The most viewed file in the FBI's online Freedom of Information Act Library - also known as the Vault -is what some believe to be a real life X-File. Known in more paranoid circles as the 'Hottel Memo,' this officially filed UFO report has been accessed and viewed over a million times since it was uploaded in 2011.
The memo dates back to March of 1950 and is little more than a single page detailing a vague report about recovered UFOs. The memo was filed by FBI agent Guy Hottel. His report relays an account said to have been given by an Air Force investigator who claimed to have recovered a trio of flying saucers, with crew intact.
