411A Fatigue is cumulative and comes about over a long period of night flights ,early starts etc etc and all I said was I took this into account when loading fuel to any destination where the forecast gave a possibilty that on arrival a hold or diversion was likely. I thus avoided the " must land at any price" which is a very unpleasant situation to find oneself in.
I always found it difficult to get good rest between night flights whether in a Hotel or at Home but 411A we all know you are super human. This does not in any way excuse this accident or make it acceptable in any sense for that reason alone.
Over the years when taking over an aircraft I have shuddered at times to see how little fuel some people arrive with.
