Looks like the Germans got the same ideal. The German company Cargo Lifter. Is making one that can lift 160 tons.The CargoLifter CL 160 will be able
to move payloads that are too large even for the military's biggest heavy-cargo transport plane, the C5
To house this gigantic blimp, CargoLifter has designed one of the largest, self-supporting hangars in the world. The enormous hangar, under
construction in Brand, Germany, will be 1,181.10 feet (360 meters) long, 688.97 feet (210 meters) wide, 351.04 feet (107 meters) high and will cover
889.57 acres. To understand the enormity of this hangar, imagine a structure that could completely enclose the Louisiana Superdome, an arena that
holds 125 million cubic feet (about 3.53 million cubic meters). The CargoLifter hangar, which will hold 194 million cubic feet (5.5 million cubic
meters), should be finished by the end of the year.
They already started to build this hangar and have a pic in the link of it huge
