This is a "fifth risk" scenario, where the FAA misjudges other countries' aviation authorities as mere America bashers. The Feds also misjudge their own threat environment, gambling that the rate of hull losses due to MCAS problems is low enough to fly through.

The question, "What if we're wrong?" doesn't get asked. Instead, the FAA Administrator's boss tweets a complaint about aircraft being too complicated. No, the problem isn't overcomplication, it is failure to build, document, and train for the aircraft and pilots you have, not the ones you want.

The Trump FAA are clueless political hacks, not professional safety experts and airmen. They don't handle black swans well, and think of economic costs before human costs.
