UFO sighted in Chicago in 1966

Summary

In September 1966, a civilian in Chicago reported seeing an unidentified object that remained visible for about an hour. The witness described the object as round and slightly flat, with a diameter of approximately 13 feet. The object was moving in a south-southwest direction, circling the sky. Despite the duration of the sighting, no photographs or physical evidence were obtained, which hindered evaluation by the Air Force's Project Blue Book. The report concluded that the data were insufficient for a conclusive evaluation.

The witness used binoculars to observe the phenomenon, suggesting a serious approach to the sighting. However, the lack of additional information, such as weather conditions or possible conventional explanations, left the investigation without concrete answers. Although the object could not be identified, the testimony was recorded as part of the effort to understand UFO reports at the time.
