Brit adventurer back on UK soil after 28-year round-the-world walk

British adventurer on a 50,000-kilometre, 28-year trek home from South America without using any transport has set foot on UK soil after swimming the Channel, his publicists said Tuesday. Karl Bushby, a 57-year-old former paratrooper, set off from Punta Arenas, Chile, in November 1998, vowing to reach his mother’s home near Hull in northern England without travelling on planes, trains, boats, vehicles or other transport modes.
