Motor Skills: Getting Off to a Good Start 
A motor skill is a learned sequence of movements that combine to produce a smooth, efficient action. This month's CALLBACK looks into another type of motor skill– the skill required to produce a smooth, efficient (and safe) aircraft engine start. 
Two of the following ASRS reports examine engine start anomalies on commercial jets. Three additional reports highlight the dangers inherent in hand-propping light aircraft. All of the incidents provide compelling lessons for anyone who wants to get off to a good start. ______________________________________________________________
