GEIPAN Classification System and Statistics Overview

GEIPAN, a unit of the French space agency CNES, collects, analyses, and archives public and official reports of unidentified aerospace phenomena using a multidisciplinary scientific approach involving experts in physics, meteorology, aviation, and human factors. Cases are classified as A (identified), B (probably identified), C (insufficient data), or D (unidentified after investigation). Over approximately 40 years and thousands of testimonies, statistics indicate roughly 63% explained as misidentifications or perception errors, 33% unassessable due to lack of data, and about 3.4% unexplained (dropping to around 2% in recent years with improved tools and re-evaluations). The program emphasises that it does not research extraterrestrial life or paranormal phenomena and publishes anonymised case files and conclusions for public and scientific scrutiny, with periodic re-evaluation of D cases. No evidence of extraordinary aerial vehicles is presented; the focus remains on rational explanations where data permits.
