The Federal Bureau of Investigation (FBI) is the main U.S. domestic law enforcement and counterintelligence agency. During the 1947 flying saucer wave, Director J. Edgar Hoover agreed to help the Army Air Forces investigate reports, but he pulled the Bureau out within months, reportedly irritated that agents were being asked to chase hoaxes and that the military would not share recovered discs.
UFO files

The FBI's online Vault holds hundreds of pages of UFO material. They include the 1950 Guy Hottel memo, which repeats a third-hand story about saucers and small bodies in New Mexico, files on contactee groups watched for possible subversion, and the 1988 inquiry into the MJ-12 documents, which the Bureau's analysis treated as fake.
