The 16-year old witness and a friend were playing "pelota" outside an automobile factory (where he worked) when, surprised by a vivid light, they turned around and saw a craft about 5 meters wide hanging nearby, a few inches off the ground. Near the object stood two short entities. These little men were about 1.20 meters in height, with oblique blue eyes, a penetrating gaze, and wearing gray clothing with a sort of emblem on the chest area. The heads were totally bald, but of what would be a normal size on a larger being. They then heard a voice addressing them, in perfect Spanish, though no lip movement was detectable on the entities, and the voice sounded rather "like coming from some apparatus." Among the things he was told was that these beings were from another world and were here "to prepare people for a new cosmic race." The voice also foretold certain events that the young man said had indeed come about. After about 20 minutes the entities moved toward the craft and vanished into thin air. He main witness suffered from seizures soon after the incident.
