Chilean Army Antofagasta Triangle 2010

On November 14, 2010, a large black triangular craft was observed hovering at approximately 500 feet altitude over the facilities of the ALMA radio telescope complex in the Atacama Desert — one of the world's most significant astronomical installations — and over the adjacent Chilean Army garrison. ALMA Observatory technical staff observed the craft and photographed it. The Chilean Air Force was notified and its Committee for the Study of Anomalous Aerial Phenomena (CEFAA) — Chile's official government UAP investigation body — conducted a formal investigation. CEFAA, which operates with the endorsement of the Chilean Ministry of National Defence, concluded that the object could not be identified as any known aircraft type and that its performance characteristics were inconsistent with any military or civilian platform in Chilean inventory or known foreign inventory. The CEFAA report was formally published. Chile's CEFAA is one of the few government UAP investigation bodies that publishes case conclusions.
