Orlando International Airport
Facts on MCO
MCO's airport code doesn't stand for 'Orlando' at all -- it's a holdover from McCoy Air Force Base, a Strategic Air Command installation named in 1958 for Colonel Michael Norman Wright McCoy, who had died in a B-47 bomber crash the previous year. When the base transitioned to civilian use and became Orlando International Airport in 1976, the IATA code MCO stuck.
