The Airlander may be the world’s longest and largest aircraft, but it’s the craft’s unique shape that makes it revolutionary: It provides 40 percent of the vessel’s aerodynamic lift (the rest comes from helium)—enough to keep 10 tons of cargo and a full crew aloft for five days. With its long airborne time and its ability to land on any flat surface, the blimp-zeppelin hybrid is the perfect vehicle for humanitarian, border patrol, transport, and search-and-rescue missions.
