people who know the Captain revealed that the Captain is procedural, and tends to let the F/O help in the decision making process, as in, not the tyro/ego type with huge loss of face issues...
PK-KAR, if that is the case then perhaps we may later find that the Captain was under some personal pressures from events in his private life. People are fallible, they make mistakes for all sorts of innocent reasons. I seem to recall the case recently of a RYR Captain who did something stupid having returned to work only a couple of days after a bereavement, because the uncaring company would not give him any more time off. (Of course the company later pleaded complete innocence blaming the Captain for returning to work too early!)
There might yet be a greater dimension to this accident.
