Varies by engineer. But what managers see is generally neither the
trees nor the forest. They're not even on the same continent. They're
sitting there reading a description of the forest provided by some
engineer.

Neither do I (and I don't need to ask an engineer). Getting a failure
doesn't mean that making the attempt was wrong. It may just mean that
the odds crapped on you that day. Now if you go back and do a root
cause analysis on the failure and find that the fault was one you
hadn't considered or it was one that you grossly misestimated the odds
of occurrence on then you arrive at "the decision to fly MAY have been
wrong".

Real engineers aren't the 'black and white' people that most seem to
think they are.
