Spherical UFO sighted over Loma Linda in 1957

Summary

In December 1957, a witness in Loma Linda, California, reported seeing two spherical objects the size of a basketball. They had a bluish-white color and left a trail. Small white dots appeared at the end of the objects. The sighting lasted 2 to 3 minutes, and the objects slowly moved toward Norton Air Force Base before disappearing north of San Bernardino. Although a weather balloon was considered, the data was inconclusive.

The observation was recorded as a ground visual, with no radar or photographs. The source was a civilian, whose name was redacted. The responsible officer concluded it could be an aircraft, but a balloon was not ruled out. The detailed description and unusual trajectory generated some uncertainty in the official evaluation.
