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.

Considering this incident with 138, 53, and 40, one is forced to conclude that the object observed from London's array Air Base on the evening of 7 January 1963 was the planet Venus.

One report of the incident gives the location of the object as 600-1200°, or approximately opposite from that stated by other observers and that of Yemua. Conclusively, since the two of observation was the same, this means that one witness either was looking at a different object or had his directions mixed. Also the description otherwise agrees generally with the rest, and almost it is assumed throughout the reports that all observers were visible; the same object, the latter interpretation seems probable.

altmansta state the object "couldn't have been a star" (of course, it wasn't), because the sky was completely overcast. However, reports from the Columbus weather bureau indicate that, although the afternoon was cloudy, the sky was clear by 1930 hours. (This does not mean, of course, that there were up clouds near the western carlson.)

For possible explanations of the "tauties" reported by observers of this object, and further discussion of the incidents, see report on 233.
