Trans-en-Provence Case — UFO Landing Leaves Traces Confirmed by French Government Lab

On January 8, 1981, a retired contractor named Renato Nicolaï was working in his garden near Trans-en-Provence, France when he heard a whistling sound and saw a saucer-shaped object about the size of a car descend into his lower field, rest for a few seconds, then take off rapidly. At the landing site, Nicolaï found two concentric circles of marks in the ground, blackened soil, and what appeared to be scraping marks. The local gendarmerie photographed the traces and took soil and plant samples. The case was referred to GEPAN, the official French government UFO investigation unit. GEPAN's analysis — conducted by a team of scientists — found that the soil at the landing site had been exposed to temperatures between 300 and 600 degrees Celsius. The soil's biochemical and physicochemical properties had been altered in ways consistent with a strong electromagnetic field. Alfalfa plants at the site showed degraded chlorophyll at a rate consistent with controlled exposure tests. The Trans-en-Provence case is considered by many researchers to be the best physically documented ground trace UAP case ever investigated. GEPAN issued a formal report confirming the trace evidence was real and unexplained. It remains a cornerstone of French government involvement in UAP research.
