I think Disney is rather unique. If you look at an FAA map, there are only a handful of TFRs. You will see temporary ones pop up for Air Force One or the Vice President. Stadiums will also get them on game day. It got slipped in with 9/11 legislation from what I've read/heard.
That is correct... I am not sure of any other for profit business aside from stadiums that get their own NFZ. Put into place after '9/11', originally it may have been a credible reason, but turned into a bonus for Disney since it was suppose to be temporary NFZ but they eventually made it permanent. I feel it had more to do with cooperating with Disney to prevent aircraft from flying over. Disney is very private about any type of filming on their properties. They even restrict the type of land based photographic equipment in the park, no tripods, etc. The TFR has both Disney parks in Cali & FLA listed as "National Defense Airspace".
Rumor has it that Walt requested the NFZ over MK because he didn't want any "visual intrusions" to effect a guest's experience at the park. Another rumor says Walt didn't want people flying over as a tourist attraction creating helicopter & small aircraft flights overhead. It could make sense as the park's popularlity grew, sightseeing increased. It is really interesting to see DL from the air, trying to pinpoint the well-known attractions. "Visual intrusions" could be a possibility too to not intrude on a guest's experience.
And yet another rumor is that the NFZ was place over both Disneyland and Walt Disney World the day before the Iraq war started last March. It was imposed by the FAA as a reaction to code Orange, not by Disney as I have been told by another source.
Interestingly enough, there is a private runway on the FLA Disney property built in 1970 that was used for a brief period of time. The runway is still there today but it is used for a maintenance parking & storage of miscellaneous items...
Shawnee Airlines and Executive Airlines both commenced service to Disney on 10/22/71 using Twin Otters. Shawnee initially offered nonstop service to Ft. Lauderdale, Orlando Herndon Airport, Tampa, and West Palm Beach while Executive operated nonstops to Orlando Herndon and Tampa. A third airline, VQ, operated by Volusia Aviation Service, used Beech Bonanzas and a Piper Cherokee on flights between Disney, Orlando Herndon and Daytona Beach.
A year or so ago Disney is asking for a provision in the NFZ to let them fly drones over the park for a light show instead of fireworks due to the high cost. Not sure what ever became of that.
In 1974 - 1982 there was an air themed concept for the San Diego park that would of included aerial rides but it never materialized though the land (200 acres near La Jolla) was purchased and all government approvals were obtained including ones needed for a private airport. The deep recession in 1982 made it near impossible to fund the $100 million park, but later on San Diego got Legoland instead.
Here's is the Victory Field image from Disney's America concept art...
The Victory Field area of Disney's America would have paid tribute to World War II era servicemen and military technology. It would seem that some of those blue sky concepts ultimately evolved into the Condor Flats section of Disney's California Adventure. Press material provided the following description of Victory Field:
"The flight of the Wright brothers opened a new chapter in American history, bringing with it thrilling exploits and military advancements. With the assistance of modern technology, guests at Victory Field may parachute from a plane or operate tanks and weapons in combat, and experience firsthand what America's soldiers have faced in defense of freedom."
So there ya have it... more information than you ever wanted and no clear answer.
