Just to clarify a small point on the DC10 tragedy at Chicago, the actual thing that made the plane roll over was that the damaged hydraulics caused the leading edge slats on the left side retract, which raised the stall speed of that wing (but not on the right, where the slats stayed in position). Somehow the "out-of-configuration" warning was also knocked out, so the the crew had no immediate knowledge of the situation outside. AA's engine-out climb procedure called for the reduction of speed to V2 + 5 (I think), to allow for the best possible climb with reduced power. V2 + 5 happened to be lower than the stall speed of a wing without slats, so as the aircraft climbed, the speed fell until a stalled left wing was inevitable and the plane rolled suddenly right over and crashed inverted just outside the perimeter.
