life of a dispatcher

This is a video that was prepared by Delta Airlines about their Dispatchers which they call "Flight Superintendents".  It does a great job of explaining the functions and daily duties of a dispatcher and how they impact the overall operation of an airline.  It also explains the qualifications needed to be a dispatcher and the expectations you should have as a new dispatcher entering into the workforce.
