The Story of Sir Robin Knox-Johnston. It is a 56-minute documentary about possibly the most famous sailor in modern times, Sir Robin Knox-Johnston, who was the first man to sail non-stop and alone around the world back 1969: On the 50th anniversary of his achievement this year, this is the remarkable story of Knox-Johnston's voyage around the world, and into history. From battling through monster waves, to being "lost at sea" after losing his radio, and fighting off a shark, Sir Robin relieves the journey and shares never before seen photographs and diary entries. We also hear about his achievement from fellow sailors Sir Ben Ainslie, Dee Caffari and Alex Thompson who put his voyage into perspective with the moon landings, plus adventurer Sir Ranulph Fiennes, and long-time friend, the BBC's John Simpson. We look back on his remarkable life, his career, his legacy and his astonishing influence on the sport, having just turned 80 years old.
