About this archive

Indexed here are the documents published by bodies with an official mandate over unidentified anomalous phenomena — air forces, civil aviation authorities, national archives and defence ministries — together with the declassified files those states have released. An entry in this archive does not replace the original document: any rigorous use should go to the linked source.
