Igor Pasternak is in the early stages of developing a prototype of The Flying Luxury Hotel:
Even though the Aeroscraft dwarfs the largest commercial airliners, it requires less net space on the ground than any plane because it doesn’t need a runway. The airship takes off and lands like a helicopter: straight up and down.
But it’s not a blimp:
Unlike its dirigible ancestors, the Aeroscraft is not lighter than air. Its 14 million cubic feet of helium hoist only two thirds of the craft’s weight. The rigid and surprisingly aerodynamic body — driven by huge rearward propellers — generates enough additional lift to keep the behemoth and its 400-ton payload aloft while cruising. During takeoff and landing, six turbofan jet engines push the ship up or ease its descent.
