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.

It is extremely unlikely that these objects were meteors, although their speed would argue for such interpretation. And they been, however, one would expect much more brilliant light, a trail, and perhaps even detonation. Furthermore, their light in formation argues against their being meteoric.

The meager description suggests a light phenomenon rather than material objects. Has any auroral activity reported in the region at the time? The description answers were closely to a detached auroral streamer than to anything else, but this explanation is perhaps also far retracted.
