San Carlos de Bariloche Close Encounter Case
The San Carlos de Bariloche close encounter case is one of the most famous aviation UFO incidents in Argentine history. It is generally identified with the 31 July 1995 encounter involving captain Jorge Polanco of Aerolíneas Argentinas as his aircraft approached Bariloche airport during a winter-night power outage. The case became famous because it appears to combine several features that make an air-safety UFO report unusually durable:
- a named commercial pilot
- a second aircraft crew from Gendarmería Nacional
- airport tower and ground witnesses
- a major electrical failure over Bariloche
- recorded radio communications
- later declassification of case documents
- and a formal Air Force explanation that many researchers still dispute.[1][2][3][4][5][6]
Within this encyclopedia, the case matters because it sits at the intersection of aviation safety, official records, and competing interpretations. Unlike a simple light-in-the-sky story, Bariloche became a full “incident file.”
Quick case summary
In the standard version of events, Jorge Polanco was flying an Aerolíneas Argentinas Boeing 727 toward San Carlos de Bariloche on the evening of 31 July 1995. During the descent phase, after the airport reported a power failure, he saw a bright light ahead of the aircraft that seemed to move onto a collision path, stop nearby, and then pace the plane during approach. Polanco later described the object as disc-like, with green lights and an orange central light. At the same time, a Gendarmería Nacional aircraft in the area, plus tower and airport personnel, also reported unusual lights.[1][2][5][6][7][8]
That is what made the case famous:
- a commercial airliner on approach
- an apparently structured luminous object
- multiple aviation witnesses
- and a dramatic operational context involving blackout and aborted landing.[1][2][5][6]
Why this case matters in UFO history
The Bariloche case matters because it is one of the best-known South American pilot encounter reports of the 1990s. It is often treated as a strong example of a near-aircraft UFO incident, especially because the case did not remain only in rumor or tabloid retelling. It generated interviews, statements, and eventually declassified material.[1][3][4][9]
It is historically significant because it combines:
- a professional airline pilot
- corroboration from another aircraft crew
- an airport control context
- a long media afterlife
- and an official resolution that did not persuade everyone.[1][2][3][5][6]
That unresolved split is the main reason the case survived.
Date, time, and flight-number confusion
The core incident is consistently placed on 31 July 1995, but there is some drift in later public retellings regarding the exact time window and the flight number. Some sources identify the aircraft as AA 674, while others later call it flight 734. The event is generally placed between about 20:00 and 21:00 local time, with the most cited operational interval during the blackout running roughly from 20:17 to 20:31.[1][2][5][6][7][8]
This is worth noting because it shows how even a well-known case can accumulate small documentary inconsistencies over time. The stable historical core is the Polanco / Bariloche approach incident, not every secondary numerical detail.
The blackout over Bariloche
One of the most important features of the case is the citywide power outage. Multiple later reports say that Bariloche and surrounding areas lost power, that the airport switched to emergency generation, and that the blackout coincided with the core phase of the incident. The local press also tied the outage to protectors tripping at a substation carrying power from Alicurá.[5][6]
This matters because the blackout shaped the witnesses’ interpretation in several ways:
- it made the sky scene more dramatic
- it complicated the landing environment
- it increased stress in the cockpit and tower
- and it later became part of the Air Force’s conventional explanation.[5][6][10]
In other words, the blackout is not just background. It is part of the case structure.
Jorge Polanco’s account
Polanco is the central witness. In later interviews he consistently described seeing a bright light ahead of the aircraft during approach, then a more structured object pacing or crossing relative to the aircraft. He later described it as roughly 30 meters across, like an inverted soup plate, with green lights on the sides or edges and an orange light on top or in the center that seemed to pulse or “breathe.” He also said he had to perform an escape maneuver under difficult conditions because the object and the blackout made continuing the approach unsafe.[5][6][7][8]
This matters because Polanco’s testimony is not vague. Whether one believes him or not, he gave a stable, strongly visual description over time.
The crew and cabin context
Later reporting says that the cockpit also included copilot Carlos Atilio Dortona, flight engineer Jorge Allende, and, in some retellings, another airline commander visiting the cockpit. Polanco later said his colleagues were overwhelmed or blocked by the event, leaving him to manage the maneuver largely on his own. At least one passenger account published later described a strong jolt and the announcement that the aircraft had to circle because of the power outage, though the passengers generally did not see the object itself.[2][6][7]
This is an important distinction:
- the close visual encounter is a cockpit-and-airfield case
- the passenger experience was mostly the operational disturbance, not the object itself.[6][7]
The Gendarmería aircraft
A major reason the case remained strong in ufology is the reported corroboration from a Gendarmería Nacional aircraft, often described as a Piper PA-31T Cheyenne. The two most frequently cited witnesses from that aircraft are Juan Domingo Gaitán and Rubén Cipuzak. Later summaries quote Gaitán describing an amber light over Nahuel Huapi moving rapidly toward the cordillera, and Cipuzak is widely quoted as radioing Polanco that he could see a light to the right of the airline aircraft and did not know what it was.[2][5][6]
This second-aircraft corroboration matters a great deal. Without it, the case would be much easier to dismiss as a single-pilot misperception.
The tower and ground witnesses
According to declassification coverage and later case summaries, the event was also observed or operationally followed from the tower, with Daniel García often identified as the airport chief on duty, and other personnel from meteorology, the runway, and the airport service environment also becoming part of the witness tradition.[1][2][3][5]
This does not mean every one of those witnesses saw the same thing in the same way. But it does mean the case spread across multiple roles:
- airline cockpit
- Gendarmería cockpit
- tower
- ground service area
- and airport operational staff.[1][2][3][5]
That multi-role spread is one reason the case remained hard to reduce to “one person saw something strange.”
The radio exchanges
One of the strongest documentary aspects of the case is the existence of radio communication transcripts or declassified transcriptions discussed in 2020 reporting. Later coverage published excerpts and summaries of communications between the aircraft and the tower, including the repeated references to the light’s relative position and movement. This gave the Bariloche case a documentary quality beyond memory alone.[1][6]
That does not prove extraterrestrial origin. But it means the incident had a communications record, which is a very different evidentiary profile from most classic civilian UFO stories.
The duration problem: 15 minutes or 17 minutes?
A small but important ambiguity in the case is duration. Some retellings say the event lasted about 15 minutes, others 17 minutes. This appears to reflect the difference between a rounded public estimate and Polanco’s own later phrasing. The broader point remains the same: the event was not experienced as a one-second flash. It unfolded over a meaningful segment of flight operations.[4][5][6][7]
That operational duration is one of the reasons the case feels more serious than a brief visual anomaly.
The shape and behavior of the object
The object is usually described as:
- luminous at first
- then more clearly disc-like
- maneuvering in relation to the aircraft
- able to stop, pace, or reposition rapidly
- and finally disappearing at speed toward the Cerro Otto / Nahuel Huapi area in later retellings.[5][6][7][8]
Believers point to those motion claims as the strongest sign that the object was not a normal light or aircraft. Skeptics argue that relative-motion confusion during approach, cloud-base reflection, and expectation under stress can dramatically distort how movement is perceived at night.[9][10]
The official Air Force explanation
One of the biggest later developments was the Argentine Air Force / CEFAE resolution published in 2018. That report argued that the observed “OVNI” positions coincided with a powerful sky-tracing spotlight or reflector aimed at the cloud base during the blackout. According to the report, researcher Heriberto Janosch had previously developed that line of inquiry, and later CEFAE work connected the observations to a reflector being tested by Juan Carlos Rivero near a discotheque, under exactly the meteorological conditions that could produce dramatic moving reflections on low cloud.[9][10]
This explanation is central to the modern case. It is not a generic debunk. It is a specific reconstruction:
- blackout
- cloud layers
- two aircraft in a confusing geometry
- and a ground-based spotlight projected into the clouds.[9][10]
Why many researchers reject the reflector explanation
The reflector theory did not settle the case for everyone. CEFORA and sympathetic researchers argued that the official resolution relied too heavily on reconstruction and did not fully account for the testimony of the pilots and other witnesses. They especially objected to what they saw as witness manipulation, timing mismatches, and the attempt to compress a complex aviation event into a single lighting explanation.[3][11]
For critics of the official solution, the key objections are:
- trained pilots described a structured object, not just a reflected spot
- the Gendarmería crew also reported unusual behavior
- the incident involved operational consequences, not just visual confusion
- and the blackout itself may have obscured rather than explained the anomaly.[3][4][11]
This is why the case remains open in public memory even after an official resolution was published.
Why believers find the case persuasive
Supporters of the Bariloche case usually emphasize:
- Jorge Polanco’s professional background
- corroboration from the Gendarmería crew
- tower and airport personnel involvement
- the documented blackout
- the communications record
- and the claim that the object behaved in ways no spotlight reflection should.[1][2][3][5][6][7]
For believers, this is one of Argentina’s strongest examples of a true air-safety UFO encounter.
Why skeptics push back
A strong encyclopedia page has to take the skeptical side just as seriously.
The skeptical objections include:
- the event happened at night under unusual cloud conditions
- the blackout and emergency procedures increased stress and ambiguity
- the later official reconstruction produced a concrete conventional mechanism
- witness narratives became richer over time in interviews and media retelling
- and some details, such as exact duration and flight number, drift across sources.[6][9][10]
This does not make the case trivial. But it does mean it is not a clean, one-direction evidentiary story.
Was this really a close encounter?
In a broad UFO-classification sense, yes. The case belongs in a close-encounter archive because the object was reported at relatively close range to an aircraft in a potentially hazardous operational context. More narrowly, it is best described as an aviation close encounter / airmiss-type case, not a humanoid case, not a landed-craft case, and not a physical-trace case.[5][12]
That distinction matters. Bariloche is important because of proximity and operational consequence, not because of beings or ground traces.
Why the case remains unresolved
The Bariloche case remains unresolved because its strongest features pull in opposite directions.
On one side:
- it has named aviation witnesses
- a second aircraft
- tower and ground involvement
- declassified records
- and a lasting reputation in Argentine aviation UFO lore.[1][2][3][5][6]
On the other side:
- there is a formal official explanation
- that explanation is detailed rather than generic
- and the case’s strongest dramatic details come from later retellings and interviews, not only from raw operational record.[7][9][10]
That balance between strong witness structure and plausible official reconstruction is exactly why the case survives.
Cultural legacy
The Bariloche / Polanco incident became one of the most famous UFO episodes in Argentina. It has survived through:
- national newspapers
- local Río Negro coverage
- television interviews
- declassification campaigns
- CEFORA advocacy
- and later anniversary retrospectives.[1][2][3][4][5][6][7][8][11]
It is now one of the key Argentine reference cases whenever pilot encounters or official UFO files are discussed.

Frequently asked questions
What happened in the San Carlos de Bariloche close encounter case?
On 31 July 1995, during approach to Bariloche, captain Jorge Polanco reported that a bright structured object approached and accompanied his Aerolíneas Argentinas aircraft. A Gendarmería crew, tower personnel, and others were also later linked to the event, which unfolded during a major power outage.[1][2][5][6]
Who was Jorge Polanco?
He was the Aerolíneas Argentinas captain at the center of the incident and later became the most famous public witness associated with the Bariloche case.[5][6][7]
Were there really other aviation witnesses?
Yes. The most frequently cited additional witnesses were Gendarmería crew members Juan Domingo Gaitán and Rubén Cipuzak, as well as airport personnel including Daniel García.[1][2][3][5][6]
What is the official explanation?
The Argentine Air Force’s 2018 CEFAE report argued that the observed “OVNI” positions matched reflections of a powerful sky-tracing spotlight aimed at the cloud base during the blackout, rather than an unknown craft.[9][10]
Why do some researchers reject that explanation?
Because they argue the reflector theory does not fully account for the pilots’ descriptions, the multi-witness structure of the case, and the operational seriousness of the encounter.[3][4][11]
Editorial note
This encyclopedia documents the San Carlos de Bariloche close encounter case as one of Argentina’s most important aviation UFO incidents. It should be read carefully. The case is stronger than an ordinary sighting because it includes named pilots, a second aircraft, tower involvement, declassified records, and a sustained public history. But it is also weaker than its strongest supporters sometimes suggest, because a detailed official reconstruction exists and several key details drift in later retellings. That tension between strong testimony and strong counter-explanation is exactly why Bariloche remains in the archive.
