From the Archives: Tristan Jones On Adventuring After the Loss of His Leg.

Adventurer and author Tristan Jones. Tristan Jones is almost certainly the most intrepid sailor alive. At last count he's journeyed more than 450-thousand miles in small boats. That includes 20 crossings of the Atlantic, and 3 and a half circumnavigations. Many of those miles were racked up during the course of exceedingly dangerous, some would say foolhardy, adventures. Jones tried to sail as close as possible to the North Pole, and as a result spent a year frozen in the Arctic ice pack.

Cleland was a decorated Army veteran who lost three limbs while serving in Vietnam. After the the war, he dedicated his life to public service. He died Nov. 9. Originally broadcast in 2009.
