I'm most likely speaking out of turn here, this isn't the first aircraft to be called fundamently unsafe by people. The aircraft either meets certification criteria or it doesn't.
If it does, then maybe that criteria needs to be revisited, or a look at the common human factors involved. I seem to remember the same witch hunt on about the little MU2, sorry not in the same league as the MD11. But from the little I understand it had a big improvement in its accident rate after a lot of retraining and understanding.
