Sikorsky’s first attempt to build an amphibian, the six-seat S-34 NX883, flew in 1926. During a test flight in November 1927, piloted by Capt. Collier and with Igor Sikorsky as observer, it developed engine trouble while flying low over water and sank after forced landing. The two men were rescued and taken ashore by motor boat.
