So, basil, 'the flight was not perfect but that's the real world' eh? Are you saying then, that in your 'real world', lip service is paid to performance calculations and that questioning CRM standards is, for some reason, not acceptable? Commercial pressures encouraging flight crews to take short cuts to which airlines turn a blind eye can never be acceptable. Does that sort of thing go on in your airline? If so, please tell us for whom you fly so that we can choose a safer carrier?
The company culture which led to what must be now be well documented errors must seriously be in question; perhaps Concorde's fire would never have happened if the aircraft hadn't been put at risk before the take-off roll was even begun.
Accident inquiries seek the truth these days, they do not apportion blame. Some very searching questions have been posed on this thread - but there has also, regrettably, been considerable nonsense posted by others.
