GEIPAN Documentation - Note Technique n° 1 to 17 and Related Scientific Studies

The technical notes provide frameworks for investigators, including identification aids, psychological and perceptual factors, and case categorization (A: identified; B: probable; C: insufficient data; D: unexplained). Scientific studies examine patterns in reports, historical waves, and specific phenomena like satellite flares. GEIPAN's process involves collecting witness reports via standardized questionnaires, cross-referencing with known phenomena (aircraft, balloons, astronomical events, drones), and archiving anonymized cases publicly. The body of work emphasizes scientific rigor, cooperation with experts from CNRS, Météo France, and the military, and public transparency. No evidence of extraordinary or extraterrestrial technology is found; unexplained cases are attributed to lack of data rather than anomalous craft. These documents form part of an ongoing operational archive rather than a single closed report.
