FBI records on UFOs including Washington-area incidents

The FBI has released declassified files through its FOIA 'The Vault' that include memoranda and investigative notes about UFO reports, including references to the July 1952 Washington, D.C. sightings and related inquiries. Those records were produced by the FBI’s offices in Washington and are accessible online from the FBI's public records. The FBI building in Washington houses the agency that compiled and later released those documents.
