Chilean Air Force Colbún Encounter 2013

On November 11, 2013, a Chilean Navy Airbus Cougar helicopter crew conducting a routine coastal patrol filmed an unidentified object for nine minutes using an infrared FLIR camera. The object flew at approximately 1,500 feet and emitted two separate trails of a hot gas or liquid in brief puffs. The crew attempted to communicate with the object and alerted ground radar, but no contact was established. Chile's official government UAP investigation body, CEFAA (Comité de Estudios de Fenómenos Aéreos Anomalos), analyzed the footage for two years with experts including meteorologists, Air Force officers, oceanographers, and nuclear energy scientists. CEFAA concluded the object was genuine and unidentifiable, ruling out aircraft, balloons, drones, and birds. The footage was released publicly in January 2017 and was authenticated by multiple independent technical analysts. It became one of the most widely cited examples of official government release of UAP evidence, predating the US Navy video releases by two years.
