About The Flying Saucer Files

Project Blue Book was one of a series of systematic studies of unidentified flying objects (UFOs) conducted by the United States Air Force. It began in 1952 and was terminated in December 1969.

Two of the program's goals were to determine if UFOs were a threat to national security, and to scientifically analyze UFO-related data. A total of 10,807 UFO reports were collected, analyzed and filed.

The project's records were declassified and released to the public through the National Archives. This archive makes those records searchable and accessible.
