FBI Compilation of Flying Disc Reports and Correspondence, July 1947

This document is a comprehensive compilation of Federal Bureau of Investigation (FBI) files regarding the 'flying disc' phenomenon during the summer of 1947. The collection includes internal memoranda, teletypes, correspondence from the public, and newspaper clippings. The reports originate from various locations across the United States, including Idaho, Wisconsin, Texas, Delaware, and California. A recurring theme throughout the documentation is the public's intense interest and anxiety regarding the sightings, often fueled by media coverage. Many reports describe circular, metallic objects, sometimes accompanied by mechanical components such as wires, coils, or radio tubes. Several specific incidents are detailed, including the case of Father Joseph Brasky in Grafton, Wisconsin, who reported a disc striking his church, which was later identified as a circular saw blade rigged with wires—a suspected prank. Other reports involve sightings by pilots, such as Kenneth Arnold, whose initial report of nine discs near Mt. Rainier is cited as a catalyst for the widespread public interest. The FBI's internal response was largely to avoid direct involvement, frequently instructing agents to refer such matters to the Army or Air Force, as the Bureau lacked jurisdiction and did not consider the phenomena a criminal matter. The documents also highlight the skepticism of scientific and military authorities, who often attributed the sightings to optical illusions, weather balloons, or mass hysteria. Despite the skepticism, the volume of reports necessitated a coordinated effort to manage information and maintain security, with the FBI acting as a clearinghouse for information shared with the War Department. The collection reflects the chaotic and uncertain atmosphere of the period, where the line between genuine unidentified aerial phenomena and human-made hoaxes or misinterpretations was frequently blurred.
