Dade-Collier Training and Transition Airport, formerly the Everglades Jetport, (IATA: TNT, ICAO: KTNT, FAA LID: TNT) is a public airport located within the Florida Everglades, 36 miles (58 km) west of the central business district of Miami, in Collier County, Florida, United States.

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.

It was originally heavily used by Pan Am and Eastern Airlines as a training airport, as the long runway at Dade-Collier could accommodate aircraft as large as Boeing 747s, and was equipped with a relatively new instrument landing system, which allowed pilots to train for landing with low cloud ceilings and/or poor visibility.

The isolation of the airport meant that it could be used for training flights 24/7 all days of the year without interfering with the traffic at Miami International.

[4] Dade-Collier Training and Transition Airport covers an area of 24,960 acres (39.0 sq mi; 101.0 km2), which contains one asphalt paved runway (9/27) measuring 10,499 × 150 ft (3,200 × 46 m).
