History
Begun in 1968 as the Everglades Jetport (also known as Big Cypress Jetport), the airport was planned to be the largest airport in the world, covering 39 square miles with six runways, and connected to both central Miami and the Gulf of Mexico by an expressway and monorail line. The airport would have been five times the size of JFK Airport in New York. At the time, the Boeing 2707 was under development and it was anticipated that supersonic aircraft would dominate long-haul air transportation. South Florida was viewed as an ideal location for an intercontinental SST hub due to the limitation that such aircraft would have to fly over water. Because of environmental concerns and the cancellation of the 2707 program, construction was halted in 1970 after the completion of just one 10,500' runway.
The unfinished airport was maintained primarily for the purpose of training airline pilots, particularly for Pan American World Airways and Eastern Airlines which were based at nearby Miami International Airport. The long runway at Dade-Collier could accommodate aircraft as large as Boeing 747s, and was equipped with a state-of-the-art instrument landing system. The isolation of the airport meant that it could be used for training flights at all hours of the day and night. In more recent years, the advent of flight simulators has made such training flights less economical, and the airport is now used much less frequently, although it remains open to general aviation.

Facilities and aircraft
Dade-Collier Training and Transition Airport covers an area of 24,960 acres (10,100 ha), which contains one asphalt paved runway (9/27) measuring 10,499 × 150 ft (3,200 × 46 m).

Other uses
High-speed automobile events have been held here because the runway is two miles long. This allows exotic cars to break the 200 miles per hour (320 km/h) barrier, a pinnacle for street vehicles. Such events were held in 2009, 2010 and 2011.
Oil exploration on the site was considered in 2009, but not pursued due to resistance from conservation groups.
The Carlos Gimenez administration proposed holding a regular "Miami International Air Show" at Dade-Collier, similar in concept to the Paris Air Show. Homestead Air Reserve Base had previously been considered, but the idea had been rejected by the US military.
