GEIPAN, operated by the French space agency CNES, collects, investigates and archives public and official UAP reports. The document details its multi-step process involving witness interviews, field investigations, meteorological and astronomical cross-checks, and expert analysis. Statistics show the large majority of cases (over 60%) are identified as misperceptions of aircraft, balloons, drones, planets or meteors. Approximately 3–4% remain unexplained (Category D) after thorough study, with no evidence of extraterrestrial activity or defence threats identified. The programme emphasizes public transparency by publishing anonymized case files online to support potential future scientific research.
