115 years ago today, on March 28, 1910 (February 18, 1910 lunar calendar), the Frenchman Fabre successfully flew the first seaplane. A seaplane that can take off, land and park on the water. Referred to as a water plane. Water planes are divided into two types: hull type and pontoon type. The former has a special shaped fuselage designed according to the requirements of water taxiing, called the hull; the latter generally replaces the landing gear of the land plane with a pontoon. Hull seaplanes are further divided into single-hull type and double-hull type. Seaplanes are used in military maritime reconnaissance, anti-submarine and rescue activities, do not require runways, are flexible in use and have good maneuverability; in civilian use, they are mainly used for maritime rescue, maritime observation and sports. The disadvantages of seaplanes are: they cannot adapt to high-speed and supersonic flight, the fuselage structure is heavy, and the wave resistance performance requirements are high. The application of seaplanes at sea is increasingly replaced by carrier-based helicopters. On March 28, 1910, the Frenchman Fabre successfully flew the first seaplane.
