🇺🇸 USAF — Project Blue Book
In 1961, an official in Fremont, California, reported a unidentified flying object with red and green lights. The object, described as grapefruit-sized and colored pink, white, and solid bronze, was making circular turns. There were radio interferences and it was observed for a considerable time. Although initially thought to be a balloon, investigators concluded it was likely an aircraft due to the description of the lights and flight pattern.
