I don’t agree. It’s not about being a better engineer than those at Boeing etc. (you might be right about that but it’s totally tangential).
It’s about being open and transparent about potential risks, being transparent about your mistakes and not outright illegally concealing them and cheating.
The Boeing problem is management and easy to do better than. Penny-pinch less on safety and inspections and leave everything else alone.
I've never seen someone say they could do better than air traffic controllers themselves. If this is about paying more and hiring more people... that's also something the average person is capable of handling.
Every one of them is wrong.
