There is a romour that at the lower excavated levels of area 51,most of the world's greatest minds live and perform genetic engineering experiments purely for military purposes,they work for an organization called majestic 5
It hasn't yet been proven that there are alien crafts in the hangars of area 51, but I believe they were either working with highly dangerous chemicals, or doing human tests with these chemicals. Or something to that extent.
Not only is area 51 a real place I, myself, visited it and, although we were some 30 yards away from the fence, military security came directly to us and confiscated a digital camera we had. We never saw anything unusual but that didn't matter.Either the place does have what rumors say it has, or had, or its a red herring created by government disinformation.
It's exposed to be, and most likely is, a place to test new equipment, especially aircraft. Being in the middle of a giant desert it's a good place to test aircraft so no one can see and if they go down their probably easier to find and won't crash into anything. If the government does have access to known extraterrestrials or technology (which is doubtful they could keep it covered up so long, a report or something would have leaked by now by a disgruntled employee or politician), I'd highly doubt they'd be located in a place known for houseing them.
It's the place where the USA government keeps the aliens but that's a n national secret everyone knows it egsists and none knows where but i don't belive in it
