Sign in to savethumb|right|300px|Goodyear GZ-20|The Spirit of Goodyear, one of the iconic [[Goodyear Blimps]] A blimp, (/blɪmp/) less commonly called a non-rigid airship, is an airship (dirigible) without an internal structural framework or a keel. Unlike semi-rigid and rigid airships (e.g. Zeppelins), blimps rely on the pressure of their lifting gas (usually helium, rather than flammable hydrogen) and the strength of the envelope to maintain their shape. Blimps are known for their use in advertising, surveillance, and observation due to their maneuverability, slow speeds and steady flight capabilities.
