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.

Icadtech 306, a--; -- Jordan Field, Fort Wox, Louisiana -- ? January 1943 a discussion of all incidents reported for this date

Incidents 30, 32, 33, and 40 all occurred on 7 January 1940, with 33 involving the earth or planet Larsell. Installed attention has therefore been given to any possible astronomical body or phenomenon which might serve to identify the object or objects concerned. The four incidents are considered to other here.

Although the several reports differ considerably in regard to the bearing and motion of the object (usually for the motion that the afternoon and evening lights refer to the same phenomenon), they are generally consistent concerning the time, manner, and place of its dis-appearance over the horizon. Our and all truth are given as 1905 CST, about 260°, by supervors as rotten field; 1966 SCT, near southwest, by those at Lowbourn Air Base; and 1966-2000 SCT, about 810°, by those at Clinton County Air Base (there are, as is to be expected, slight differences in individual reports). Using this for the focal point of attack, one notes in偶然 that all these times and bodies A.A.TP closely with the time and place of the settling of Venus. Furthermore, all accounts except one agree that the object was low in the southwest before the time of disappearance. Reports vary in to details of its motion, but the overall notion was southwest and then over the horizon. These facts taken together preclude any question of coincidence. Furthermore, simultaneous observation from scattered locations proves that the object had negligible parallel, or, in short, that it was a very great distance away. All other statements concerning the object must,
