This Project Blue Book case file covers the 7 January 1948 incident at Godman Field, Fort Knox, Kentucky, which the file itself calls the famous "Mantell case." It holds control tower witness statements describing a large, bright object and the three P-51s sent to pursue it, whose flight leader, Mantell, stopped answering after climbing past 15,000 feet. It also includes weather data and Air Materiel Command correspondence. One analysis concludes that the object was not Venus and that the sighting must be considered unexplained.
