I have the exact opposite impression. I don't know why the board hasn't fired him yet. He was brought in to change the company culture. It's been 4 years and this happen. 4 years is a long time, and this failure shows that he failed at what he was hired for (no, making money is not his main job.)

Of course he is going to say whatever is needed to save his job, but in my eyes Boeing should move on and choose someone else. Time is running out.
