, the astronaut is rotating the pole on which the flag is mounted, trying to get it to stay up. The flag is mounted on one side on the pole, and along the top by another pole that sticks out to the side. In a vacuum or not, when you whip around the vertical pole, the flag will ``wave'', since it is attached at the top. The top will move first, then the cloth will follow along in a wave that moves down. This isn't air that is moving the flag, it's the cloth itself.The moon hoax is a myth propagated by con artists that want to sell books.
