Discoid UAP over San Diego 1955

Summary

In August 1955, a witness in San Diego observed a silver, disc-shaped object moving from west to east. The sighting lasted 39 seconds and the object made a jet-like noise. Although the report suggested it might be an aircraft, no photographs or radar were used to confirm the object's identity. The detailed description of level flight and distinctive sound caused some confusion about its nature.

The report, part of Project 10073, did not reach a definitive conclusion, as options such as balloon, aircraft, or astronomical phenomenon were considered but not confirmed. The repeated mention of the British American Tobacco Co. in the document suggests a processing error or incorrect use of the form. This case reflects the ambiguity surrounding many UAP reports from that era.
