Ussy-sur-Marne: a triangle over a gendarmerie car
At 2:47 a.m. on 24 June 1994 three gendarmes near the A4 bridge at Ussy-sur-Marne, east of Paris, saw three yellow-white lights in a triangle with a triangular underside. It came toward them, hovered over their car and followed it, while their radios went dead; then it left westward and was a faint point on the horizon within a second. Their report, which cites a 1992 gendarmerie directive on studying UFOs, went to the Préfet and the air region's general. GEIPAN classed it unexplained.
