UFO sighted near Oakland in 1952

Summary

In August 1952, a civilian in Oakland, California, reported seeing two balls of fire that traced a ten-mile circle before heading toward Hamilton AFB. The testimony didn't include details about speed, altitude, or sound, but it did mention that the event occurred in an area with 15-mile visibility. Although no photos were taken, weather and wind data at various altitudes were recorded. Military authorities responded with F-94 and F-89 aircraft, but failed to spot the phenomenon. The final evaluation considered it likely an aircraft, though other possibilities weren't ruled out.
