Correspondence regarding biochemical analysis of soil and plant samples from Trans-en-Provence landing site

This collection of correspondence documents the biochemical analysis of plant samples collected from a landing site in Trans-en-Provence, France, following an incident on January 9, 1981. The analysis was conducted by a scientist at the INRA (National Institute of Agricultural Research) laboratory in Avignon, in collaboration with G.E.P.A.N. (the French government's UFO study group) and the local Gendarmerie. The correspondence tracks the receipt of plant samples—specifically 'Trèfle rampant' (creeping clover)—from the center of the landing trace and from control locations at varying distances. The scientist reports significant and unexpected biochemical findings in the samples taken from the center of the trace. These findings include a quantitative alteration of the pigment equipment, specifically a decrease in chlorophylls and an increase in their metallic-core-deprived derivatives. Furthermore, the analysis identified several completely new compounds in the center sample that were strictly absent in all control samples. The author expresses significant caution and surprise, noting that these biochemical 'monstrosities' do not match the effects observed in plants exposed to radiation, nor do they resemble any known mutant profiles. The scientist requests further collaboration, including the use of radiation detection equipment and the collection of seeds from the affected plants to monitor for long-term effects. The documents reflect a formal, scientific approach to investigating the physical traces left by an Unidentified Aerial Phenomenon, emphasizing the need for rigorous control samples and detailed comparative analysis.
