But their assignment to a place in the national defense arouses questions...." "A blimp, or 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 the lifting gas (usually helium, rather than hydrogen) inside the envelope and the strength of the envelope itself to maintain its shape. The term is sometimes also used to refer to the tethered craft properly known as moored balloons. While often very similar in shape, moored balloons have no propulsion and are tethered to the ground." (from Wikipedia). Very Good+ in Good dust jacket .
