After Cargolifter filed for insolvency there is still the impressive hangar in Brandenburg which could house two CL-160: The world's largest self-supporting building, plenty of room for 14 B-747. It is about 1,200 feet (360 m) long, 700 feet (210 m) wide and 350 feet (107 m) tall.
According to "Der Spiegel", the hangar will likely be scrapped, because maintenance is extremely expensive.

For those unfamiliar with Cargolifter: The concept was to create a giant airship as a "flying crane" designed to carry out heavy load and point-to-point transportation while using almost no infrastructure.
CargoLifter AG wanted to be both - airship builder and logistics service provider.
It is a shame the company filed for insolvency; yet, I still have faith in the idea. Maybe we will see more competent and wealthy businessmen in the U.S. soon who copy the businessplan.
