Round and silver UFO seen in Ventura, California

Summary

A round and shiny object was observed in Ventura, California, on May 21, 1957. A group of 22 people, including teachers and students, saw an object the size of a pinhead, silver or white in color, that appeared after the sonic boom of a jet. The object hardly moved and then began to oscillate until it disappeared from view. Despite the 23-minute observation, no radar detected it, and the area had a blind spot for detection.

Initial reports could not determine the object's nature with certainty. Balloons or small aircraft were considered, but no conclusive evidence was found. This sighting is part of a series of UFO reports from the time that highlight the confusion and lack of clear data. Although conventional explanations were ruled out, the case remains unsolved.
