This is nonsense, this is a repeat of correctness by construction vs correctness by test that we see in software. Since these planes are poorly constructed, due to failure in process controls, they must now rely on a correctness by test which is more expensive and less effective. I would argue that in such complex systems no amount of testing can ever make up for failures in controls.

Relying on the constant vigilance of pilots is a non-starter due to the limits of simply being human. Which is why risk is modeled using the Swiss cheese model. Pilots have off days and cannot be relied to catch everything, especially if the issue is previously unknown.

This isn’t the first 737 Max issue so why didn’t Boeing take the opportunity then to fix everything else wrong with the plane after the MCAS issues? Especially when they had the time during the pandemic to do so. How many new final issues should we expect? 3.. 4?

I’m not saying flying is going to be drastically more dangerous, just that it’s more dangerous than it could have been.
