The alien corpse at Roswell

The search for extraterrestrial intelligence is real, though we haven’t found them and (probably) they haven’t found us. But the fixation with UFOs and alien abductors reached new heights with the television screening of what is claimed to be a film of an autopsy on an alien that died when a flying saucer crashed in 1947 in Roswell, New Mexico.

In 1995, the US Committee for the Scientific Investigation of Claims of the Paranormal challenged almost everything about the black-and-white sequence — the age of the film, the photographer’s military status, the injuries to the alien and the way closeups of alien organs went out of focus.

"The film has all the earmarks of an obvious hoax," said an investigator.
