Eureka at Moffett Field after Flight.
The Zeppelin NT ("Neue Technologie", German for new technology) is a class of airships being manufactured since the 1990s by the German company Zeppelin Luftschifftechnik GmbH (ZLT) in Friedrichshafen. The initial model is the NT07. The company can be considered the successor of the companies founded by Ferdinand von Zeppelin which constructed and operated the very successful Zeppelin airships in the first third of the 20th century. There are, however, a number of notable differences between the Zeppelin NT and the airships of those days, as well as between the Zeppelin NT and usual non-rigid airships known as blimps. The Zeppelin NT is classified as a semi-rigid airship.
The Zeppelin NT airships constructed so far are 75 m long, with a volume of 8,225 m³. They are thus considerably smaller than the old Zeppelins, which reached a maximum volume of 200,000 m³. Furthermore, they are inflated exclusively with the non-flammable noble gas helium.
