The Goodyear GZ-20/20A was a class of non-rigid airship or blimp introduced in 1969 by The Goodyear Tire and Rubber Company in the United States as its signature promotional aircraft, the Goodyear Blimp. The design is based on the previous Goodyear GZ-19 class. The GZ-20 featured a larger envelope to carry the "Super-Skytacular" advertising night sign and more powerful engines. The GZ-20s were the mainstay of Goodyear's airship operations until 2017, when they were replaced with the new Zeppelin NT semi-rigid airship.

Non-rigid airship in the context of Ballonet
A ballonet is an inflatable bag inside the outer envelope of an airship which, when inflated, reduces the volume available for the lifting gas, making it more dense. Because air is also denser than the lifting gas, inflating the ballonet reduces the overall lift, while deflating it increases lift. In this way, the ballonet can be used to adjust the lift as required.
Ballonets may typically be used in non-rigid or semi-rigid airships, commonly with multiple ballonets located both fore and aft to maintain balance and to control the pitch of the airship.
Non-rigid airship in the context of JMWAVE
JMWAVE or JM/WAVE or JM WAVE was the codename for a major secret United States covert operations and intelligence gathering station operated by the Central Intelligence Agency from 1961 until 1968. It was headquartered in Building 25 at the former Naval Air Station Richmond, an airship base in Miami, about 12 miles south of the main campus of the University of Miami on what is the university's present-day South Campus.
The intelligence facility was also referred to as the CIA's "Miami Station" or "Wave Station."
