Apollo 14 Astronaut, Edgar Mitchell, Ph.D., sixth man to walk on moon
Yes, there have been ET visitations. There have been crashed craft. There have been material and bodies recovered. There has been a certain amount of reverse engineering that has allowed some of these craft, or some components, to be duplicated. And there is some group of people that may or may not be associated with government at this point, but certainly were at one time, that have this knowledge. They have been attempting to conceal this knowledge or not permit it to be widely disseminated. ... People in high level government have very, very little, if any, valid information about this. Most have no more knowledge than the man in the street. ... [As to] the question, "How could it be kept secret?" It hasn't been kept secret. It's been there all along. But it has been the subject of disinformation in order to deflect attention and create confusion so the truth doesn't come out. ... I believe it is a very important effort that we get Congressional oversight of all. HERE IS A LINK TO WATCH THAT IS INTERESTING

We may have Tang thanks to the space program, but who gave us such innovations as the Stealth fighter and Kevlar? Aliens, of course. Conspiracy theorists believe that the remains of crashed UFO spacecrafts are stored at Area 51, an Air Force base about 150 miles from Las Vegas, where government scientists reverse-engineer the aliens' highly advanced technology. Fodder for this has come from a variety of supposed UFO sightings in the area and testimony from a retired Army colonel who says he was given access to extraterrestrial materials gathered from an alien spacecraft that crashed in Roswell, N.M. Some believe that the government studies time travel at Area 51, also known as Groom Lake or Dreamland.
The government has developed advanced aircraft and weapons systems at nearby Nellis Air Force Base, including Stealth bombers and reconnaissance planes. And the government's official line — that the details of Area 51 are classified for purposes of national security — is only seen as further proof that the military is hiding aliens or alien spacecraft.
