Boeing are to build for Skyhook the JHL-40 (Jess Heavy Lifter) termed a neutrally buoyant rotorcraft which must be the politically correct term for an airship with big engines. The JHL-40 does not carry a lot of gas though, just enough for countering the craft's weight. The JHL-40 is a helium filled airship anyway and will be able to lift 40 tons and transport it 200 miles.
