 During the Phase 2 and Phase 3 efforts, the FAST team had the opportunity to train different groups of AF personnel on the use of FAST to solve fatigue problems they were having with sustained operations, overseas deployment, and night training operations.The training was accomplished with numerous groups in part through several of the USAF School of Aerospace Medicine's (USAFSAM) educational functions (2002–2007) and in part through the AFRL Aviation Fatigue Countermeasures Workshop taught approximately tri-annually by Drs.John A. Caldwell, J. Lynn Caldwell, and James C. Miller.
