Zeppelins, while historically significant in aviation, are generally considered safe today when modern safety standards and materials are applied. Early zeppelins (rigid airships) had major safety issues, most notably the use of flammable hydrogen gas, which contributed to catastrophic accidents such as the Hindenburg disaster in 1937. Modern airships (including zeppelins) use non-flammable helium, advanced materials, and improved engineering, making them much safer for contemporary applications such as advertising, observation, and tourism.
