Hi Dc10tony and Tedski, Buzz here. I'll have to disagree with Tedski, since that AA DC-10 roll-over-and-die at ORD, the DC-10 have had a lock installed on the leading edge slat drive wheel and cable. Yes, there is a big wheel that pulls cables, thumped my head on it a few times. And i like Lockheed aircraft, we only had 6 of the L1011-500's to compare with the almost 60 DC-10's we were flying.
I'm not an expert at aerodynamics, but one thought: There's a mighty downwash of air coming off the wing, sometimes the horizontal tail has a lot of dihedral to get some of it out of the downwash as you get to higher angles of attack.
