Pulp Magazine Cover, July 1948

This catalog entry documents UFO sighting reports compiled under Project Sign/Grudge, the U.S. Air Force's official UFO investigation program. The primary content consists of a July 4, 1948 incident report from Dravosburg, Pennsylvania, in which a witness and his wife observed a light resembling a star moving erratically across the night sky at 11:15 P.M. EST. The object stopped multiple times (for 5 seconds, then at least 15 seconds), changed direction, and eventually disappeared. The witness ruled out conventional aircraft due to the absence of noise and the object's movement capabilities. Military correspondence forwards the civilian report through official channels. The document concludes with Dr. Hynek's evaluation index categorizing 240+ incidents by explanation type: astronomical phenomena, balloons/aircraft, rockets/flares, miscellaneous explanations, and unexplained sightings lacking sufficient evidence for determination.
