The airport code MCO stands for the airport's former name, McCoy Air Force Base. It was named for Colonel Michael Norman Wright McCoy, USAF. In the early 1960s, with the creation of commercial jet airline service to the Orlando area, the installation became a civil-military facility. After the Vietnam War, McCoy AFB was to be closed. All Air Force flight operations ended in early 1975. The airport was known as Orlando-McCoy Jetport until being renamed as Orlando International Airport.
