I never said Erebus was a crew stuff-up. It was however one of those accidents that held lessons for all of us. That is what I meant by a signature accident.
Tenerife told us, inter alia, that we needed to rigidly enforce SOP's and employ the, as then unknown, CRM.
Fort Worth was the first time microbursts and their effects really became known. That wasn't a crew stuff-up then either... although any crew doing what they did now would certainly have some explaining to do. (If they survived).
I take your point Kaptin that this SQ error was probably due to some form of distraction on the flight deck. That doesn't excuse them though. Managing the inevitable distractions that occur during a pre-flight is one of the other things we get paid for.
