Conspiracy theorists claim a blurry letter seen in a picture could be the key to solving the Roswell UFO mystery.

The photo shows Air Force General Roger Ramey crouching over debris which was claimed to be from the Roswell Crash.

He appears to be holding a memo, which UFO researchers believe could be key in finally unlocking what happened in the New Mexico desert 70 years ago.

UFO researcher David Rudiak claims the letter makes reference to a wreck "victims"

David Rudiak, a UFO researcher, has used modern technology to zoom on the letter.

Alejandro Rojas, a presenter for Open Minds Radio, told Express Online: 'He [David] says it is clear that there is a reference to a disc and believes he can also make out a portion of a sentence that reads "and the victims of the wreck".

'Rudiak says this proves that a disc-shaped craft was recovered.

'However, perhaps more startling, he says it also corroborates the claims that extraterrestrial bodies were recovered from that wreck.'

The 1947 Roswell incident is one of the most controversial UFO episodes in history.

The military initially announce that a flying saucer had been found near the New Mexico town

However the statement was retracted and it was stated that a weather balloon had crashed

A weather balloon,used to monitor nuclear tests, allegedly crashed in the New Mexico desert.

However in a stunning development the military announced the next day that a crashed flying saucer had instead been found.

Roswell captured the public's imagination, and UFO enthusiasts have since flocked to the town

The statement was later retracted, but not before it helped fuel one of the biggest UFO conspiracy theories ever.

Researchers claim that the military covered up the UFO crash with the later story about the weather balloon.

Today Roswell is a magnet for tourists and UFO theorists, all looking for their own clues.
