🇺🇸 USAF — Project Blue Book
In 1960, a witness in North Dakota reported seeing a blue object with a trailing flame, described as resembling a Roman candle. The sighting lasted about a minute and was classified as likely an aircraft. Although other possibilities like balloons or astronomical phenomena were considered, the most plausible explanation pointed to a jet aircraft. The observer's description, along with weather and wind data, helped rule out other options.
The official investigation concluded the object was probably an aircraft, though not definitively identified. The report highlights the speed and duration of the sighting, consistent with a jet. Despite the witness being unable to determine the exact size or shape, visual and meteorological details were key to the evaluation.
