The supply chain is long but it's supposed to have exceptionally detailed documentation. Follow that document trail and start prosecuting people when those documents start turning sour, because not documenting the work properly is a crime in itself.

This won't be sufficient to fix Boeing, but it would be a start.

Change the law so that design flaws arising from a culture/system that deprioritizes safety are considered criminally negligent for upper management (at least for safety critical domains like aircraft or cars).

Then you just have to prove that they intentionally deprioritized safety/engineering in their systems and culture.

> When people say I changed the culture of Boeing, that was the intent, so that it’s run like a business rather than a great engineering firm.

Yeah, hard to prove.
