Caso Bariloche (1995)

The night of 31 July 1995

On the evening of 31 July 1995, an Aerolíneas Argentinas Boeing 727 was making its approach to Bariloche airport in Río Negro province, in the Andean foothills of Patagonia. According to the captain, Jorge Polanco, a bright light appeared near the aircraft and stayed with it for roughly 15 to 17 minutes; accounts differ on the exact duration and times. Polanco said the object intercepted the airliner and forced him into a high-risk evasive maneuver during the final approach. The aircraft was reported to carry about 100 passengers and a crew of three.

The approach coincided with a general power failure that left the city and airport dark. That detail is central to the case: the darkness is what made a single bright light stand out, and it is also the context in which the official explanation was later built.

Witnesses and reports

The sighting was not limited to the cockpit. A Gendarmería Nacional medical flight in the area, flown by Commanders Rubén Cipuzak and Juan Domingo Gaitán, also reported the light, and airport chief Daniel García logged events from the control tower. Some 1995 press accounts add that airport instruments behaved erratically and that the lights around the airport went out as the object departed. The story was carried by Argentine and French newspapers in the first days of August 1995.

Official investigation and the 2018 explanation

The case remained a reference point in Argentine ufology for two decades. In 2018 the Argentine Air Force investigation concluded the sighting was the result of confusion: a person reportedly aimed a powerful projector at the cloud base as the airliner approached the dark airport, and that beam was taken for an object. The conclusion was that the phenomenon had a terrestrial, non-extraterrestrial origin.

The official file stayed closed until 2020. After a request from civilian researcher Pablo Álvarez and the CEFORA civilian study commission, the Ministry of Defense released the investigation file in mid-September 2020; the file is dated 9 September 2020 (case number 2020-60053899-APN-DNAIP#AAIP) and includes transcripts of communications between the control tower and both crews. CEFORA described the release as the first official declassification of the case.

Assessment

The case is best described as contested rather than unexplained. The strongest official position is the 2018 projector explanation, which accounts for a light, a blackout, and an approach with no obvious contradiction in the public summaries. The UFO interpretation rests mainly on the crew testimony, the number of witnesses across several agencies, and the duration of the event; the projector explanation has to account for a light that, by the crew's account, tracked the aircraft while it changed course.

What the record supports is narrower: an airliner crew reported a serious, sustained event with a light during a blackout, the Argentine state investigated it, and the state's conclusion was a terrestrial cause. Anyone reading the case should note that the full file was published only in 2020, twenty-five years after the event, and that most public detail still comes from press summaries and the CEFORA statement rather than from independent analysis of the transcripts.

The case also illustrates a common pattern in official UAP reviews: a witness report built on a few minutes of observation, a plausible local cause, and a gap between what the crew felt they saw and what a ground-based explanation can demonstrate. Whether that gap is significant depends on how much weight one gives to the crew's professional judgment, and on whether the projector explanation was tested against the tower logs and instrument readings.
