The Bariloche Aviation Incident (1995)
On July 31, 1995, as Aerolíneas Argentinas flight AR 674 approached San Carlos de Bariloche, Patagonia, a sudden power outage plunged entire neighborhoods of the city and its airport into darkness. The incident is documented in a report by the French study group COMETA and appears among the files reviewed by the Pentagon in its released archives on unidentified aerospace phenomena.
