They were talking about these (larger versions) a few years ago as rescue vehicles for hiigh-rise buildings. The can touch right up against the building since the rotors are protected.

They would be nifty for shipboard operations, too. They will need a lot less flight deck for rotor clearence, and would eliminate the chance of some gristly accidents.

With "fly by wire" technologies and the gyros used by the Segway, I am surprised such a vehicle is already on the market.

And since this vehicle doesn't have exposed blades or rotors, a safety chute (or two) with a jettison device would be perfect for those pesky but rare incidents of engine failure.
