🇺🇸 USAF — Project Blue Book
A 1957 report describes a luminous object seen for 1½ hours in San Diego, California. The witness described it as round, pencil-sized, with red, green, and white lights moving left to right and up and down. The observation was made from the ground and without photos. Investigators concluded the object was astronomical—specifically Aldebaran, a visible star in the night sky. The witness noted the object appeared on different days, suggesting repeated sightings, though it was never clearly identified.
The report includes weather and directional details but no conventional explanations like balloons or aircraft. Despite the long observation time, no additional data confirmed the nature of the phenomenon.
