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.
## UNCLASSIFIED Once again, the report given is entirely inadequate for a conclusion. However, astronomical origin of the object or objects observed seems very improbable. The phenomenon described resonates the observation of an airplane beacon or search light reflecting against an overcast. This would certainly be periodic, appear phosphorescent, travel at great speed, and to oval in shape. Such interpretation would dismiss the occasional bursting and disintegrating as a subjective impression. However, weather conditions are not stated.
