Thor Heyerdahl is the famous Norwegian writer and explorer. In the 1940s he created an unbelievable theory that maybe could expand understanding of history of all mankind. So Heyerdahl stated that people from South America could have settled Polynesia in pre-Columbian epoch. At the times of Heyerdahl`s theory appearing there were not any scientists that believed in it, and its author was taken as crazy.
After this Heyerdahl decided to organize an expedition Across the Pacific Ocean. His aim was was to show, by using only the materials and technologies available to those people at the time, that there were no technical reasons to prevent them from having done so. Although the expedition carried some contemporary equipment, such as a sextant, radio, watches, charts, and tools from iron (knives and spoons).
The trip of raft called The “Kon-Tiki” began on April 28, 1947. Heyerdahl and five companions traveled by the raft for 101 days over 6900 km (or more than 4,300 miles) across the Pacific Ocean. Their raft was smashed into reefs nearby the Tuamotu Islands on August 7, 1947. Nevertheless, all team made successful landfall and everybody came back safely.
After this expedition Thor Heyerdahl wrote a book about his experience that soon became a bestseller. Firstly it was published in Norwegian in 1948 with the name “The Kon-Tiki Expedition: By Raft across the South Seas”, and later reedited as “Kon-Tiki: Across the Pacific in a Raft”. The book appeared with immense success in English in 1950, also in many other languages. A documentary film about the expedition, also called Kon-Tiki was produced from a write-up and expansion of the crew's filmstrip notes and won an Academy Award in 1951. We know one remarkable fact about creating of this film. While traveling on the Kon-Tiki Thor Heyerdahl and his colleagues filmed almost everything interesting. However, a considerable part of the filmed material was rejected, because all the crew… was naked!
