PROJECT 10073 RECORD CARD — 11 July 1956, Wilmington, Delaware

On July 11, 1956, at approximately 0200Z, a civilian observer in Wilmington, Delaware, reported a sighting of an unidentified aerial object. The witness described the object as round, flat, and pink in color, with a fluorescent appearance. The observer estimated the size of the object to be equivalent to a quarter held at arm's length. The object maintained a steady, level flight path, traveling from south to north in a straight line. The duration of the observation was reported as being between one and three minutes. The sighting was conducted by ground observation with the naked eye. Official documentation of the event includes a Project 10073 record card and a teletype report transmitted from the Flight Service Center at Olmsted Air Force Base, Pennsylvania, to the Commander of the Air Defense Command at Ent Air Force Base, Colorado, and the Air Technical Intelligence Center at Wright-Patterson Air Force Base. The report notes that there were no photographs taken and no radar contact associated with the event. Weather conditions at the time were recorded as having scattered clouds. Captain William E. Anderson of the USAF signed the report. The final evaluation provided in the record card suggests that the characteristics of the object—specifically its steady, level, and straight flight path—indicate the possibility that the sighting was generated by an aircraft.
