How was the American flag floating on the surface of the moon with the knowledge that there is no air?

It wasn't floating. It was held out by a rod sewn in along the top edge precisely because in a vacuum it won't wave or even stand out from the pole.

This question amazes me, because it is patently obvious from even a cursory examination of the film, photos and TV that there is such a rod in the flag, and yet people still ask how it was done.

There is a WIRE running through the top of the flags that holds the flags out from the flag poles because there is no atmosphere on the Moon.

Floating? It was swinging like a pendulum after the pole (which had an l-shaped extension rod) was moved. With no atmosphere to brake it, it could maintain such oscillation far longer than it could on Earth, and with a much more regular period.

It's not floating. There's wires threaded through it keeping it stiff. You know... seeing as there's no air/wind to make it flap. ;)

Uhhhhh.. Another government coverup?
