The Chilean Navy / CEFAA IR Case disputed-optical-artifact
On 11 November 2014 a Chilean Navy helicopter crew recorded ~9 minutes of
infrared (FLIR) video of an unidentified object off the central coast that
twice appeared to eject a hot plume and did not show on radar; Chile's official
UFO agency CEFAA investigated for ~2 years and released it in 2017 as
unexplained — but analysts then argued it was a distant airliner whose contrail
and engine glow mimicked the anomalous features.
This is a modern, official, government-investigated, instrumented (military IR)
case from a national UFO agency outside the US — the corpus's strongest South
American sensor case, alongside the US Navy FLIR videos, Aguadilla, and the
2004 Mexican Air Force case. It is doubly valuable because it became a clean
skeptical test case: the same official footage CEFAA called unexplained was,
within days of release, argued to be a mundane distant aircraft. A model study
in instrumented-but-ambiguous IR footage versus a prosaic explanation.
Timeline
2014-11-11
A Chilean Navy Airbus Cougar AS532 on coastal patrol, carrying a pilot and a
technician testing a WESCAM MX-15 HD FLIR camera, records ~9-10 minutes of
IR video of an object first seen with the naked eye at an estimated 35-40
miles, near the helicopter's ~4,500 ft altitude. The pilot describes a flat,
elongated structure with two thermal spotlights; the object twice trails a
hot plume and does not appear on radar.

2014-2016
CEFAA (Comite de Estudios de Fenomenos Aereos Anomalos), under Chile's civil
aviation directorate, investigates for ~2 years with meteorologists, a nuclear
chemist, an astrophysicist, image experts, and Air Force analysts.

CEFAA releases the footage publicly; Bermudez says the panel could only
determine what it was NOT, classifying it a UAP. Leslie Kean reports it.

2017-after
Analysts led by Mick West (Metabunk), with Scott Brando and French
IPACO-linked groups, argue the object is a distant climbing commercial
airliner (candidate flights Iberia IB6830 — an A340 — or LATAM LA330): engine
thermal bloom as the two hotspots, a transient aerodynamic contrail as the
'plume,' parallax as the apparent slowness — matching independent ADS-B data.

- The Navy helicopter crew — An experienced Navy captain (pilot) and a FLIR technician — the primary witnesses and camera operators rank at time: primary witness to: the IR object and its plume
- Mick West — Analyst who led the crowdsourced aircraft-contrail analysis identifying candidate flights and the engine-bloom/contrail mechanism rank at time: role: the leading prosaic analysis
- Scott Brando — Researcher (ufoofinterest) who curated and amplified the aircraft explanation rank at time: role: the debunk synthesis
Object — reported
shape
in infrared, a white, semi-oval/elongated 'peanut'-shaped hot blob with two bright thermal hotspots; twice trailing a high-thermal plume
size
indeterminate — apparent size depends on a contested distance (CEFAA ~35-40 mi near helicopter altitude; skeptics ~65 mi and ~20,000+ ft)
surface features
two thermal hotspots (read by skeptics as twin/quad engine thermal bloom); a transient plume rendered dark by IR auto-leveling against the cold sky
observed behaviors
- flying roughly level and slow relative to the background over ~9 minutes, twice ejecting a hot plume, and not appearing on radar
- on the prosaic reading: a distant climbing airliner whose engine bloom gives the two hotspots, a brief aerodynamic contrail gives the 'plume,' and distance/parallax gives the apparent slowness
- radar missing a high object beyond helicopter range — consistent with the aircraft reading
Theories that invoke this case (3)
The face-value reading: official military IR footage of a structured object with anomalous plume behavior, not on radar — taken as a genuine UAP if credited.
The instrumented-evidence reading: a real, official IR recording analyzed frame-by-frame as a physical data set — here yielding a distant-aircraft solution rather than an anomaly.
The perceptual reading the prosaic case turns on: distance/parallax misjudgment and IR auto-leveling making an ordinary airliner read as a slow, plume-ejecting unknown.
Theories that do NOT invoke this case — and why
an aerial IR case, not a creature record
the stimulus is a structured aircraft, not an atmospheric luminous phenomenon
an official investigation of one case, not an arc of managed disclosure
Conventional explanations advanced — and their status
A distant commercial airliner + aerodynamic contrail
proponents: Mick West / Metabunk · Scott Brando · French IPACO-linked analysts
The leading, specific, falsifiable explanation: candidate flights IB6830/LA330 match the bearing on ADS-B data; the two hotspots are engine thermal bloom, the 'plume' a transient aerodynamic contrail rendered dark by IR auto-leveling, the slowness parallax, and the radar-absence a high object beyond helicopter range.
A genuinely unexplained UAP
proponents: CEFAA
The official conclusion, but it rested on a near-helicopter distance/altitude assumption that the later flight-data reconstruction directly contradicts; it predates and does not rebut the aircraft analysis.
Where further investigation has leverage
- ADS-B / flight-track data (already extracted) for the exact UTC window, fixing candidate flight positions and altitudes against the camera bearing.
- MX-15 camera metadata (bearing, zoom, field of view per timestamp) to bound the line-of-sight and angular size, and resolve the distance dispute.
- Aerodynamic-contrail physics for a climbing airliner, and an account of why a high, distant aircraft went unseen by helicopter and ground radar.
Corpus status
disputed-optical-artifact
A high-provenance official IR case with a robust prosaic explanation: the
footage is genuine and seriously investigated, but the anomalous features
(slowness, plume, two hotspots, radar-absence) are individually consistent with
a distant climbing airliner imaged in IR — engine thermal bloom, a transient
aerodynamic contrail, and parallax — matching ADS-B data. CEFAA's 'unexplained'
verdict rested on a near-helicopter distance assumption the flight
reconstruction contradicts. Valuable as a cautionary instrumented case; filed as
a disputed optical artifact.
