Luminous spheres at Le Mas-d'Agenais traced to a spotlight

Summary

On the night of 21 July 1993 six people watched luminous spheres spinning across the sky and sweeping the horizon at Le Mas-d'Agenais. GEIPAN's investigation traced the source to a spotlight being tested in the car park of a nearby dance hall. The device emitted thirty rotating beams that swept the horizon, creating the illusion of flying objects. Classification: A — explained.
