GEIPAN Statistics and Classification Summary

GEIPAN, part of the French space agency CNES, collects, investigates, and publicly archives witness reports of unidentified aerospace phenomena. The document presents aggregated data on thousands of cases. The majority are explained as conventional phenomena (aircraft, balloons, drones, astronomical objects, atmospheric effects, or optical artifacts). Approximately 28% are perfectly identified (Category A), 39% probably identified (Category B), 30% lack sufficient data for identification (Category C), and roughly 3% remain unexplained even after detailed investigation (Category D). The report emphasizes scientific methodology, use of multiple data sources including photos, videos, radar, and ground traces when available, and stresses that no evidence of extraterrestrial origin has been found in any case. Unexplained cases are retained for possible future scientific re-examination. The process involves volunteer investigators, institutional experts, and a steering committee. All finalized case files are published on the official website with witness anonymity preserved.
