Not to mention with all the giant leaps they were taking on the moon, who is to say that they could not have fallen and smashed part of the helmet?

How could it have been safe to send men all that way with only one helmet each to keep their head in one piece?

It just doesnt add up. You just would not take risks like that.

It's just totally forseeable that something could go wrong. They were hammering this and jumping about like they had no care in the world. Who would have known they only had one helmet each and had to be careful not to smash it up or tear any part of those fragile space suits.
