Relax AirRabbit, you're never going to get through to those "holier than thou" who live in a more perfect world than ours. Just know that there are those of us who do get what you are saying--that deicing procedures & culture at that time & place were much less precise than now, there was no stated holdover time, & the cockpit crew knew that if they went back for another deice that they would encounter the same or worse delay for takeoff. We understand your very plausible theory that the airplane was thoroughly ICED by faulty deicing procedures which made it unflyable due to a sudden uncontrollable pitch-up at the point of rotation. We also understand that many of the contributing facts you mention were not included or were glossed over in the NTSB report.
Thank you for your very knowledgeable input.
