Flying a short-notice trans-Atlantic sortie from the west coast to eastern Italy in a Navy tactical jet to support Operation Allied Force (Kosovo conflict). Upon landing, many crews were scheduled to fly the next night to support combat operations. Circadian fatigue ensued and we were all extremely tired and waking function was dangerously limited. Luckily no one was hurt and the AAA and Surface to Air Missiles kept everyone awake thru most of the night. Got me thinking about the commercial crews who did that every day and how dangerous circadian desynchronosis can be. The FAA doesn't have any regulation nor any hard data to support circadian fatigue mitigation techniques. I am interested in hearing from folks who have dealt with this type of fatigue and would like to describe their experiences with circadian fatigue in a survey at the link below:
