This is a list of alleged sightings of unidentified flying objects or UFOs in France.
October 17, 1952, Oloron-Sainte-Marie. Many people saw a cigar-shaped UFO accompanied by 30 disc-shaped objects. These smaller UFOs dropped a white siliceous cotton which covered tree branches and roofs.[3][4] Some French skeptics thought that the UFOs were an optical phenomenon caused by the refraction of the sun's rays and the siliceous cotton was caused by a migration of field spiders.[5]
