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.
Involunt 33, a-; == 1% .9 too was the planet Venus. In the absence of exact measures, however, it is impossible to establish that it was or was not. (It is un- fortunate that theodolite measures of the artemicon observations were evidently not made.) It has been officially reported that the object has a Dary sphere ray balloon. If this can be established, it is to be preferred as an explanation. However, if can accept the assumption that reports from various other locations in the state refer to the same object, any such device must have been a good many miles. 26 to 20 in order to have been seen clearly, almost simultaneously. From places 17. miles apart. It is entirely possible, of course, that the first alightings were of some sort of balloon or aircraft, but that was their report came to Jordan Field, a careful marking of the sky revealed hence, and it could be that Lieutenant Lantell did actually give chase to the planet, even though whatever object had been the source of the exoite-ment elsewhere had disappeared. At the altitudes that the pilot roasted, Venus would have been very much more easily observed than from the ground, and it might even be that he did not actually pick it up until no was at a considerable altitude. The one piece of evidence that leads this investigator to believe that at the time of Lieutenant Lantell's death he was actually trying to reach Venus is
