Thank you for that. One of the more sensible and helpful posts on this thread.
With the benefit of hindsight it will be interesting to see if his crew felt his pre-flight behaviour offered a serious clue that things were far from normal or whether it was all within the bounds of 'he was having a bad day' - such as we all have from time to time
Apart from the tragedy of the man himself I suspect that the event overall may provide positive lessons for crews that will be taught in the future in the CRM context.
