A very interesting idea which I had never heard of. Obviously the aircraft must have a vertical landing capability but airframe damage should be minimal and removal time reduced to allow continued operation of the flight deck. I suppose the main risk is aligning the aircraft accurately given that both vessel and aircraft are moving independently of each other. Could be fun in rougher seas and/or blustery wind over the deck and would not be practical with the aircraft weight at higher levels or armed.
