Red lights on a road in Essonne at night in 1981

Summary

In the early hours of an October 1981 night, a couple in Essonne saw red lights that appeared to approach them. Startled by the flashes, they left the area without hearing any noise. The gendarmerie was notified days later but found no traces. Only one testimony was recorded, preventing a deeper investigation. Initially classified as D, the case was later reclassified as C due to insufficient information. Hypotheses such as farm vehicles or motorcycles were considered but deemed implausible given the hour and circumstances. The lack of additional witnesses and physical evidence left the case unexplained.
