Area 51 is actually near the the Nellis test range area, where we do Red Flag. The Groom Lake facilities are only a fraction of the area that is permanently off-limits; even military pilots who stray into their airspace will face disciplinary action. Area 51 is a military base, and is located in the southern portion of Nevada in the western United States, 83 miles (133 km) north-northwest of Las Vegas. Situated at its center, on the southern shore of Groom Lake, is a large military airfield. The base's primary purpose is undetermined; however, based on historical evidence, it appears to support development and testing of experimental aircraft and weapons systems. More info is found here: http://en.m.wikipedia.org/wiki/Area_51#section_3 . There is no independent confirmation that space aliens or alien technology is at this facility. However, the area was confirmed to be used to test many of our stealth airplanes.
Listen, Area 51 is real. I frickin' work for the people there. It's in Nevada..Fairly close to Death Valley. Of course, I'm sworn to secrecy and take my Oath seriously. All I'm saying is that the only time I went inside there- I'll never forget what I saw.
