Mad, I've heard the argument many times, but the facts remain:
1. The stab airfoil is indeed inverted on many planes. If the stab is slotted, the slot is inverted as well.
2. Aft CG is desirable, and Fwd CG undesirable, for fuel burn at a given weight/FL/SAT. Look it up.
3. If the stab fails (or even half of it), which way does the aircraft pitch? The answer is in a few accident reports. Look it up. (Hint: Lusaka, 707 freighter, 1977)
Until these are rebutted I cannot accept the "lifting tail" in principle.
