🇺🇸 USAF — Project Blue Book
In May 1961, multiple observers in Japan reported a luminous object with a tail, moving in a descending arc. It was a white, flaming object with a tail, observed for about 10 to 12 seconds. The witnesses included military and air traffic personnel at Atsugi base, adding credibility to the sighting. Although a meteor was considered, the data was inconclusive. The report was classified and sent to various air intelligence units for analysis.
