Trans-en-Provence Case

The Trans-en-Provence Case is one of the rare cases where an unidentified flying object is claimed to have left physical evidence, in the form of burnt residue on a field. The event took place on January 8, 1981, outside the town of Trans-en-Provence in the French departement of Var. It was described in Popular Mechanics as "perhaps the most completely and carefully documented sighting of all time".
