Summary

On April 5, 1980, at around 10:45 PM, a witness in Le Chesnay (France) observed a white glowing ball ascending in jerks, leaving a white trail behind. After reaching a certain height, the object moved horizontally at high speed before disappearing. Despite the investigation by the GEIPAN, the phenomenon could not be identified. The description of the object and its behavior did not match those of airplanes or any known natural phenomena. This case, classified as "D" by the GEIPAN, remains unexplained.
