After a duty like that, fatigue does not play a part. After a long duty, fatigue does not play a part, either. Red herring.

that is rubbish!
Anyone involved in avaition should know that you are talking about
tiredness - fatigue is different and often arises through cumulative duties and time zone messing. You are, however, possibly correct in what you say regarding fatigue on THAT duty alone, but there are many other issues that decide fatigue. None of us here know the work/rest pattern of the crew prior to the crash - or do
you?
