Tired Crew.
The NTSB say that 70% of all transport accidents are fatigue related.
Given the time of this incident it is understandable why people are asking for details of the duty invovled.
I think it is where I would start to try & unravel the problem. We all make mistakes & make them more often when tired. The circadian issue of night flying cannot be disgarded either.
Has anybody have either info on this crew's duties both prior to or on the night in question? Other TNT crews perhaps?
