I was flicking through the latest cabin crew CHIRP feedback the other day and found this. Im flight deck and to be honest I’m shocked at the last paragraph of the feed back.
"Turning to the reporter's comment that they would be too tired should an emergency situation arise. Studies have shown that should a tired person be involved in an emergency situation the surge of adrenalin will normally be sufficient for them to act accordingly."
I am not sure why you are shocked ? I appreciate that whatever the merits of the arguement this answer does not address the politics of the cause. However it is biologically correct.
