🇺🇸 USAF — Project Blue Book
In September 1955, a witness in Sacramento, California, spotted a silver object flying away rapidly. The object, approximately the size of a pen, was seen for a few seconds and was moving at a speed much greater than a conventional jet. Due to the brevity of the sighting and the delay in receiving the initial report, no follow-up investigation was authorized. The nature of the object remains unresolved.
The report classifies the sighting as a ground visual observation and suggests it could be a balloon, an aircraft, or an astronomical phenomenon. However, none of these explanations were confirmed. The object followed a direct path away from the observer, adding to the mystery of this case. Despite being an official report, no definitive conclusions were reached.
