Okay, maybe not a Zeppelin(TM), but still:
The first rigid airship to be built since the 1930s is about to commence trials in California: and the Pelican prototype also features a new technology, never yet flown, which could finally change things for lighter-than-air craft and see the leviathans of the skies make a serious comeback at last.
The 230ft-long, 18-ton demonstrator has been built for the US military by radical airship firm Aeros of California, helmed by Ukrainian LTA visionary Igor Pasternak. Aviation Week reports that it has now tested its ground manoeuvring equipment inside its hangar, and that next week the ship is set to actually lift off in a further sequence of tests for the Pentagon.
In particular, the US military wants to see if the Pelican can defeat the great bugbear of airships: the fact that they cannot usually offload cargo or passengers without taking on equivalent amounts of ballast. This is because, as weight is removed, the ship will become massively buoyant and will surge upwards uncontrollably.
