Airships move primarily through the use of buoyancy and propulsion. They are filled with a lighter-than-air gas, such as helium or hydrogen, which allows them to rise. For horizontal movement, airships are equipped with engines and propellers that generate thrust, enabling them to steer and navigate through the air. The combination of buoyancy for altitude control and propulsion for forward movement allows airships to travel efficiently.
The most famous airships are Hendenburg and Zeppelin.
