Amphibious planes are aircraft designed to take off and land on both water and land. They have special features, such as floats or hulls, that allow them to float on water while also being equipped with wheels for landing on runways. This versatility makes them useful for various purposes, including search and rescue missions, tourism, and transportation in remote areas. These planes are often used in regions with many lakes or rivers, where traditional runways may not be available. Notable examples of amphibious planes include the Dornier Seastar and the Grumman G-21 Goose, which showcase the unique capabilities of this type of aircraft.
