(Undated)  --  The Minnesota Air National Guard is flying disaster response missions in earthquake-torn Haiti.  The 1-33rd Airlift Wing launched two C-130 "Hercules" cargo planes from Minneapolis-St.Paul last Friday.  Captain John Hobot  says the 53 airmen were heading to Puerto Rico, but the crews were placed on alert for Haitian earthquake relief operations when they arrived.  Hobot says they are hauling much-needed water, equipment and other critical supplies into Port au Prince and the Dominican Republic.  One of their first missions was delivering a generator that is being used to power a local hospital.
