Rectangular UFO seen over Stockton in 1952

Summary

In May 1952, a group of observers in Stockton, California, reported a bright silver rectangular object that remained stationary in the sky for 25 minutes. The object was observed at an estimated altitude of 30,000 feet and was detected by radar, though no interception was successful. Witnesses, including an artillery officer and several civilians, agreed the object showed no characteristics of aircraft or celestial bodies. Some suggested it could be a weather balloon, though no scheduled launches were recorded in the area at that time. The official investigation classified it as an unexplained phenomenon.

The description of the object as rectangular and luminous, along with its immobility, generated curiosity and debate. Despite radar attempts and visual observation, the object simply vanished from the sky without a trace. The absence of clouds and presence of moderate wind added mystery to the case. Ultimately, investigators concluded there was insufficient evidence to determine its nature with certainty, closing the case without a definitive resolution.
