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 277 - South Brooksville, Maine - 3 July 1947 there is nothing to suggest an astronomical origin of the objects cited in this unusually self-reported incident. Inasmuch as the digitals were made by an "astronomer" (although this investigator has never board of him, one can presume that any astronomical implications would have been noted. The observer's question "Have any meteorites been reported?" is puzzling, because he should have been able to rule out that possibility himself. The estimated speed is all that would support meteors, and the absence of ankle trails and the general tenor of the description seems to rule out the objects' having been daylight meteors.
