History
Military years
The airfield was originally constructed as a U.S. Army Air Forces facility and military operations began in 1942 as Orlando Army Air Field #2, an auxiliary airfield to Orlando Army Air Base, now known as Orlando Executive Airport. Orlando Army Air Field #2 was renamed Pinecastle Army Airfield in January 1943. At the end of World War II, Pinecastle was briefly used for unpowered glide tests of the Bell X-1 from B-29 aircraft before the program moved to Muroc Army Airfield in California– now Edwards AFB – for the world's first supersonic flight. With the establishment of an independent U.S. Air Force in 1947, the airfield was briefly placed in caretaker status, until being reactivated during the Korean War as a Strategic Air Command (SAC) facility for B-47 Stratojets and KC-97 Stratofreighters and renamed Pinecastle AFB.
In the 1950s, the base began hosting SAC's annual Bombing and Navigation Competition. A B-47 Stratojet crashed during the 1958 competition, killing Colonel Michael Norman Wright McCoy, commander of the 321st Bombardment Wing, which was the host wing for Pinecastle AFB. The following year the base was renamed for McCoy. The base later was home to the 306th Bombardment Wing operating the B-52 Stratofortress and the KC-135 Stratotanker. It was also used by EC-121 Warning Star early warning aircraft of the 966th Airborne Early Warning and Control Squadron, a tenant unit at McCoy assigned to the Aerospace Defense Command.
During the Cuban Missile Crisis in October 1962, McCoy AFB became a temporary forward operating base for more than 120 F-100 Super Sabre and F-105 Thunderchief fighter bombers and the primary base for U-2 reconnaissance aircraft flying over Cuba. One of these U-2s was shot down by Soviet-operated SA-2 Guideline surface-to-air missiles near Banes, Cuba. Its pilot, Major Rudolf Anderson Jr., USAF, was the crisis' only combat death. Following the crisis, McCoy AFB hosted a permanent U-2 operating detachment of the 100th Strategic Reconnaissance Wing until 1973.
McCoy AFB was identified for closure in early 1973 as part of a post-Vietnam reduction in force. The following year, McCoy's 306th Bombardment Wing was inactivated, its B-52D Stratofortress and KC-135A Stratotanker aircraft reassigned to other SAC units and most of the McCoy AFB facility turned over to the city of Orlando by the General Services Administration (GSA) in late 1974 and early and mid 1975. USAF responsibility for the airfield's air traffic control tower was turned over to the Federal Aviation Administration (FAA) and the airport established its own crash, fire and rescue department, initially utilizing equipment transferred by the GSA.
Civil-military years
In the early 1960s, when jet airline flights came to Orlando, the installation became a joint civil-military facility.
