during 1943. From the beginning of 1944 flight training steadily diminished. The Air Force inactivated the base on 15 December 1945. Following the war, Cochran was utilized for various purposes. Smart Field remained as Macon's municipal airport until 1947. After a tornado swept Smart Field, the airlines moved their operations to Cochran where they remain to this day. The passenger terminal was built in 1959 and extensively renovated in 2003. The two Army built hangars still exist along with a few old warehouses. The Air Force at one time had a presence at the airport, hosting the 202d Engineering Installation Squadron, a non-flying engineering unit of the Georgia Air National Guard. However, this unit was relocated to nearby Robins AFB at the end of Fiscal Year 2011 pursuant to BRAC action. In June 2019, Brazilian regional jet manufacturer Embraer announced it would open a repair and maintenance facility for its ERJ and E-Jet commercial aircraft at the airport, in a hangar previously occupied by HAECO. Middle Georgia Regional Airport has also previously been known as Lewis B. Wilson Municipal Airport (named for the mayor of Macon between 1948 and 1953), Macon Municipal Airport, and Cochran Field. History of commercial service Commercial airlines historically serving the airport included Delta Air Lines and Eastern Airlines, both beginning in the 1940s using Douglas DC-3 aircraft. Both carriers later upgraded with Convair 440 aircraft and during the 1970s decade both carriers operated McDonnell Douglas DC-9 jets from Macon on flights to Atlanta. Eastern ended their service in 1979 and Delta transferred their service to Atlantic Southeast Airlines operating as Delta Connection in the mid 1980s. Eastern Express operated by Metro Airlines on behalf of Eastern Airlines brought back a return of Eastern service in late 1986. Both carriers provided service to Atlanta using a variety of commuter prop aircraft. In 1988 Piedmont Commuter operated by CCAir began service to Charlotte using Jetstream 31 prop aircraft. In 1989 Piedmont Airlines was merged into USAir at which time Piedmont Commuter became USAir Express. Eastern Airlines went out of business in early 1991 discontinuing its Eastern Express service while USAir Express discontinued service at nearly the same time. Delta Connection, operated by ASA, continued service until 2008 at which time GeorgiaSkies began serving Macon with flights to Atlanta under an Essential Air Service contract. GeorgiaSkies flew single engine Cessna 208 Caravan aircraft. In 2013 Silver Airways took
