Docjell,
I thank you for your brutally honest assessment.
Arrogance is each our own nemesis and mortal enemy, usually it comes from overconfidence, a human frailty. There but for the grace of God go any of us.
Loved by many, popular to so many, a great contributor and willing to be a friend to any genuine person, our mate was human and frail to the end like all of us.
I have to agree totally with your closing line "This awful event, that has traumatised many, should remind all of us that experience, flying hours, and having the 'right stuff' is not necessarily going to guarantee our survival."
