Airship

Airship

Airship (飛行船)—also known as a “balloon ship” or “dirigible”—is a type of aircraft that uses a lighter-than-air gas (such as hydrogen or helium) to generate lift.
Unlike modern airplanes that rely on powerful engines to stay airborne, airships achieve flight by adjusting buoyancy and using
a propulsion system for movement and hovering.
The development of airships began in the late 19th century, and they became a significant form of air transport in the early 20th century.
They once played a prominent role in military operations, postal delivery, and commercial travel, marking an important chapter in aviation history.
