One guy was born in the fifties, after his mother had a historectomy. He talked of a lot of things, including his father, who was from a star-system called Palades, or something similar. In Vietnam, when he was sent with 11 others to assassinate the N. Vietnam leader, something happened and they all died. He then remembers laying on an operating table, supposedly the aliens had picked him up (his half-family). Ten days after the ordeal, he was found in a rice paddy by U.S. soldiers. They said he has an extra vertebrae and an extra rib.
