Gary/Chicago International Airport has a new interim manager. The new private operator, AvPorts, introduced Duncan Henderson to the Airport Authority Board on Monday. Henderson, a commercial pilot, was most recently executive director of the Waukegan Port District in Waukegan, Illinois. The chief financial officer for AvPorts says Henderson will serve for the next few months until a permanent airport manager takes over. AvPorts is managing operations at Gary/Chicago International as part of a historic new public-private partnership with the city to develop the airport.
