Eastern flight 401 shows the folly of trusting machines. On the surface. Maybe not so much of that. That can be argued, but perhaps the lack of tending to basics, what the aircraft is doing, what it is telling you should have been paramount. OK, I agree with more detailed observations on the L-1011 instrumentation and the fact that new systems led this aircraft to its fate.
Human, mechanical, and design failures led this craft to its fate. It all came together here.
