Honolulu Clipper was the prototype Boeing 314 flying boat designed for Pan American Airways. It entered service in 1939 flying trans-Pacific routes. Like other long range Clipper aircraft in Pan-Am it aided US military during World War II. In service with the US Navy it made a forced landing 650 miles east of Oahu on 3 November 1945 and when the subsequent salvage attempt was abandoned, the Honolulu Clipper was deliberately sunk by gunfire.
