Project 10073 Record Card — Neptune, New Jersey, 21 October 1957

On 21 October 1957, a civilian observer in Neptune, New Jersey, reported a sighting of an unidentified object while visually tracking the Soviet Sputnik I satellite and its rocket booster. The observer, using 8x35mm binoculars, described the object as an identical, blinking, fast-moving counterpart to Sputnik I. According to the observer's account, the object appeared to be on a collision course with the satellite. Shortly thereafter, the observer noted two high-flying jet aircraft appearing from the southwest, which were described as soundless. The observer noted that the jets bore greenish-blue lights and were visible until they reached the eastern horizon. The observer provided a detailed sketch of the sky, mapping the paths of the satellite, the rocket, and the unidentified object relative to constellations such as Pegasus, Cassiopeia, and Serpens. The Air Intelligence Information Report, filed by the Intelligence Division of the First Air Force, notes that the report was forwarded through Fort Monmouth and the First Army. The official conclusion reached by the intelligence officers was that the object was likely a high-flying jet aircraft, though the report notes that further checks were being made at the time of the assessment. The report explicitly states that there was no physical evidence and that the analysis was negative.
