On 8 January 1981 in Trans-en-Provence, France, farmer Renato Nicolaï reported a disc-shaped object landing briefly in his garden, leaving a circular ring on the ground. France's official UFO study body GEPAN/SEPRA collected soil and plant samples, and laboratory analysis (by Michel Bounias and others) reported biochemical and trace anomalies in the affected vegetation. It is frequently cited as the best-documented physical-trace case, though the interpretation of the lab findings is debated.
