After World War I, civil aviation came to the forefront. Designers and manufacturers also created aircraft that was capable of landing on and taking off not only dry land, but water too.
In the late 1910s - early 1920s the Italian Savoia-Marchetti factory built several successful models. Their innovative S55 model entered service in 1925. The German Dornier Do-X flying boat, powered by 6 engines, each of 525 hp, could carry 158 passengers with a crew of 11.
The heyday of ´flying boats´ was the 1930s. After the Hindenburg disaster, passenger and freight transportation was carried out by flying boats all over the world. There were several types for passenger traffic, freight transportation, research or military purposes. The years following World War II brought a new era in the history of flying boats. With the appearance and spread of long-range airplanes, flying boats became marginalized. However, today this type of aircraft plays an important role in the life of islands, lakes and rivers.
