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.
# CONSERVATIONS 1. That the investigation and study of reports of unidentified flying objects be reduced in scope. a. That current collection directives relative to unidentified flying objects be revised to provide for the submission of only those reports clearly indicating realistic technical applications. 2.
