The Disclousure Project are pretty sure there is something fishy going on at Area 51. I guess if there was anything fishy going on, that place would probably be implicated in some way. Some of the things caught on tape flying round out there perform some amazing/impossible manuvers, and look exactly like common or garden UFOs.
There are lots of secret bases all over the US, such as Mount Weather in Virginia, which is inside a granite mountain, said to be where Dick Cheney is skulking around when he's at 'an undisclosed location.'
So the story goes, just to the south of Area 51's Groom Lake facility is allegedly a smaller base cut into the mountains, hiodden from sateelites, with 9 hangars, and four underground levels, known as S4. That's where many have claimed recovered UFOs/alien bodies in jars are stored. A guy called Bob Lazar claims he worked there, although he was discredtied, he and a very weird guy called Dan Burisch, who says he was part of a secret project called Majestic 12 (or MJ-12) and has been working side by side with grey aliens there for years and bangs on a lot about 2012. Again, not a shred of proof, likely a load of rubbish.
