One of the stranger abduction cases out of South America happened near Bahía Blanca, Argentina, in October of 1973.
The man at the middle of it all was Dionisio Llanca, a 25 year old truck driver hauling materials in an old Dodge truck when he had trouble with a tire along Route 3 in the middle of the night. Just a regular dude on a dead road, tools on the ground, truck pulled over, one tire giving him shit, and the headlights cutting through the dust.
According to Llanca, that is when a yellowy white light appeared in the distance. At first it looked like another vehicle coming down the road, which would have made sense. Then it stopped making sense. The light moved wrong, came closer, got stronger, and he said his body locked up. Paralysis. He described being unable to move. Then he saw the object: a disc shaped craft, low over the ground. Near it were three human like figures. Two men and one woman. Pale. Calm.
The story goes that they approached him, missing time, amnesia and confusion. Llanca was later found in Bahía Blanca, reportedly disoriented, with no clear memory of who he was at first, and he ended up in hospital care.
