Harry,
Well said in the comparison "what if it was EK and not Asiana". I think that recording of words here are very important about some issues so that it can never be said that the crew were not concerned should anything ever happen.
There are rules and there is reality, the rules of rest and fatigue DO NOT match with reality and alertness.
If it was not for the determination of the crews and their profesional attitudes to cope with what they are dealt with, there would be, without doubt, major problems. Sadly many are trapped in a system where the need to provide for the family and to not uproot them and cause chaos to go back home due to studies etc. Personally, I have never known how dire fatigue could be until I operated with EK, it's fatigue on a whole new level.
