Quick Summary

Aerostatic craft are a type of aircraft that rely on buoyancy to fly, meaning they are lighter than the air they displace. This category includes balloons, nonrigid airships (blimps), and dirigibles. Balloons are filled with hot air or lighter-than-air gases like helium or hydrogen to achieve lift. While balloons drift with the wind, airships are steerable and have propulsion systems. Dirigibles, though no longer in use, were also lighter-than-air craft with rigid structures. Aerostatic craft are distinct from heavier-than-air aircraft, which generate lift through aerodynamic forces created by movement.123

The most successful of these air-cushion vehicles (ACVs) is the British-made Hovercraft. It is used commercially as a passenger- and car-carrying ferry; a number of them ply the English Channel. Experimental “tracked skimmers” (air-cushion trains) are under development in a number of countries, but they are not yet used commercially…
