I do have one question/urban legend, to add to this discusssion.
That urban legend is that the unmanned Russian Lunig probe, which lifted of a wek before Appollo and crashed, out of control onto the moon a few days before the Eagle landed, WAS IN FACT NOT UNMANNED. It carrried a single cosmonault, who was meant to sing the Soviet anthem from the surface of the moon three days before Apollo landed.

Has anybody else heard of this one.
