Charley rides his motorcycle to North Carolina, where he takes to the air in a replica of the Wright brothers' historic biplane and dives to the wreck of a First World War U-boat scuttled by the Germans when they realised the war was lost. In Charlotte, he learns about the War of Independence and gets to grips with firing a traditional musket, before heading to the Chattooga River in South Carolina, the location where his father John filmed 1972 thriller Deliverance
