Round UFO seen over Sacramento in 1966

Summary

In November 1966, a woman in North Sacramento, California, observed a dark, round object with three white lights. The object passed overhead and disappeared within thirty seconds, accompanied by a humming sound. Although initially considered unexplained, the investigation revealed it coincided with the arrival of a C-124 aircraft at McClellan Air Force Base. The observer, a 45-year-old divorced woman, was described as emotionally sensitive, leading investigators to conclude she had seen the aircraft landing. There was no physical evidence or additional reports to support an alternative explanation.
