Unidentified Flying Objects: Project "Grudge" (Technical Report No. 102-AC 49/15-100)

US Air Force, Air Materiel Command · 1949-08 · 413 pages · text by OCR

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.

with the exception of the order ("like polished nickel") and the lack of statement concerning a trail, the object reported in this incident might very well have been a daylight meteor. Bright meteors have been observed to move in many paths. The number of disappearance "malted into thin air" further supports this view. Time in sight and speed also elude. In short, it is more likely that this object was a bright meteor than that it was anything else.
