Flying Boat

A flying boat is a type of fixed-wing seaplane whose fuselage itself is shaped as a hull capable of floating and landing on water, distinguishing it from a floatplane, which instead relies on separate pontoons attached beneath an ordinary airframe; many flying boats also use small wing-mounted sponsons for added stability on the water. The type dominated international long-distance aviation from the 1920s through the 1940s, pioneering the first transatlantic air routes at a time when reliable, long land-based runways were not yet widely available, with aircraft such as the Boeing 314 Clipper and the Short Empire offering the range and comfort that made distant destinations reachable by air, and military flying boats including the PBY Catalina, of which more than 2,661 were built, and the Short Sunderland serving widely as patrol aircraft. Flying boats declined rapidly after the Second World War, once wartime construction had left many countries with long paved runways, removing the water-landing advantage, while landplanes such as the Lockheed Constellation and Douglas DC-4 matched their speed and range without a flying boat's more demanding pilot training.
