That’s a great explanation, even if it is oversimplifying.
We don’t build planes with training wheels anymore because the performance cost was too high. Planes are still the safest way to travel even without the training wheels.
I don’t think 737 MAX 8 pushes the envelope too far. I think they screwed up on re-training the disengage, and they may have screwed up on redundancy by only using a single AoA sensor, but I also am guessing the latest crash has absolutely nothing to do with trim.
There are two alpha vanes on 737s, including the MAX 8, that measure angle of attack. Also we don't know the exact source of the error (in the Lion Air case; in the Egyptian Airlines case we don't know at all). The vane itself could be the source or some other part of the system.
