Analyse statistique

This methodological and statistical paper reviews the classification of aerospace phenomena reported to GEIPAN. It presents the breakdown of cases into categories: perfectly identified (A), probably identified (B), insufficient data (C), and those that remain unidentified after thorough investigation (D). The analysis shows that only a small percentage (around 3%) fall into the truly unexplained category after expert review, with the majority explained as aircraft, balloons, astronomical objects, or atmospheric phenomena. It supports GEIPAN's transparent public archive approach and underscores the value of rigorous, standardized investigation methods.
