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 13T -- realtis Covans 12° 05' 3, 100° 05' 2 -- May 1364 The object observed here was probably an exploding fireball even dead and even only at the time of actual explosion. This, with partial cloud coverage, could easily explain the absence of a trail. it is not likely that 11.1 he aligned on the water surface or aircraft aligned later and any relation to the original object. If the object had been a shell fired from the 20d laser, it appears improbable that only one shell would have been observed.
