Triangular lights over Saint-Haon-le-Châtel

Summary

In May 2004, two witnesses in Saint-Haon-le-Châtel reported a triangular object displaying red, green, and yellow lights and moving erratically, accompanied by an engine sound. Originally classified D (unexplained), the case was later reassessed. The witnesses had contacted a ufology association and the press but could not provide precise data such as angles or dimensions.

The review noted the proximity to Roanne airport and the object's heading toward other airfields. The lights matched aviation regulations for night flights. Discordant elements—a perceived blue light, irregular movements—were attributed to physiological effects or the witnesses' emotional state. GEIPAN reclassified the case as B, likely a small touring aircraft on a night VFR flight, though with reservations bordering on category C.
