Trans-en-Provence 1981: An Unexplained Case with Confirmed Physical Traces and Rigorous Scientific Scrutiny

To the point

Renato Nicolai witnessed a dome-shaped craft land near Trans-en-Provence in 1981 and leave a roughly 2-meter circular ground trace, which GEPAN under Jean-Jacques Velasco investigated and found unusual soil elements, plant degradation, and heating up to about 600°C without burning, resulting in a Type D classification of an unexplained phenomenon with confirmed physical traces and an undetermined origin, a conclusion later supported by an independent 1988 review and the 2007 declassification of GEIPAN files, while ongoing debate among ufologists and skeptics highlights the case's impact on scientific scrutiny and transparency.
