So why could Boeing not design it right in the first place? It is easy for people to just assume they made stupid mistakes, but that is very unlikely to me. I presume they made engineering decisions and tradeoffs based on issues we do not know. And if so, can they implement a system that does not push the risk elsewhere?
Do agree that the true next gen mid-size (whatever it is) is needed ASAP. Even if they fix this issue, the 737 kind of sucks.
Even more complicated, Boeing in their filings w/ the FAA reported that MCAS would be able to make a maximum adjustment of 0.6 degrees. However when they realized that would not be enough to compensate for the stall-risk, they adjusted MCAS to be able to make 2.5 degrees of adjustment. Except they neglected to mention that change to the FAA, so the final FAA analysis/approval was done using incorrect numbers.
