UFO investigators launched a top-level probe into claims two men were abducted by aliens in the Capital.
The legendary story told by Garry Wood and Colin Wright, who said they were examined by extraterrestrials after their van was ambushed by a flying saucer, is being turned into a film starring Billy Boyd.
But rather than being dismissed at the time as Hollywood fantasy, the 1992 incident was taken seriously enough to be investigated by the Ministry of Defence.
Garry, then a 33-year-old ambulance technician from Edinburgh, was driving a car to Tarbrax, South Lanarkshire, accompanied by Colin, 25.
The classified documents – released today – state that Garry “was driving along the A70 when the object dropped a curtain of white light in front of the car”.
The report continued: “His friend blacked out for what seemed like 10-15 seconds. He thought he had died. When he woke up the car was facing the other direction on the wrong side of the road. When he checked his watch he had lost about one hour.”
It describes the UFO as being 20 feet high and 30 feet wide, and black with no lights, and tells how the claims were reported to police, a doctor, a psychologist and a university.
Shortly after the incident, the pair visited paranormal investigator Malcolm Robinson, who convinced them to undergo hypnotic therapy, which was said to have revealed that the aliens experimented on the men.
Mr Robinson, who helped write A70 – the film based on the claims which will be released later this year – said the terms of the movie deal banned Garry from talking about the MoD report.
But speaking in 1996, Garry said: “I saw three creatures coming towards my car. I felt intense pain, like an electric shock. Then I was in some room. I saw these things like wee men moving about, doing something to me. Then this six-foot creature approached.
“It was white-grey in colour with a large head and dark eyes with a long, slender neck, very slim shoulders and waist.
“The little ones were about three feet tall and seemed to do all the work while the big ones did the communication.”
He said one of the aliens spoke to him and said: “Sanctuary – we are here already and we are coming here.”
Mr Wood also claimed that a red-hot, poker-like object was put into his eye, and he was surrounded by other crying humans.
The classified documents also reveal how an air crew on a flight from Aberdeen to Edinburgh reported seeing, from their cockpit, a “bright light” rising through the air in December 1996.
Meanwhile, George Foulkes, then a Labour MP, asked about the US Air Force’s Aurora project for a high-speed aircraft in the early 1990s, following reports of unidentified high-speed radar contacts around RAF Machrihanish in Kintyre. He was told the matter was an issue for the US authorities.
