Note Technique No 11 (Enquête 81/02)

This technical report (No. 11, Enquête 81/02) from the GEPAN (Groupe d'Études des Phénomènes Aérospatiaux Non Identifiés) details the investigation into a sighting reported by M. BLAISE on January 26, 1981. While driving his Citroën 2CV Dyane near the intersection of roads CDA and CDB in a mountainous region, the witness observed a cigar-shaped object, approximately 5 meters long and matte orange in color, with three white circular 'portholes.' The object approached his vehicle at a low altitude, causing the engine to stall. The witness exited the vehicle and observed the object move toward the East before disappearing over a ridge. The GEPAN investigation, conducted between January 29 and 30, 1981, included a reconstruction of the event, interviews with the witness and a local mechanic, and a technical examination of the vehicle. The vehicle's electrical system, specifically the alternator and diode bridge, was analyzed, but no definitive evidence of an interaction with an external agent was found. The report concludes that while the witness's account is consistent and the mechanical failure of the vehicle is documented, the phenomenon remains unidentified. The investigators also provide a psychological analysis of the witness, suggesting an obsessional personality type. The report includes technical annexes regarding the vehicle's electrical system and diode specifications.
