An Air Force man inside a tent heard a loud, shrill sound and saw a disk that came down as grass and plants fluttered wildly under it. He found himself unable to draw his gun, which "seemed to be glued in its holster." A voice came from the craft, telling him in Spanish that UFO's had a base in the Salta area and would soon show themselves to warn all people about the dangers of a nuclear catastrophe.

One saucer was observed by one male military witness at a military facility for over 18 minutes.
