A very unfortunate side effect of this debacle is that Boeing have put themselves into play in world trade tensions. Whereas before the different FAAs all had mutual recognition agreements, at a time of Trump inspired trade wars Boeing has made themselves into the ball that will be kicked up and down the muddy pitch until it is bent out of all shape. And all to save a few hundred million dollars and undo decades of superb engineering. It's hard to think of a bigger self-inflicted injury. The entire 737 management team at B would resign out of honour if they were Japanese.
