Quilino, Arg landing encounter — August 20, 1957

On August 20, 1957, at Quilino in Córdoba, Argentina, a witness reported a saucer-shaped object descending rapidly. A voice was then heard offering reassurance and claiming that the visitors had a base in the Salta region. The object subsequently departed rapidly toward the north. The account was cited in Flying Saucer Review and Loren Gross's history of 1957 sightings. It describes the perceived voice and the object's movements, without identifying a visible speaker or reporting that the witness entered the craft.
