I listened to the whole thing, paid full attention, but I still don't really buy it. I agree that there's more to it than we know, but I don't agree with alien moon bases. It's like the 9/11 conspiracies... I agree that there's alot more to it than we know (WTC building #7 going down, wtf.), but I don't think the government did it.
It is very interesting, and I do really want to know why haven't gone back up there, or why nothing up in space has at least taken pictures of the dark side.
