Do you have the ability to tell if a street is safe to cross?

Most of the time, yes.

Sometimes, you can't tell for sure, but you cross anyways.

Sometimes, you are dead wrong about your judgement. Shit happens. Nobody expects 100% certainty.

The problem here may be that Boeing may be falling to meet the expectation of 99.????% certainty, and regressing down to 99.????% certainty, due to a broken corporate culture.
