Here's what I don't understand: the 737 MAX was introduced in 2017. In 2018, two of them dropped out of the sky, the grounded for a while, it turned out Boeing had lost its engineering culture and its priority for safety, and it became clear that the 737 MAX had some serious design problems that they had tried to fix in software. And according to this article, the 737 MAX is Boeing's best selling plane ever. Why? Why…
Well a lot of them didn't fall out of the sky and were used like millions of times, and the reason a few of them did was ostensibly fixed so now the chances of them falling out of the sky is even less than when most of them already weren't.
the need for MCAS in the first place is a major design flaw and results in additional failure modes that other aircraft do not have. the "fix" was to prioritize human inputs over MCAS, making these planes more vulnerable to human error. still worth avoiding IMHO.
