🇺🇸 USAF — Project Blue Book
In November 1967, an observer in California spotted a large, round, white object as bright as a star. The object moved in an unusual way: it first rose and fell, swayed back and forth, and then rapidly accelerated eastward before disappearing. During its movement, it changed shape and demonstrated complex maneuvers. Although the observation lasted 10 minutes, key details such as the exact direction, altitude, or precise location of the witness are missing, making a deeper analysis difficult.
The official report does not include physical evidence or photographs of the event, and the testimony is limited to a visual description. The sighting was reported using an official Air Force form, but no additional data or follow-up was recorded. Like many cases from that era, this one remains unexplained, and its value lies in the description of an aerial phenomenon with characteristics that challenge known technological capabilities at the time.
