Explanation

A machine that can fly, held aloft in the air, is called an aircraft. Airplanes and helicopters are two types of aircraft. Some aircraft, such as helicopters, fly by using rotary wings — spinning blades that directly generate lift. Airplanes use engines to turn propellers or power gas turbines, providing the thrust needed to move air over their wings and create lift. Still other aircraft, including hot-air balloons, achieve lift through buoyancy, by using gases that are lighter than the surrounding air. Balloons and airships, including blimps and dirigibles, were actually the first vehicles referred to as aircraft, a term adapted from nautical terminology.
