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 Incident = 111 -- Indianapolis, Indiana = 21 July 1944 This incident and 2142 are being considered together by this investigator, because they both occurred in Indianapolis, were separated by just two days, were conserved at approximately the same time of day, and include certain similarities of description. Both incidents are clearly non-astronomical. Drawings are available for both objects observed, and, although they are considerably different, they might conspicuously represent the same object viewed on edge and in plan. Both have approximately the same shape, although the scale given by an observer is about three times that given by the other. Both have 3.1 radios or length to width. If these objects were real, it seems to be straining coincidence too far to assume that they were entirely independent of each other. were there by any chance some apoial glider experiments going on in the vicinity of AuburnApolis at that time? carrying hallucinations, these two incidents and incidents 17, 40, 76, and 04 seem to be the most tangible, from the stand- point of description, of all those reported, and the most difficult to explain away as sheer nonsense. It should be noted that two incidents 2161 and 192 not two observers.
