Project 10073 Record — York, Pennsylvania, 12 June 1966

On June 12, 1966, the Sipe family of York, Pennsylvania, reported observing an unidentified aerial phenomenon for approximately 25 minutes. The witnesses, Richard Sipe, his wife Hazel, and their son Richard Jr., described the object as a flattened triangle that hovered over the treetops west of their home. They reported that the object moved in deliberate directions, including horizontal and vertical movements, and featured compartments that glowed with soft, multi-colored lights. The witnesses observed the object through binoculars and noted that it appeared larger than a star. The family reported the sighting to the local newspaper, 'The Gazette and Daily,' and subsequently to the Department of Defense. The Air Force, through Project Blue Book, investigated the report. Major Hector Quintanilla, Jr., Chief of Project Blue Book, initially requested further information via FTD Form 164. The official conclusion recorded on the Project 10073 record identified the object as the star Arcturus, noting its position at 290 degrees and 8 degrees elevation. The witnesses expressed concern regarding a dead or burned tree in the area, speculating about potential radioactivity, though they were hesitant to investigate it themselves.
