Roswell has been at the heart of the UFO scene since July 1947 when the military sensationally announced in a press release it had found the remains of a crashed flying saucer in the desert nearby.
But the following day it retracted the statement, saying it was in fact a damaged US Air Force air balloon.
Witnesses later came forward to say there had been alien bodies within the “crashed craft”, which along with the wreckage were then taken to a top-secret military base.
It has remained the most infamous UFO conspiracy theory ever since.
But now a new book has put forward a theory that is claimed could solve the world’s biggest ever UFO mystery once and for all.
British UFO and paranormal investigator Nick Redfern suggests that the object that crashed may have been a top-secret experimental craft with human guinea pigs on it who perished.
In the book, The Roswell UFO Conspiracy – Exposing A Shocking And Sinister Secret, he claims the UFO myth was pedalled by the US Government to cover up the real horrific truth.
Refern’s theory comes from an interview he conducted in 2001 while investigating Roswell.
He met with an elderly woman, who claimed to have worked at Oak Ridge National Laboratory in Oak Ridge, Tennessee.
She claimed that shortly after the Second World War, she saw “human guinea pigs” including the Japanese, handicapped people, and prisoners.
She told of them being involved in experiments with new aircraft.
Redfern discussed the theory on Coast to Coast radio in the US.
Host George Noory said: “Through her testimony, and other witnesses he’s spoken with in the ensuing years, Redfern has pieced together that the so-called aliens found in the Roswell crash, were likely these humans deemed expendable by the government, who were used to test out the rigours of high altitude exposure.”
According to the book, the experiments reportedly used technologies brought over from Japan and Germany using gigantic balloons with attached gondolas that contained the test victims.
Mr Noory added: “The cause of the night flight disaster in July, 1947 may have been that the balloon collided with the craft that was accompanying it, which led to the balloon exploding and raining down a large amount of tin foil-like debris over Mac Brazel’s ranch.”
Mr Brazel had previously said he saw two balloons come down on his ranch.
People have said that hieroglyphics were seen on some parts of the wreckage, and Redfern says it may just have been Japanese writing.
Alejandro Rojas, host of Open Minds Radio, who also interviewed Mr Redfern, said: “This theory is highly controversial among UFO researchers.”
