GEIPAN

France is widely considered a pioneer in government transparency regarding UAPs. The government established GEIPAN (Group for the Study and Information of Unidentified Aerospace Phenomena), which operates directly under CNES (the French Space Agency). They rigorously investigate reports and maintain a massive, publicly accessible database of their findings, categorizing sightings from explained to completely unexplainable. The link points to the documentation section of the Geipan website which includes cases, briefs, methodology documents and conference proceedings.
