Hundredpercent, I agree with you that more training and knowledge is required about startle factor. I think you're being a bit harsh on those who identify errors the Captain made though. If someone believes that the Captain made an error of judgement/leadership/ communication ( whatever) and they thInk there is a lesson in it for themselves and others, suddenly they're macho and an armchair expert/ flying god?
We have to be able to say what we think if we want to use a site like this for learning and it is inevitable that others will disagree.
