I am afraid the PF's behaviour fits RR NDBs fourth category.
I think we all need to be cautious in evaluating this crew's personal characteristics.
We have the advantage on them of knowing how their efforts turned out.
They were humans like us and did not intend to have their efforts turn out badly. We make mistakes, we have training issues, and poor performance issues. The same weaknesses applied to them. We are only in the early phases of learning what they were up against. Hopefully BEA will be able to put this whole puzzle together.
If we are to be critical, let us be critical of their performance, not their persons.
There is still a lot we do not know.
