White circular UFO seen in Yuma in 1952

Summary

In April 1952, a group of weather observers in Yuma, Arizona reported a white, flat, circular object with an intermittent tail. They observed the phenomenon for about seven seconds, enough time to notice its irregular trajectory and high speed, which made it impossible to track with theodolites. The object made no sound and had a completely different appearance from any known balloon or phenomenon.

The observers, including engineers and officers with meteorological experience, all agreed they had never seen anything like it before. The official report did not conclude the object's nature but noted it did not match a balloon, aircraft, or astronomical phenomenon. The detailed description and the witnesses' reactions add a touch of mystery to this case, which remains unsolved.
