🇺🇸 USAF — Project Blue Book
In September 1951, F-86 pilots reported an unidentified object over Long Beach, California. The object, described as round or silver, was initially classified as a balloon. The aircraft attempted to intercept it but couldn't approach due to altitude and fuel limitations. A radiosonde balloon launched from Long Beach Airport matched the object's location and trajectory, suggesting it was a weather balloon. Although the pilots thought it could be an experimental aircraft, the investigation concluded it was likely a balloon. The confusion was due to the relative motion between the balloon and the aircraft.
