Not only that, PJ and loma, but it is somewat fanciful of BoeingMEL to think that sitting for X number of years in a commercial airplane cockpit confers on him the expertise to judge the quality of an accident investigation.
He might have that ability, of course, but if so then by virtue of his intellect and personal capabilities, not simply his profession. And given the style of his intervention I incline to doubt it.
