The De Beers aircraft is Zeppelin NT-07. The New Technology Zeppelin, which had its maiden flight in 1997, has framework that weighs about a ton. The cabin, engines and other main airship components all connect to the rigid structure, which has triangular carbon fiber frames and three aluminum longerons.
The envelope of the NT airship, made of many layers of laminated fabric, holds helium gas.
Three propellers with a maximum swivel of 120 degrees aid the Zeppelin NT to take off and land vertically, like a helicopter.
