Why did you stick that little fan on your helicopter? Did the complexities of flying a rotor edgewise overwhelm you? Did you say to yourself "why compound this problem with two rotors. Let's try and get away with one."? I've heard that you were later astonished by the technological sophistication of Flettner's intermeshing helicopter, when you saw his film at the AHS meeting. Please say that you didn't contribute to Charley K. leaving the company, and then having to develop his intermeshing helicopter idea with insufficient funds.
You must agree that virtually every living creature, with mobility, has laterally symmetry. You must agree that most of mankind's progress is founded in nature. You must agree that this lateral symmetry is universally applied in man's vehicles. Do you not agree that optimal VTOL can only be achieved by adhering to nature's Darwinian logic?
Why oh why did you stick us with that dinky little fan. Sixty years is long enough. Let vertical flight resume its rightful place in air transportation.
