The Chilean Navy UFO Video

The Sighting

On November 11, 2014, the crew of a Chilean Navy AS532 Cougar helicopter, conducting a routine daytime coastal patrol along Chile's central coast between San Antonio and Quintero, recorded roughly nine to ten minutes of infrared and visible-light video showing an unusual aerial object roughly 35 to 40 miles away. In the infrared footage, the object appeared as two blurry, roundish thermal blobs connected together, moving slowly westward and invisible to the naked eye at that distance; the helicopter's own radar did not detect it. Most strikingly, the object appeared to release a thick, motionless black trail that hung in the sky rather than dispersing as ordinary exhaust would.

The Investigation

The footage was submitted to CEFAA, the Chilean government's own Committee for the Study of Anomalous Aerial Phenomena — a rare instance of an air force formally tasking scientists with evaluating a UAP report. Over two years of investigation, CEFAA's own scientific panel could not identify a conventional cause matching the object's apparent low altitude and behavior, concluding it was most likely a medium-haul twin-jet airliner in a landing phase, and publicly released the video in early January 2017 as an officially unresolved case, drawing international headlines describing the Chilean Navy as unable to explain the footage. A separately commissioned French analysis by the IPACO group speculated the black trail might represent aircraft cabin wastewater discharge rather than a contrail.

The Explanations

Within days of the footage's public release, independent researchers on the Metabunk analysis forum, led by Mick West alongside contributors using the handles Trailblazer and Trailspotter, cross-referenced archived commercial flight-tracking data (Planefinder ADS-B records and FlightAware GPS logs) against the helicopter's documented position and camera bearing. Their reconstruction identified the object as Iberia Airlines flight IB6830, an Airbus A340 four-engine aircraft that had departed Santiago and was climbing through approximately 26,755 to 28,963 feet at the time of the sighting — a distance, heading, banking maneuver, and thermal signature (the four engines forming a distinctive 'peanut'-shaped infrared blob) that matched the video frame by frame. The black trail, they determined, was not engine exhaust (which requires far higher altitudes to condense visibly) but a semi-persistent aerodynamic contrail, formed between roughly 20,000 and 28,000 feet by pressure changes over the airframe during a climbing turn, appearing dark against the infrared-cold sky because it registered as comparatively warm condensed water vapor. The analysis further suggested a second aircraft, the earlier-favored candidate LATAM flight LA330, may also appear later in the footage, meaning CEFAA's own two-year investigation had overlooked that as many as two separate, entirely ordinary airliners were visible in different portions of the same video — a conclusion reached only because independent analysts checked actual flight data that the official inquiry never had.

CEFAA's defenders note the committee explicitly avoided claiming extraterrestrial origin and always described the case using the more cautious term 'unidentified,' while its critics argue the episode is a clean demonstration of how even a well-funded government investigation can miss a mundane explanation that crowdsourced technical analysts, given the right public data, resolved within five days.

Why It Endures

The Chilean Navy video is now the textbook case for how thermal-video UAP sightings get resolved in the smartphone-and-open-data era: not by an official agency's two-year deliberation, but by strangers on an internet forum cross-referencing free flight-tracker archives against a helicopter's GPS log. It remains one of the clearest post-mortems available anywhere of exactly how, and how quickly, a 'the government can't explain this' headline can collapse once someone actually checks who else was flying that day.

The episode has become a reference point well beyond Chile, cited repeatedly in later debates over U.S. Navy UAP videos precisely because it demonstrates a general principle: infrared sensors compress a great deal of genuinely useful distance and motion information into a format that is very easy to misread without cross-referencing independent data, and a government agency's failure to identify a mundane cause is not, by itself, evidence of anything exotic — only evidence that nobody checked the one dataset that would have settled it. CEFAA never retracted its original 'unidentified' classification of the raw footage, but the broader UAP research community has largely treated the Metabunk analysis as the effective final word on what the Chilean Navy actually filmed that November afternoon.
