A CIA scientist thought the fake alien autopsy from the famous Roswell UFO crash was actually real, a bizarre leaked memo claims.

The 2001 document has electrified UFO hunters who believe the footage, apparently showing a dead alien after the Roswell UFO crash in 1947 being dissected by medics, was not faked after all.

The strange film footage was released to the world by Brit entrepreneur Ray Santilli, who claimed he obtained it in 1992 from a retired US military cameraman while seeking archive footage of Elvis Presley in the US.

He went on to sell the footage to TV stations in 33 countries - before fellow film maker Spyros Melaris revealed last year that they had actually faked the footage using animal organs and pig brains in a London flat - and managed to fool the world for a decade.

But the story has taken a new twist after a leaked memo was allegedly sent to aerospace billionaire Robert Bigelow from one of his physicists Eric Davis.

It claims former CIA scientist Kit Green was "briefed three different times during and after his tenure at CIA on topics relevant to UFOs and the Roswell Incident Alien Autopsy”.

The memo, believed to have been leaked from the archives of late astronaut Edgar Mitchell, states: "After Kit left the CIA he was called into the Pentagon by a person in uniform.

"This person showed Kit the alien autopsy photos and reports etc. The photos of the alien cadaver Kit saw were consistent with the cadaver seen in the 1995 Santilli film/video.

"Kit was asked to professional evaluate the material provided to him at this particular briefing."

Green provided his professional evaluation of the footage in January 2001, according to the leaked document.

A summary of his evaluation stated: "The Alien Autopsy film/video is real, the alien cadaver is real, and the cadaver seen in the film/video is the same as the photos Kit saw at the 1987/88 Pentagon briefing."

The memo also includes an email in which Green reveals alien forensic tissue and organs were being stored at Walter Reed-Armed Forces Institute for Pathology Medical Museum in Washington DC.

When asked why there was so much debunking of the Santilli video when it first aired, Green said: "The PR folks around Santilli are indeed not operating with a full set of dishes, are a little dense and not very nice to boot."

The memo has re-ignited the heated debate over the footage both in the US and in Britain with a number of top UFO researchers now publicly backing the film, including Linda Moulton Howe, Richard Dolan and Grant Cameron.

Howe, an Emmy award winning documentary filmmaker, said on her Youtube Channel: "Those words from Dr Kit Green about the authenticity of the six-fingered, six-toed human dissected after retrieval from a 1947 UFO crash, it is confirmation that the Santilli film video is real. It is important."

However British UFO sleuth Philip Mantle, who has probed the footage for 14 years, has branded it the "world's largest hoax", although he believes the memo, which was emailed to him before appearing online, is genuine.

He said: "What amazed me is that I am personally mentioned in this 11-page document.

"It just goes to show that just when you think you’ve seen it all then something will crop up to prove otherwise.

"What has sent some UFO researchers into a tailspin is the comments from Kit Green in this 11-page memo.

"Dr Kit Green is best known in ufology for his work as a Senior Division Analyst for neurosciences at the CIA and his interest in UFOs.

"Green states that he had previously seen an authentic alien autopsy (some years before the Santilli film was released) and that it was the same as the alien autopsy film released by Ray Santilli in 1995.

"Those who have now jumped on the alien autopsy gravy train are Grant Cameron, Richard Dolan and Linda Moulton Howe.

"Of course, Kit Green could not have seen an alien autopsy film or photograph that looked the same as the Santilli alien autopsy film some years before as the Santilli film is a fake and was not made or conceived until 1995 when Spyros Melaris appeared on the scene.

"Spyros worked with UK sculptor John Humphreys to make the film. It really is that simple.

"Kit Green could not have seen what he claimed to have seen in the memo. I have tried to point this out to others, but I simply can’t get around their belief system."
