The footage combines still images and motion-control camera shots sourced from the published Roswell Report, as well as various magazines and books about UFOs. 

It opens with a shot of the book 'The Roswell Report: Fact Versus Fiction in the New Mexico Desert' and ends with a stark black-and-white image that appears to show a crash site, with debris scattered across a massive crater in the ground.

The video has flooded the internet, with users claiming the crater bears a striking resemblance to eyewitness reports, suggesting it could be 'the first pictures of the 1947 UFO crash site.'

Major Jesse Marcel, who recovered debris from the crash, described the scene as 'a large area heavily scattered with metallic debris from a single impact point that scarred the earth.' 

Some viewers have also pointed to a dark formation on the right side of the image, claiming it resembles an alien body. 

UFO expert Mark Lee told the Daily Mail that the crater image was likely included to add intrigue. 

'In my opinion, it's either a hoax,' he said. 'Just because it's been added to the National Archives doesn't give it scientific validation. If it came out as a release from the military or Congress, I would take it a lot more seriously.'

Lee also noted that the 'alien' in the photo is nothing more than a case of pareidolia, a psychological response to seeing faces and other significant and everyday items in random stimuli.

The newly uploaded video appears to focus on 'The Roswell Report: Fact Versus Fiction in the New Mexico Desert,' a 1995 book that attributes the crashed 'UFO' debris to Project Mogul.

Project Mogul was a top-secret US military program from 1947 to 1949 that used high-altitude balloons equipped with microphones to detect sound waves from Soviet atomic bomb tests. 

A 1994 military investigation concluded that the debris found at the Roswell site was likely pieces of a high-altitude balloon from Project Mogul, not an extraterrestrial spacecraft. 

Despite this official explanation, the newly uploaded video has sparked debate online, with viewers offering widely differing interpretations.
