Flying boats are a type of aircraft designed to take off and land on water. They have large, buoyant hulls that allow them to float, making them suitable for operations in areas without runways. These aircraft often have wings that extend from the hull, providing lift during flight. Historically, flying boats were used for passenger transport, military missions, and cargo delivery. Notable examples include the Consolidated PBY Catalina and the Dornier Do X. While their popularity declined with the advent of land-based planes, flying boats remain an important part of aviation history.
