Bariloche UFO Incident

The Encounter

On the morning of July 31, 1995 (local time August 1, just after 01:30), Aerolíneas Argentinas Flight 674—a Boeing 727 carrying 102 passengers and 3 crew members—approached San Carlos de Bariloche in Argentine Patagonia for landing after a flight from Buenos Aires. Captain Jorge Polanco, an 18-year veteran of Aerolíneas Argentinas, was commanding the aircraft when his crew spotted an unusually bright light ahead of the plane during final descent. What followed was one of the most credible mass-witness aviation encounters in modern UFO history.

The Sighting

Polanco reported that the luminous object appeared to "rush at" the aircraft but abruptly decelerated and maintained position approximately 100 meters from the plane. The object remained visible and paced the flight for 17 minutes—long enough for nearly all 102 passengers to observe it and for the event to be tracked by ground personnel. The light exhibited intelligent maneuvering, appearing to respond to the aircraft's position and trajectory. Controllers at Bariloche airport—Gerardo Giménez and Javier Mayorga—tracked the incident from their position in the tower, providing independent corroboration of the timeline and events.

Ground Effects and Corroboration

The electromagnetic signature of the encounter was unmistakable. During the 17-minute encounter, Bariloche experienced a city-wide power failure, described in contemporary press accounts as occurring "at the same time" as the sighting. At the airport itself, all recording and measuring apparatus suffered jamming, and tower instruments registered magnetic alterations for several seconds during the encounter. Multiple residents in the Bariloche area reported visual observation of the object coinciding with the power outage, creating a chain of independent ground witnesses beyond the aircraft. This convergence of evidence—visual testimony from trained aviators and civilians, electromagnetic effects at a sensitive facility, and corroborating ground control data—distinguishes the Bariloche case from purely anecdotal sightings.

Credibility and Impact

The incident's credibility rests on several factors: Polanco's professional standing as a long-serving airline captain; the presence of 102 civilian witnesses with no financial incentive to fabricate; independent airport controller testimony; measurable electromagnetic interference at airport facilities; and the power failure documented in municipal records. The case attracted enough institutional attention that it was subsequently referenced in Pentagon Unidentified Anomalous Phenomena (UAP) files, confirmed in a 2026 Buenos Aires Times report on newly declassified U.S. government documentation. This later inclusion suggests that U.S. intelligence agencies had compiled and assessed the Bariloche data as part of their systematic cataloging of foreign aviation/military encounters with anomalous phenomena.
