The Danbury Fire Department has conducted their annual Aircraft Rescue Firefighting training at Danbury Municipal Airport.  The Police Department and Danbury Hospital EMS also took part in yesterday's event.  The weather forced them to change their plans for a full scale drill, but they still did training exercises.  Participants learned how to tug planes out of a hangar, where power system shut offs are in different types of planes, how to open hangar doors, and how to communicate with the Air Traffic Control Tower.
