Thor Heyerdahl, the Norwegian explorer famed for his 1947 Kon Tiki raft expedition across the Pacific, addresses media in September 1970 in Amsterdam harbor in front of "Ra II", a 12 meter replica of an ancient vessel made of papyrus, after his expedition across the Atlantic Ocean. A film made about Heyerdahl's expedition was nominated in the Best Foreign Film category for the 2013 Oscars.
