Project Grudge Incident Reports #41 and #47

This document contains a collection of materials related to Project Grudge, specifically focusing on incident reports and evaluations of Unidentified Aerial Phenomena (UAP). The file includes an 'Incident Index' featuring Dr. Hynek's evaluations, which categorize various sightings by probability of astronomical origin or other explanations such as balloons, rockets, or flares. A significant portion of the document details Incident #47, a sighting that occurred on 6 July 1947 at Fairfield-Suisun Air Base in California. The observer, Captain James H. Burniston of the USAF, reported seeing a single object at an altitude of 10,000 feet. The object, estimated to be the size of a C-54 aircraft, traveled in a southeasterly direction at a speed described as exceeding any known aircraft. During the 60-second observation, the object rolled from side to side three times, with one side reflecting sunlight strongly while the other did not. The report concludes that the incident cannot be readily explained astronomically, noting that while a meteor hypothesis is unlikely due to the duration and reflection characteristics, the possibility of subjective reporting remains. Additionally, the document contains information regarding Incident #41 in Anchorage, Alaska, on 11 July 1947, which was tentatively identified as a balloon, though data was considered too meager for a definitive conclusion. The file also includes various military communications, including teletype messages regarding sightings in Bakersfield, California, in July 1952, which describe a large, round, deep orange object. These communications emphasize that the object was not the moon and that no known air traffic was in the area at the time of the sightings.
