Argentine Army Capitan UAP Physical Evidence 1965

On August 12, 1965, a large metallic disc hovered over the Duperial petrochemical complex and an adjacent Argentine Army garrison in Capitan Bermudez, Santa Fe Province. Approximately 150 witnesses including Army soldiers, garrison officers, and factory workers observed the disc at close range. Vehicle engines and electrical systems failed across a radius of approximately 400 meters. Compass readings became erratic. The disc was reported to emit a humming sound and a bluish-white glow before departing rapidly. Argentine Army intelligence conducted an official investigation, interviewing witnesses and documenting the zone of vehicle interference. The classified Argentine military report noted the simultaneous compass and vehicle interference as consistent with electromagnetic effects. US Embassy Buenos Aires forwarded a summary to the Defense Intelligence Agency. The case represents one of the most documented electromagnetic interference events in South American UAP history.
