Dark hexagon with flashing lights over Amiens

Summary

At around seven in the morning on 15 February 1982, several witnesses in Amiens observed a dark hexagonal mass whose edges emitted intermittent white lights. The object moved without making any noise. No further details were collected, and GEIPAN classified the case as C, having found no conventional explanation. The unusual geometry and silence make this a distinctive entry in the records of unidentified aerial phenomena.
