The American flag on the moon could be seen to "wave," which was thought to be caused by a sudden gust of wind. In reality, it is plainly obvious that the flag is being moved around by the astronauts as they twist the pole into the hard lunar surface.

From the first Apollo landing, astronauts commented on how difficult it was to insert the flag into the ground. They encountered very hard ground at about 9-11 inches, and had to twist the metal pole repeatedly to get it to seat in the surface properly.

We will never see the flag waving on the moon, because it never happened. The flag was on the airless Moon, just as we all knew all along.
