Project Blue Book Roll 2: Case Files of Individual Sightings (File Nos. 55-179)

This document is a microfilm publication from the National Archives, specifically Roll 2 of Project Blue Book, covering individual sighting reports from July 9, 1947, to July 24, 1948. It contains a collection of case files, checklists, and intelligence summaries regarding Unidentified Aerial Phenomena (UAP). The records include reports from various military and civilian sources, such as the Newfoundland Constabulary, Pan American Airways, and various Air Force units. The document features evaluations by Dr. Hynek, who categorized sightings into astronomical, non-astronomical (balloons, aircraft, rockets), and those with no evident explanation. Several specific incidents are detailed, including sightings in Grand Falls, Newfoundland; Harmon Field; and various locations in the United States. The records also document the investigation of hoaxes, such as the 'flying saucer' found in Black River Falls, Wisconsin, which was identified as a plywood and cardboard construction. The document highlights the military's efforts to collect and analyze these reports, often coordinating with the Air Weather Service to rule out meteorological balloons. It also includes correspondence regarding the 'Mantell Case' and other high-profile sightings, reflecting the evolving methodology of the Air Force in investigating UAP reports during the early post-war period.
