sad but fascinating story!
I'm reluctant to bring this up as I know I'll get flamed even though I dont believe in the Moon landing conspiracy stories, but was there ever an official explanation why the flag is looking like it is waving in the wind?
What is complete FAIL is the idea that such an elaborate conspiracy would not have thought to hide the effects of wind, so the only explanation is: IT ISN'T WIND, DUMBASSES!
When I throw baseball, it keeps going until the resistance of the air slows it and gravity eventually brings it down. Without those, it will go on forever and will cause and equal force pushing the opposite direction on me. It's called momentum. You move a fabric in space and the momentum will cause it to curls and wave. It will look a bit funny because it isn't doing it through an atmosphere, and, well, as you can see, it does look a bit funny, exactly as you would expect. It will wave until it settles but the force has to be transmitted somewhere. Because there is no air to displace and move, it will swing until the gravity and friction at the contact points transfer all the energy (mostly heat).
Now, I could insult you for thinking that flexible sheets act like wood in space just because there is no air, but I won't.
