Iquique Air Base UAP Formation

A Public Sky

On the afternoon of November 5, 2010, the Chilean Air Force held a small air show at the El Boco airfield outside Iquique to mark the change of command of the regional Combat Group VI. The event was modest by international standards — a handful of dignitaries, family members, and aviation enthusiasts gathered along the runway as a flight of Halcones aerobatic team aircraft, the Air Force’s F-5E Tiger III display unit, performed a low pass overhead. Several spectators recorded the pass with consumer video cameras. Two of those recordings, when reviewed in slow motion days later, showed a small object overtaking the formation from behind, traversing the camera frame in a fraction of a second, and continuing northward at a speed that no contemporary aircraft, missile, or ballistic projectile readily explained.

The Iquique footage would have remained a local curiosity but for two factors. First, the aircraft involved were Chilean military, and the formation’s pilots had no awareness of any object passing through their flight path during the manoeuvre. Second, Chile possessed, almost uniquely in South America, an official body charged with examining such cases — the Comité de Estudios de Fenómenos Aéreos Anómalos, or CEFAA, housed within the Directorate General of Civil Aeronautics. The Iquique case was referred to CEFAA shortly after the videos surfaced.

The Investigation

CEFAA’s chief investigator, retired General Ricardo Bermúdez, assembled a multidisciplinary panel including astronomers from the University of Chile, photographic analysts from the national police laboratory, and aerodynamicists from the Air Force itself. The panel obtained the original camera files, examined the EXIF metadata, calibrated the imagery against known dimensions of the F-5E airframe, and compared the object’s apparent trajectory to radar logs from the Iquique-Cavancha approach control. Their analysis, summarised in a report delivered to the CEFAA scientific committee in 2012, made several determinations that have been widely cited and partially contested.

The object, on frame-by-frame analysis, traversed the camera’s field of view in roughly one-thirtieth of a second at an angular rate consistent with an estimated speed of between 4,000 and 10,000 kilometres per hour at the inferred distance behind the formation. It accelerated visibly across the brief observation window. It executed a slight directional change, ruling out a ballistic projectile. It returned no air traffic control signature, and the Iquique radar tape showed no corresponding return at the relevant time. Birds, insects, and camera artefacts were excluded by the presence of the object in two independently filmed sequences. CEFAA’s eventual conclusion, after repeated review, was that the object met the formal criteria for a true unidentified aerial phenomenon.

Public Disclosure

In October 2012, Bermúdez and the CEFAA panel publicly released a portion of their findings at a Mutual UFO Network Symposium in Cincinnati, Ohio, and shortly afterwards through Chilean media. The decision to share the data internationally was unusual for a state body and reflected CEFAA’s stated mission of treating UAP as an aviation safety question deserving of open scientific exchange. The disclosure included high-resolution stills, the full motion files, and the panel’s procedural reasoning.

International reception was mixed. Several aerospace researchers, including the French CNES-affiliated investigator Jean-Jacques Vélasco, supported the panel’s conclusions. Skeptical analysts proposed alternative explanations including high-altitude weather balloons, military drone tests undertaken without local notification, and image-compression artefacts producing apparent acceleration. The CEFAA panel addressed each of these proposals in a follow-up technical note in 2013, finding none of them adequate to the full set of observations. The case remained classified within CEFAA’s records as unidentified.

Context Within Chilean UAP Records

The Iquique case is not isolated. CEFAA has, since its founding in 1997, accumulated a substantial dossier of military and civilian aviation reports including the El Bosque Air Show case of 2010 — recorded earlier the same year over Santiago — and a series of naval and helicopter incidents through the 2010s. Chilean military culture has, broadly, accepted the legitimacy of UAP reporting in a manner not always paralleled in neighbouring countries, a posture often credited to the long institutional history of CEFAA and to Bermúdez’s personal advocacy for transparent scientific examination.

What distinguishes Iquique within this body of cases is the combination of multiple cameras, the presence of military aircraft as a known reference object, and the absence of any subsequent claim of responsibility by drone operators, balloon clubs, or experimental aircraft programmes. The case has been cited in international UAP literature as an example of the kind of well-documented incident that, if adequately replicated and shared across national systems, might form the basis for the global aviation-safety framework that researchers such as Avi Loeb and the Galileo Project have proposed.

Continuing Significance

In the years since, the Iquique footage has continued to surface in popular media, often presented without the methodological context that CEFAA provided. The original analysis remains accessible through the agency’s archives and through the Chilean Air Force’s institutional library. CEFAA itself has experienced periodic budgetary challenges; its scientific committee was reconstituted in 2019 and again in 2022, and its current operational status reflects the volatility of Chilean civil aviation policy.

The pilots of the Halcones formation, interviewed in subsequent years, have consistently said that they perceived nothing during the pass and learned of the incident only when the videos circulated. The object, whatever it was, completed its traversal and vanished beyond the camera’s reach. The runway returned to its ordinary uses. Above the Atacama, at speeds the recording barely captured, the unexplained had again briefly intruded upon the public sky.
