One wonders about the width of the wings- did they need to have so much span to provide the necessary lift?
One wonders about the shape of the aft fuselage - did it help by providing additional lift? Or was it all fuel tank?
One wonders about that extended vertical fin and movable rudder???
One wonders about all those reinforcing ribs on the outside of the tailboom...well, no, come to think of it one does not have to wonder about those...
And one wonders about that "reverse camber" extra horizontal stab - was it necessary to keep the nose up at such high speed? Couldn't the adjustable "regular" stab have been rigged to do that? Did the B-model even have a movable stab or did that come later with the D-model? Looking at the angle that the engines are mounted at, that thing sure must have humped along at a fairly nose-down attitude.
One wonders why they didn't try to clean up that draggy airframe even a little bit (other than the landing gear crosstube fairings that Bell puts on and take off seemingly randomly).
And finally, one wonders how that puppy would do with a pair of Williams FJ22 engines mounted out there! Nevermind having a King Air that hovers, we'd have a Huey that goes like a Citation! That that, V-22!
