This is a failure because Boeing cut corners through their design process because they prioritized the following over safety: 1) Bringing it into the market as soon as possible so they had an answer for the neo 2) Ensuring that it flew similar to other 737s so that airlines would pick them instead of the Airbus due to not requiring pilot training. The MCAS/AoA issue is the most easily manifested issue that led to 2 crashes. There’s almost certainly other issues that may also exist with this plane that we don’t know about yet because they’re slightly less likely than the MCAS issue. And it’s possible that some of those other issues may also lead to fatalities. The fundamental problem with the 737Max wasn’t the MCAS or the AOA sensors but the design process which greatly devalued safety. I’m not sure how possible it is to make up for that with after the fact testing.
