Another explanation is that George  Reeves "body pan was attached to a pole that was blocked from view  by his body. Unfortunately it was attached on only on his right  side. If he had to be shown flying in the opposite direction the  film had to be reversed. This not only occurred in the colour  episodes, but the black and white ones as well.
