This case file comes from a series of sanitized case files on sightings of unidentified flying objects (UFOs) of Project Blue Book, the U.S. Air Force investigation into UFOs sighted between June 1947 and December 1969. The files contain the information the Air Force gathered about specific UFO sightings.
Each case file relates to one sighting or to a group of closely related sightings. The files contain reports from UFO observers, correspondence between these observers and the Air Force, newspaper and magazine clippings, and reports of analysis of photographs and physical evidence. Each case file contains a control sheet which summarizes the sighting report and shows the Air Force explanation and conclusions for the sighting.
