How one man visited every country on Earth without taking a flight

The World

Thor Pedersen, a former UN soldier originally from Denmark, went on a decadelong adventure that took him to every country in the world. The trick — he never took an airplane. By train, bus, boat and other forms of transport, he covered over 220,000 miles. He spoke with host Carol Hills this summer when he returned home to Copenhagen. (Originally aired Aug. 4, 2023.)
