Gyroscopic black UFO seen over a field in France

Summary

On March 31, 2013, a witness in France observed while driving an object that was black in color, rhombus-shaped with facets, and spinning on itself above a field. The sky was cloudy and there was no noticeable wind. Despite the witness's sincerity and a thorough field investigation, no additional testimonies or confirmations were obtained. The GEIPAN classified this case in category C due to the lack of reliable information. Although plausible hypotheses were proposed, they could not be confirmed or invalidated. The case is considered unusual but with a moderate to low level of mystery.
