Despite serious injuries in the head, he thought with clarity to keep himself alive.

A Bolivian salesman was rescued in the Amazon jungle on Friday, almost three days since he figured in a plane crash that killed eight people on board.

Minor Vidal, a 35-year-old pharmaceuticals and cosmetics salesman, was the lone survivor in the crash. He was traveling on an Aerocon flight from Santa Cruz, Bolivia to Trinidad in the Amazon when the plane plummeted in the jungle on Tuesday night.

A Reuters report quoted Naval Captain David Bustos, who led the rescue operation: "From several kilometers away, we saw a man on the river bank signaling to us. When we got closer, he knelt down and thanked God."

"He said he'd been trapped in the plane for more than 15 hours and that when he finally escaped he began to walk and survived by drinking his own urine and water from a lagoon," Bustos added.

Bolivian newspaper La Razon reported Vidal, for the next 62 hours since the crash, stayed alive by eating insects, drinking his own urine and painting an arrow in the ground with his own blood to show rescuers where he was.

Vidal said he was seated in the back of the plane and was trapped in the wreckage. He was seriously injured in the head and the ribs but remained conscious. He told the press he used skills learned from his Boy Scout days and while pursuing his passion for camping and fishing.

Vidal filtered water through his clothes so that he could drink it, then he looked for an open space by a lagoon where he waited for his rescuers.
