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 43 -- جزء 6 that the object appeared essentially stationary (or moving steadily away from him) and that so could not seem to gain on it. In making up, this can be said: the evening sightings reported in Inalgese 200, 32, 33, and 48 were undoubtedly of the planet Venus. According to the daylight sightings from Godman Field and other places in Kentucky, there seems so far to be no single explanation that does not rely greatly on coincidence. If all reports were of a single object, in the knowledge of this investigator no man-made object would have been large enough and far enough away for the approximately simultaneous sightings. It is most unlikely, however, that so many separate persons should at that time care enough on Venus in the daylight sky. It seems, therefore, more probable that more than one object was involved; the sightings might have included two or more balloons (or aircraft); or they might have been both Venus (in the fatal ones) and balloons. For reasons given above, the latter explanation seems more likely. Based on a hypothesis does, however, still necessitate the inclusion of at least the objects other than Venus, and it certainly is coincidental that so many people would have answered this one day to be confused (to the extent of reporting the matter) by normal airborne objects. In no remain one possible, very plausible explanation for this fact, however, was the original report by any chance broadcast by local radio station? If so, with the general public on the alert, even UNCLASSIFIED
