Pitch up, pitch up.
Looks like MCAS can be a liability, as already speculated. It is a bit late to attempt to “enhance understanding” of how the system works. Boeing prides itself on giving pilots control, but seems to have designed something which denies them authority. Yes, it depends on a chain of mishaps and misunderstandings, but that is why systems ought to be designed with safety in depth, and not at the mercy of a single indicator, which may be fallible.
