Zeppelin

A Zeppelin is a type of airship or balloon that is filled with a lighter-than-air gas, like helium or hydrogen, to lift it into the sky. Characterized by its elongated shape and rigid structure, the Zeppelin is often associated with early 20th-century aviation. They were used for passenger travel and cargo transport, as well as in military applications. Though their popularity declined after accidents like the Hindenburg disaster, Zeppelins remain a symbol of innovation in air travel and are still used today for advertising and sightseeing.
