Disco laser mistaken for UFO at Saint-Branchs

Summary

In May 1993 three car occupants near Saint-Branchs watched an elongated bluish light repeatedly sweep in front of their vehicle at headlight height for several kilometres. GEIPAN re-examined the case in 2018 and concluded the phenomenon was almost certainly a nightclub laser reflected off the cloud layer. The description matched other known laser cases in its database, and a similar sighting in the same area in December 1993 was traced to a device called 'Sky Rose' producing identical visual effects. Although the specific equipment was never located, the case was reclassified as A — explained with high probability.
