Pajasblancas Airport (Argentina) — May 1, 1957 (0700)
When his motor- cycle suddenly failed, the driver observed a disk, 20 m in diameter and 5 m thick, hovering about 15 m above ground. He hid in a ditch and saw the craft come down, making a sound similar to air escaping from a valve. A sort of lift descended from its base almost to the ground. In it was a man of average height, who made friendly gestures to the witness. He was dressed in a plastic diving suit. The witness entered the ma- chine and saw inside several people seated before instrument panels, lighted by an extraordinary light. He was then escorted out, and the disk rose to the northwest. During the next hour, six sightings were made along the same course by independent witnesses. (Humanoids 35, FSR 65, I; FSR 65, 4)
