Project 10073 Record Card — Irondequoit, New York, 25 July 1959

This document contains a Project 10073 record card and associated correspondence regarding an unidentified aerial phenomenon reported by a civilian in Irondequoit, New York, on July 25, 1959. The witness, a technical machine illustrator and private pilot, reported observing a brownish-black object shaped like a quarter-moon with a white bubble or turret-like protrusion in the center. The sighting occurred in broad daylight while the witness was in his yard using 6x30 binoculars. He described the object as having no visible engine or vapor trail, moving at tremendous speed, and performing a banking maneuver before disappearing behind trees. The witness estimated the object's size to be comparable to a DC-3 aircraft without a fuselage and its speed to be at least 800 mph. He noted that the object appeared to be a solid machine rather than a natural phenomenon. The witness expressed concern about being ridiculed for his report, noting that he had previously witnessed other unexplained aerial events, including F-86 jets chasing square-shaped objects. The Air Force, represented by Major Lawrence J. Tacker, acknowledged the report in a letter dated September 2, 1959, stating that the initial information provided was insufficient for a valid conclusion and requesting the completion of a formal Air Force questionnaire. The final project record card notes that no conclusion was reached regarding the cause of the sighting, and the case was officially classified as unidentified. The record card explicitly mentions that while the possibility of a meteor was considered, it did not account for the observed maneuvers and the level of detail reported by the witness during the short duration of the sighting.
