Return to Trans-en-Provence

Abstract—The site of the 1981 Trans-en-Provence UFO case was visited again during 1988. Soil samples taken at the time of the initial investigation were analyzed in an American laboratory in an effort to valídate the Centre National d’Etudes Spatiales (CNES) study of the case. The results of the interviews with the witness and his wife, and the examination of samples taken at the surface and below the surface of the physical trace support the findings of the CNES team and the truthfulness of the witness’ testimony. In particular, it was found that the surface sample only diífered from the depth sample by the presence of biological (plant and insect) material on the surface. Calcium and silicon were the dominant elements in all fields exam-ined, with aluminum and iron also present. No indication was found of cement powder, oil, or chemical contaminants that could have indicated the presence of tractors or other industrial vehicles at the site.
