UFO Sighting Report — Duluth, Minnesota, 9 April 1965

On April 9, 1965, at 1658Z, two pilots from the 179th Air National Guard Fighter Interceptor Squadron, Major Albert Amatuzio and 2nd Lieutenant Raymond Klosowski, observed an unidentified object while flying F-89 aircraft. The object was described as a round, white, basketball-sized entity located at an altitude between 40,000 and 44,000 feet. The pilots reported that the object was stationary on a track of 140 degrees and exhibited no maneuvers. The pilots attempted to climb to the object's altitude but were unable to reach it. The observation lasted for approximately 30 minutes before the object faded from view. The incident was reported by the 756th Radar Squadron to various Air Force commands, including the 30th Air Division (SAGE) and the Duluth Air Defense Sector. Official analysis concluded that the object was a balloon, noting that weather stations in St. Cloud and Minneapolis had both released balloons during the relevant time period. The report explicitly states that no data presented conflicted with the balloon explanation, and the preparing officer noted that the pilots themselves described the object as looking similar to a balloon.
