He now adopted the "admit the problem and fix it" attitude because he was "caught", before that was business as usual for Boeing. It was/is more a "don't ask, don't tell", dump the risk on other separate entities/companies and cross your fingers because we need to get those planes out of the assembly line as fast and cheaply as possible no matter what.
Boeing is and has been under pressure, but it's their own fault. They have been fucking around for DECADES now and when there were "difficulties" they always called the US government to "facilitate" sales or their buddies inside the regulatory bodies to put the green check on their garbage.
Nothing about this is news, it has been known for years and years.
Unfortunately Boeing always has a sweet defense contract waiting to compensate any "rough year", so they keep fucking around..
