Metal-clad Airship
Metal-clad airships are airships which have a very thin airtight metal envelope, rather than the usual fabric envelope. This shell may be either internally braced as with the designs of David Schwarz, Dooley A.193 (1893 airship never flew, but the 1897 flew at Berlin) or monocoque as in the ZMC-2. Only four ships of this type are known to have been built, and only two actually flew: Schwarz's aluminum ship of 1893 Dooley, A.185-A.186 citing Robinson, pp2-3 collapsed on inflation; Schwarz's second airship flew at Tempelhof, Berlin in 1897, landed but then collapsed; the ZMC-2 flew 752 flights between 1929 and scrapping in 1941; while the Slate ''City of Glendale'', was built in 1929 but never flew. History Early designs One of the earliest proposals for a flying machine based on rational principles was Francesco Lana de Terzi's design for a vacuum airship, c.1670. He had measured the pressure of air at sea level and based on this he proposed the first scientifically credible lif ...

Airship Industries
Airship Industries was a British manufacturers of modern non-rigid airships (blimps) active under that name from 1980 to 1990 and controlled for part of that time by Alan Bond. The first company, Aerospace Developments, was founded in 1970, and a successor, Hybrid Air Vehicles, remains active . Airship Industries itself was active between 1980 and 1990. In addition to the manufacture of non-rigid airships, several of the companies were involved in abortive proposals for many other non-rigid and rigid types. The historic airship facilities at Cardington, Bedfordshire (formerly the Royal Airship Works and RAF Cardington), were used as a base for the firm's test flying and an assembly site for some of its airships. Aerospace Developments, 1970–79 Beginnings and the Shell International Gas project Aerospace Developments (AD) was founded in 1970 by John Wood and Roger Munk (Jeffrey Roger Munk 1947–2010).
