Astounding new footage of what appears to be an alien carried away on a stretcher after the Roswell crash has emerged.
Back in 1947, it was reported a UFO spaceship had crashed in Area 51.
Initially, the military appeared to confirm this before insisting a few days later it was just an armed forces balloon.
But now conspiracy theorists have claimed this new footage clearly shows what appears to be medical personnel seeming to carry the body of an alien away from the crash site.
The grainy images have been posted to YouTube with the caption Roswell UFO crash new footage of alien body.
The footage seems to show scientists gathered around the body, which has a humanoid appearance.
Since the infamous crash, there have been thousands of theories as to what really happened in Area 51.
In the 1990s the US military tried to quell some of the rumours by revealing the military balloon that had crashed was a nuclear test surveillance balloon from Project Mogul.
This was a top secret project that was designed to detect sound waves generated by Soviet Union atomic bomb tests.
The military wanted to hide the true nature of the project and so claimed it was nothing more than a weather balloon.
But 30 years after the incident, hundreds of documents emerged that seemed to have been written by people working within Area 51.
They claimed there was evidence that at least one alien spacecraft had crashed near Roswell in 1947.
Since then, there have been countless books written about the supposed alien landing and a number of films and TV series.
The Roswell myth also picked up steam back in 1995 when what appeared to be genuine footage of an alien body inside a huge glass container emerged.
The "leaked" video was later exposed as an elaborate hoax, but the footage had reignited interest in what had happened on that day in 1947.
Spyros Melaris made the black and white film showing men in white coats apparently dissecting the alien.
Millions of people across the world watched the footage, but Melaris has always insisted the 17-minute clip was nothing more than a hoax filmed in a north London flat.
And the myth refuses to die with a new Netflix documentary claiming to lift the lid on the Roswell conspiracy.
Unacknowledged insists it has unearthed fresh evidence to suggest the military DID cover up what really happened.
