So we are expected to believe that Boeing never connected the dots between:
1. We design planes for US pilots
2. We sell planes abroad
3. Incidents abroad can ground an entire aircraft series
This makes them seem more incompetent, not less. It's not like they have no say in what's considered standardized training for the series.
From my understanding of the issue, Boeing just needs to stop the cost saving measures that led to needing software to stabilize an otherwise unstable plane.
The choice to make is how difficult you will allow features to be, and how many difficult features you will add.
The answer has to be at least moderately high to get the plane off the ground. If it's too high then you have a bunch of deaths.
It's okay to say Boeing went too far on the scale, but to say they never should have been on the scale is misguided. Intelligence of the operator has to cover for certain aspects of the design.
