What amazes me, is that I either overread the info on previous flights/sleep patterns/time acclimate to local time or it is not in the report...
THIS is EXACTLY the fukc up one expects when you are out of your comfort zone fatigue wise. Of course, thats just my opinion, however...
The broken mic will certainly not have helped to create a, say, comfortable atmosphere.
And +TSRA is right, the amount of info can overwhelm one, especially in types without APU.
Together with the ever increasing BS "they" (e.g. Eurocontrol and local ATC provider) throw at one (CTOTs, TOBT etc.etc.), this is an accident waiting to happen (not saying it has anything to do with this one...)
