I spent almost 21 years in Boeing Experimental Flight Test.
I helped certify most modern Boeing aircraft up to the 737 NG. I left Boeing before they did the MAX.
I had to certify my designs to the FAA.
I understand the process.
The MAX people failed miserably, not because they are bad engineers, but because “Share value” became more important than building the best aircraft in the world.
I left Boeing because of that change in focus of the Boeing product. I built the best aircraft in the world, the profits will roll in. I really didn’t care about making shareholders richer(although I was a shareholder).
Want to fix Boeing? Move Corporate back to Seattle.
Where I could walk across the street and make a complaint directly to the company president, if I thought something was wrong.
