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.

Incident g166 -- Los Angeles, California -- 3v au just 1966

The observer of these national states that the object looked like a rocket and was larger than a dart. We do not give the clear answer, but estimates the altitude as well over 10,000 feet. As this included glaciers, it appears to be currently the most reliance to a rocket must have been largely subjective.

although a rocket cannot be rolled out, it is also possible that the object seen was a bright power. If the hour of observation given is correct, it was late twilight. It seems that a bright meteor appearing at this time could give the general impression of a rocket lair; a trail.

The report states that the object was observed through field glasses taken from a Jerran Clan artillery piece and that each lens was 6" in diameter. This is an irregularly large also for a field glass. If the object occasionally filled the lens at that given altitude, it was of a truly tremendous size or the glass was out of issue. Furthermore, the telegram and summary state that the object was travelling from west to east ( another report says from north to south); if it had been a rocket heading east, the landing would probably have been reported.

All in all, the evidence supports the conclusion that the object was more likely a bright meteor than a huge rocket.
