Norwegian ethnographer and adventurer Thor Heyerdahl and his five man crew set out from Peru on a giant balsa wood raft called the Kon-Tiki in order to prove that Peruvian natives could have settled Polynesia. After a 101 day, 4,300 mile (8,000 km) journey, Kon-Tiki smashes into the reef at Raroia in the Tuamotu Islands on August 7, 1947, thus demonstrating that it is possible for a primitive craft to survive a Pacific crossing.
