🇺🇸 USAF — Project Blue Book
In September 1955, a witness in Oakland, California, observed an object resembling a ball with a dark tail that eventually exploded. The object was seen for 60 seconds, and although a meteor was initially considered, the data did not allow for a clear evaluation. The witness described the tail catching fire before the explosion, creating some confusion about its nature.
Military officials could not confirm the object's identity, and three F-86D aircraft were vectored to the sighting area but found nothing. The official report classified it as an aircraft, but no further details were provided. This case remains one of many where the lack of clear evidence keeps the mystery of the observed object unresolved.
