blimps

     

A non-rigi airship, or blimp, differs from a rigid airship (e.g. a Zeppelin) in that it does not have a rigid structure that holds the airbag in shape. Rather, these aircraft rely on a higher pressure of the gas (usually helium) inside the envelope. Although a blimp can be steered and thus qualifies as a dirigible, that term is more commonly used with rigid airships.
