And, in fact, a fighter plan has been successfully landed at Edwards/Dryden with no use of control surfaces. Even better, the same feat was achieved, several times, with an MD-11! It required some clever reprogramming of the fly-by-wire system to translate control inputs to engine thrust commands, but worked quite nicely, I understand. Manufacturers and airlines don't seem to be interested though. -- -Stephen H.
