"As has been stated several times previously in this long thread, the MD10 is a back variant of the MD11, and shares a type rating.
The DC10 is a different type rating and truly a different animal. "
It shares the type rating, this is the problem. Stick and rudder the MD-10 is no different than the DC-10. "Back Variant"??? Man they take a DC-10, cut a hole in the bell and drop the E-rack. Rewire most of the aircraft and slap a bunch of shiny knobs and screens in the cockpit then call it a MD-10. Are you under the impression that the MD-10 was produced new?
