Umm......... so who won? prehorusin04 or shadowborn?
And what if the only folks who knew it to be a hoax were the "astronauts", and a select handful of G-men, which would also exclude the Pres.? In a case like that, you only have maybe a dozen who are in the know, a more manageable number wouldn't you agree? (FFYI: I'm just playing Devil's Advocate here.)
The UN moves trains and such through our country unchecked now, in this age of information super-saturation. So, how much easier would it have been back in the '60's when people actually trusted the government? It would be much easier then to do those things and get away with it. The government built an entire small city in a mountain and it never leaked out till after the Cold War was over. To answer your question, yes, I believe it is quite possible that this could be a plausible scenario. As for the X-files stuff, who knows, maybe FEMA is the new shadow government, or whatever the in-term is right now.
the renting of stuff is something i could have done.Paper trails can be burned. and the only ones who knew what they were doing were the ones doing the conspiracy.astronomy specialists are exceedingly rare when outside nasa/nasa affiliates.
Buget equals really high. They could have built the stuff themselves and rented out a place which they or someone they knew owned under a fake or annonymous name. some people can be convinced and some could just disappear like some paper work. they have the money. and if the goverment was in it. then they defintely had the connections
