Project 10073 Record Card — Presque Isle, Me., 8 October 1957

On October 8, 1957, at 1255Z, a civilian witness in Presque Isle, Maine, reported observing a silver object in the sky. The witness, described as a housewife, reported that the object appeared to be an aircraft with wings and was flying in a straight line at an altitude of 45 to 60 degrees above the horizon. The observation lasted for approximately two to three minutes. The witness noted that there were two aircraft in the area at the time of the sighting. Official military documentation, including a Project 10073 record card and a teletype message from the 75th Fighter Interceptor Squadron, indicates that the object was likely an aircraft. The weather conditions at the time were reported as clear with some cirrus clouds and high thin overcast. The evaluation of the source and the content of the report was classified as C-3. The report notes that a weather balloon was released from the US Weather Station at Caribou, Maine, at 1140Z, which burst at 1306Z, though the sighting report itself concludes the object was likely an aircraft.
