Round UFO sighted in Washington in 1956

Summary

In May 1956, a witness in Retail, Washington, observed a round object several feet in diameter, white in color, moving north. The sighting lasted only 4 seconds before the object disappeared. Although a balloon or meteor were considered, there was not enough data for a definitive evaluation. The report concluded it could be an astronomical phenomenon or an unknown object.

The report, part of Project 10073, did not include photographs or radar intercepts. The witness was a civilian and no other significant details were recorded. Despite the brief nature of the sighting, the object was described clearly, generating some interest among researchers at the time.
