A great development.
However,
Boeings real problems are not in the aircraft, they are in the corporate managements failure to live up to their code of ethics. .
Sadly true, based on the evidence to date.
That is entirely the fault of the Board, isolated in an Chicago tower far from any of the operations. They rely on corporate presentations to make decisions, but those presentations may be at variance with reality.
Do note that this kind of separation of the leadership from the operations is also in effect in the defense sector, where most big firms are headquartered around Washington. There are obviously similar consequences there, but it is less visible.
