I don't know about the supersonic transport stuff but Concorde served MIA
three times a week for about 6 years and we never had a noise complaint, unlike other urban areas of the US that raised holy hell about it coming once in a while on charter flights. TNT was built as a reliever airport in the late 60's for training purposes but the county had intentions of expanding it so it could ultimately serve as a complete replacement airport for MIA
. However, the environmentalists raised holy hell as they should have, and the federal government told the county to forget it and find another site. The county wasted numerous years picking other sites in what was then rural areas only to get shot down time and time again. They should have land-banked all the land west of MIA
out to the Palmetto Expressway because there were only a few buildings out there in the early 70's and it could have been bought cheaply. They did manage to extend 9R
-27L (now 9-27) to 13,002 feet in the early 80's but they had to reroute a major roadway and railroad tracks to do it.
TNT was heavily used in the 70's and 80's by Eastern, National, Braniff, Pan Am and others for pilot training. However, the cost of jet fuel and development of flight simulators caused a significant decrease in training flights.
About 90% of the airport's land actually lies in Collier County but Miami-Dade owns and operates the airport. All of the employees live in Collier County. It used to have it's own auxiliary airport manager until the mid-70's when it was put under the manager of Homestead General who had to drive out there once or twice a week. Sometime in the 90's it was put under the Kendall-Tamiami manager's responsibility since TMB
I've heard tales from guys who worked out there in the 70's about going flying on some of the 727's doing touch and goes and full stop landings there. The flight crews would radio them sometimes and ask if they wanted to go up and sometimes they did. The aircraft would stop on the taxiway, drop the rear stairs and the TNT employee would clamber up the stairs, the flight engineer would open the rear door, and they would do a few touch and goes and then drop the employee off. One of the fringes for working in the middle of the 'Glades?
There was an Eastern DC9 that impacted the ground near the airport while pilot training but I can't remember the details except that the aircraft was written off.
The county makes revenue from training flight permits, commercial shoots, and charges assessed to swamp buggy owners who keep their buggies stored on airport property. There is allegedly some sort of agreement that they will provide assistance in the event of a disaster like Eastern L1011's crash.
