UFO spotted at Clark AFB in 1957

Summary

In November 1957, an observer at Clark AFB in the Philippines reported a round object the size of a grapefruit with a flashing white light. Initially appearing stationary, it vanished quickly to the east while climbing. The witness, along with his 11-year-old son, noted the object turned dull red when the light was off. The sighting lasted two to three minutes. Although a weather balloon was considered a likely explanation, no confirmation was made. The report suggests it might have been a balloon, but other possibilities remain open.
