No doubts about the experience of the pilots. But in a cargo aircraft it is very difficult to check the work of the loadmaster and loading staff. What is the guaranty about their skill and knowledge? ( Zim registration ) Zero! A mistake in loading is so easy, most of these guys think it`s just a truck! So putting the aft cargo fwd and vice-versa is not a problem. Or just the cargo of another flight! I`ve seen it, and not only in Africa; in Europe, yes!
Maybe in this case you can just add lousy uncontrolled maintenance, unrespected duty times,
and you have an accident!
Not at all an MD-11 problem in this case.
