Sightings of a silver circular object in Danville in 1952

Summary

A 15-year-old in Danville, California, reported a silver, circular object in September 1952. He observed it for 30 seconds and described straight, level movements. Although the report suggests it might be a balloon, there's no clear evidence. The witness wasn't wearing glasses or optical instruments, and the object disappeared suddenly to the south. The lack of noise and unusual speed raised doubts about its conventional identity.

The official evaluation labeled it as "possibly a balloon," but no nearby launches were recorded. The report includes sketches by the witness showing the object's path. Despite questions about weather conditions and visibility, the mystery remains unresolved. The testimony, though brief, reflects the typical confusion of sightings from that era.
