Are airships dangerous?
Zeppelins are most commonly linked with the Hindenburg accident in 1937. That airship used hydrogen as its lifting gas, and lacquer materials in the fabric of its hull, which contributed to the explosion. Airships today use non-flammable helium, a gas that is safe enough to be used in party balloons. The Zeppelin-NT also features a tear-proof outer envelope composed of high strength, multi-layer fabric, and has an unmatched global safety record – carrying more than 80,000 passengers since August 2001, without a single incident.
