Bourges 1980, silent sighting with no explanation

Summary

On October 26, 1980, a witness in Bourges observed a series of bright flashes in the sky that reminded him of an aircraft's rotating beacon. He then saw a very bright flame followed by a black smoke trail, all without any sound. Thinking it might be an aircraft emergency, he contacted the nearest control tower. However, during the gendarmerie investigation, no aircraft in distress or rocket launches were reported in the area. No other witnesses were found, and the case remains unexplained due to the lack of additional information.
