The Guy Hottel memo (FBI, 22 March 1950)
A one-page FBI memo of 22 March 1950 passing on, at second or third hand, an Air Force investigator's story of three saucers and their small occupants recovered in New Mexico, with radar named as the cause. It is the most-viewed file on the FBI Vault. The FBI never investigated the claim, and the memo names no source.
