EDINTEN, NORTH CAROLINADecember 1954

On December 7, 1954, a pilot stationed near Edenton, North Carolina spotted a silver, semi-spherical object flying at extremely high speed. The object first appeared to be a parachute or weather balloon drifting slowly. Within seconds, it accelerated rapidly and climbed to a higher altitude, making identification difficult. The pilot made a hard right turn toward the object but could not close the distance due to the object's extreme acceleration.

The pilot was a highly experienced USMC naval aviator with eight years of service and approximately 2,200 hours of flight time. A passenger aboard the aircraft, identified as a corporal, also witnessed the event. Both observers were considered reliable. They ruled out conventional explanations like parachutes or weather balloons based on the object's sudden and sustained acceleration, which exceeded the capabilities of any equipment they were familiar with. The observers noted the object was considerably larger than a parachute or balloon and exhibited no features consistent with those objects.

The sighting lasted approximately 20 seconds from initial observation to the moment further identification became impossible. The object was heading south-southwest at an extremely high altitude when last observed. The file indicates the Air Force investigation was being conducted by Flight 3-H at McGuire Air Force Base.

The Air Force's initial evaluation, noted on the case cover sheet, was that the object was "probably a balloon." However, the detailed pilot report and the observers' explicit discounting of the balloon hypothesis based on the object's performance characteristics suggest significant discrepancies between the official conclusion and the evidence presented in the case file.
