1955 UFO sighting in California

Summary

A fighter pilot observed a bright object falling vertically. It was seen 90 miles southeast of Sacramento, California. The object, resembling an aircraft at a distance, descended without visible details. It was considered possibly a weather balloon that burst and fell. There was no visible explosion or smoke trail. The only observer was the pilot, who reported a straight descent. Other explanations like aircraft or astronomical phenomena were dismissed. Insufficient precise data hindered a definitive evaluation.
