We Have All Heard About It,

and a few of us have read about it,

but what exactly is Area 51 in Nevada? it is legendary for its secret research on captured UFOs and the aliens they contain, the legend grew because the government wouldn't explain the classified aviation research going on there, the area was set aside for the development of the U2 spy plane in the 1950s, U-2 testing began in July 1955, and immediately reports came flooding in about unidentified flying object sightings, many of these sightings were observed by commercial airline pilots who had never seen an aircraft fly at such high altitudes as the U-2, 

 whereas today's airliners can soar as high as 45,000 feet, in the mid-1950s airlines flew at altitudes between 10,000 and 20,000 feet, known military aircraft could get to 40,000 feet, and some believed manned flight couldn't go any higher than that, the U-2, flying at altitudes in excess of 60,000 feet, would've looked completely alien, 

for a full rundown on what goes on in area 51 here is the complete lowdown on what goes on there, or is this story yet another cover-up as Bob Lazar claimed to have seen alien spacecraft there so many years ago, but at least the US government now admits it's, that is Area 51's existence, well both Bill Clinton and Barack Obama made mention of the area in the video clip, so it must be true, Area 51 is really there, regrettably neither mentioned the aliens or their spacecraft, as an aside if you think that Area 51 is mysterious, 

 how about this, the even more unknown base situated in the place known as Area 6, above the runway in Area 6,

and the hangers and service buildings, 12 or so miles away from Area 51, what secret aliens and spacecraft do they hold? cue music from the X-Files.
