Civil tilt rotors
Ok call me a fat, unadventurous, unimaginative snob....
But I think that if I was the kind of high net worth individual they're aiming the 609 at, I'd really rather fly from heliport to airfield on a nice, spacious S76, AW139 or Bell 222 and then be decanted to my waiting Gulfstream than to duck and wriggle into the cramped confines of the 609, unless I was going to be sitting behind the stick.
And if the whole Vortex Ring issue has come quite so close to scuppering military tilt rotor ops, can we really believe that a civil tilt rotor will be accepted (even if it somehow gets certificated) by enough people to make it a goer?
Feel free to point out where I'm going wrong, please!
