Fatigue that is guaranteed by CDO's. Why would we ever do that?

Carl, it might be more accurate to say flight 5191 was caused due to lack of attention to detail which is normally associated with fatigue and circadian lows. It should be noted the solo tower controller was also said to be fatigued and did not provide a stop gap to the chain of events that ultimately cost 49 people their lives.
"In April 2007, the NTSB made four further recommendations, three measures to avoid fatigue affecting the performance of air traffic controllers."
