GETTY In 1990 images emerged of a "secret US military alien autopsy" which was found to be hoaxed

An FBI memo that has come under scrutiny following freedom of information requests even suggests each "saucer" contained three bodies of three-foot tall aliens in the legendary "alien" incident. The Roswell incident, in July 1947, went down in UFO folklore after the US Air Force announced it had found the remains of what was suspected of being a crashed flying saucer in the New Mexico desert near the town. The next day it retracted the statement amid claims it was later identified as a weather balloon. UFO chasers have forever since believed it was a major cover-up and that the US military actually discovered the craft and the bodies of alien pilots. The FBI memo now in the spotlight, dated from 1950 - three years after the Roswell incident - said each of three "saucers" contained three bodies of three-foot tall humanoid occupants, making nine aliens in total. Museum workers stumbled across the document as as they were preparing to open the Hakui Centre for UFO Research in the coastal city of Hakui, 310 miles west of Tokyo, Japan, back in 1994.

But it has only come to light again after subsequent documents released under the US Freedom of Information Act suggested the FBI was so concerned about the museum opening, it opened up its own file on the proposals. The original 1950 memo suggested the US military found three metallic, saucer-shaped objects, complete with occupants, near New Mexico, in the USA. The memo revealed US radar equipment in the area was believed to "have interfered with the saucers and brought them down", according to the Journal Telegraph. It said: "An investigator for the Air Forces states that three so-called flying saucers had been recovered in New Mexico. "They were described as being circular in shape with raised centres, approximately 50 feet in diameter. "Each one was occupied by three bodies of human shape but only three-feet tall, dressed in metallic cloth of a very fine texture." The memo was sent by Federal special agent Guy Hottel, who was in charge of the FBI Washington Field Office, on March 22, 1950, to then FBI Director J Edgar Hoover.

The single-page memo begins with the name of the person who furnished the information about the flying saucers blackened out. It said: "According to Mr (blackened out) informant, the saucers were found in New Mexico due to the fact that the Government has a very high-powered radar set-up in that area and it is believed the radar interferes with the controlling mechanism of the saucers. "No further evaluation was attempted by SA [blackened out] concerning the above." The document was among 10,000 reports museum staff has obtained and were preparing to allowed UFO researchers access to via the planned Hakui Centre. But subsequent FBI papers dated from 1994 and now released under freedom of information requests, show the agency was apparently so concerned about what else may be contained within the files, it began monitoring the planned opening of the museum in 1994. This further revelation has sent modern-day conspiracy theorists into overdrive, who now believe there has been a major US government cover up over contact with aliens over several years. The FBI raised its concerns about the Hakui project in one memo dated January 7 1994, soon before the centre opened, saying the “main attraction” would be the library with the 10,000 documents available to read. The bullet point memo states that the museum official, Toru Wada, said, “In the future, we hope the center will become a focus of international attention in terms of collecting and disseminating information on UFOS.”
