Would it be out of place to expect that the airlines would have a "sleep room" set aside - maybe a room off of the crew room where pilots could get a quality nap? I've seen this type of operation in the military before. When I was in Kuwait back in 2003 during the summer time - it was nearly impossible to get a good day's rest in the unairconditioned general purpose tents with temperatures reaching over 100 degrees. Eventually they set up an air conditioned crew rest tent.
I agree that flying fatigued is a safety hazard - but not every mishap can be pinned on fatigue either. I'm glad they (NTSB) are looking at it but from reading the transcript they seemed alert (meaning not sleepy) but they had a breakdown in basic airwork.
