The 911th Airlift Wing performs fire drills to test the response time of both the 911th Airlift Wing and the Allegheny County Airport Authority Fire Department at the Pittsburgh International Airport Air Reserve Station, Pennsylvania, Dec. 10, 2020. The 911th Airlift Wing does not have a stand-alone fire department on the installation and therefore relies on the assistance of the neighboring Allegheny County Airport Authority Fire Department.
