This August 1949 technical report from the US Air Force Air Materiel Command presents Project Grudge's investigation of unidentified flying objects through January 1949. Drawing on consultants including Dr. J. A. Hynek, Rand Corporation, the Air Weather Service and Dr. P. M. Fitts, it explains most of 244 incidents as balloons, aircraft, astronomical phenomena, hoaxes or psychological errors. It concludes the objects pose no direct threat to national security and recommends reducing the investigation in scope.
Incident g4J = g4J 2 altitude and asluth . Jr. shedes' camera was pointed at the time of his two exposures and the approximate time interval between exposures. Physical data like these are absolutely essential if we are to get anywhere in any basic physical explanation of these incidents. There remains the strong possibility that the entire in- oldest is spurious, and the invention of an exotic mind. This strengthens the need for reinvestigation; if spurious, this foot should be highlighted and even published, to quash enthusiasm for the irresponsible reporting of "saucers" and like objects.
