The Trans-en-Provence Case was an event 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 Frenchdepartement of Var. It was described in Popular Mechanics as "perhaps the most completely and carefully documented sighting of all time".
Event details
The case began on January 8, 1981 at 5pm. Renato Nicolaï, a 55-year-old farmer, heard a strange whistling sound while performing agricultural work on his property. He then saw a saucer-shaped object about eight feet in diameter land about away at a lower elevation. According to the witness, "The device had the shape of two saucers, one inverted on top of the other. It must have measured about 1.5 meters in height. It was the color oflead. This device had a ridge all the way around its circumference. Under the machine I saw two kinds of pieces as it was lifting off. They could be reactors or feet. There were also two other circles which looked like trapdoors. The two reactors, or feet, extended about below the body of the machine." Nicolaï claimed the object took off almost immediately, rising above the treeline and departing to the north east. It left burn markson the ground where it had supposedly sat. The localgendarmerie were notified of the event the following day by Nicolaï directly on the advice of his neighbor's wife, Mrs. Morin. The gendarmerie proceeded to interview Nicolaï, take photos of the scene, and collect soil and plant samples from the field. The case was later sent to GEIPAN—or GEPAN as it was known at that time—for review.
Analysis of evidence
GEPAN analysis noted that the ground had been compressed by a mechanical pressure of about 4 or 5 tons, and heated to between. Trace amounts of phosphate and zinc were found in the sample material, and analysis of resident alfalfa near the landing site showed chlorophyll levels between 30% and 50% lower than expected.
Impressions and explanations
Nicolaï had initially believed the object to be an experimental military device. The close proximity of the site to the Canjuersmilitary base makes such a theory generally plausible. However, GEPAN's investigation focused on conventional explanations, such as atmospheric or terrain causes of a terrestrial nature. But despite a joint investigation by GEPAN and the gendarmerie which lasted for two years no plausible explanation was found.
Analysis
Some French scientists insist that the GEPAN investigation was flawed, especially the study of the physical trace. The police report said that the trace, which appeared on an active road, looked like one made by the tire of a car. This explanation was dismissed by GEPAN because of the sole witness saying otherwise. The physical trace shown on the picture is not a perfect circle, in fact there are two more-or-less semicircles crossing over each other. Also, a circular shape does not coincide with the description of the UFO made by Nikolaï. In an interview for French television, Nikolaï confirmed that there were vehicles passing by on the road at the time of the sighting.
