Of all the reports filed by the FBI, which do people want to read most? You might think it would be about John Dillinger or Roswell. But no. It's actually a file known as the Hottel memo, which dates back to March 22, 1950 and is only two paragraphs. The mysterious file, which was uploaded to the Vault (the FBI's online database accessible to anyone with an internet connection) in 2011, was viewed a million times in just two years. The memo was written by Guy Hottel, then head of the FBI's Washington field office. His report details an account supposedly given by an Air Force investigator who says he recovered a trio of flying saucers-with alien crew and all. The saucers were "circular in shape with raised centers, approximately 50 meters in diameter," according to the memo and "[The aliens had] bodies of human shape but only 3 feet tall, dressed in metallic cloth of a very fine texture. Each body was bandaged in a manner similar to the blackout suits used by speed fliers and test pilots."
Of all the files available in the FBI's online database, the most-viewed is a two-paragraph note from 1950 called the Hottel memo, and some say it proves the existence of UFOs.
