CargoLifter [1] tried to bring Zeppelins back in the late nineties. They started building a gigantic manufacturing building but ran out of money before they even started to build a Zeppelin. The hangar was later turned into an aqua park but ran into troubles because the heating expenses were too high. Not surprising given the hangar was designed to be open at both ends.
Seemingly the Airliner 10 is now starting production (but as always happens with this type of stuff better wait until they have actually manufactured a few, 2020 is near enough):
My father actually bought quite a bit of "Cargolifter AG" stocks. Obviously they are worthless now.
The guy that founded CargoLifter (Carl-Heinrich von Gablenz) is still at it and his "new" company "CL CargoLifter GmbH & Co. KGaA" actually manufacture balloon cranes much smaller than the original CargoLifter design.
