On November 11, 2014, two Chilean Navy officers in an Airbus Cougar AS-532 helicopter filmed an unidentified object for nine minutes using a Wescam MX-15 HD infrared camera west of Santiago. The object was invisible to the naked eye and emitted two separate thermal plumes. Neither on-board radar nor two ground radar stations detected it. CEFAA's two-year investigation concluded unanimously: cause unknown.

CEFAA Director Gen. Ricardo Bermúdez stated: 'We do not know what it was, but we do know what it was not.' The committee ruled out military and civilian aircraft, weather balloons, drones, and atmospheric phenomena. Nuclear chemist Mario Avila and aeronautical engineers participated in the analysis. The footage was declassified and released publicly in January 2017, making it one of the most scrutinized military UAP videos in South American history.
