Sikorsky S-38
From Wikipedia, the free encyclopedia
The Sikorsky S-38 was sometimes called "The Explorer's Air Yacht". Indeed, the S-38 was Sikorsky's first widely produced amphibious flying boat which in addition to serving successfully for Pan American Airways and the U. S. Army, also had numerous private owners who received notoriety for their exploits. Some famous owners include:
- Aviator Charles Lindbergh - Surveyed South American and Pacific Ocean routes for Pan Am with Anne Morrow Lindbergh.
- Newspaper publisher Robert R. McCormick - Surveyed commercial air routes between North America and Europe.
- Venture capitalist John Hay Whitney - Luxury Transport
- The Flying Hutchinsons - First attempted around the world flight by a family.
- Filmmakers Martin and Osa Johnson - In the zebra-striped S-38 "Osa's Ark", with companion giraffe-patterned S-39 "Spirit of Africa", explored Africa extensively, making safari movies and books.
- S. C. Johnson's Herbert Johnson - Explored South America in search of and to research the carnauba wax palm, the source of the world's hardest natural wax. The "Spirit of Carnauba", a replica of this aircraft, exists and is flying today.
One of the two remaining S-38s, N-28V, appears in the movie The Aviator; Hughes actually flew an S-43.
The Navy and Marine designation for this aircraft was RS-3.
A total of 90 (or possibly 101, sources disagree) aircraft were built, manufactured by the Sikorsky Aircraft Company in Stratford, Connecticut. Sikorsky was acquired by United Aircraft and Transport Corporation (now United Technologies Corporation) in mid-production. The aircraft first flew in May 1928.
