I may be mis-reading the way you've written this sentence. My understanding is that the horozontal stabilizer and elevators on the -11 are the same (have the same area) as on the -10. With the additional length and weight of the fuselage and other structural components on the -11, the horozontal stab components are effectively smaller (percentage-wise) and less effective, thus the higher approach speeds of the -11. Is this incorrect? The "engine in the wing root" design of the Comet, while graceful and aerodynamic, certainly presented some containment issues with regard to catastophic engine failures.
