True, but you never see commercial planes flying over Disney, at all....I suspect WDW has some sort of agreement with the FAA to keep flight paths away from the complete complex. Knowing how Walt was for details, I wouldn't be surprised if that fact wasn't agreed upon before the first shovel went in the ground.
Walt had been dead for a couple of years before the first shovel went in the ground. And when he died in 1966 the Florida theme park was just a cut-and-paste copy of Disneyland circa 1965.
But when Walt was alive and running Disneyland in the 1950's and 60's he insisted on a heliport right at Disneyland. It was a stop on Los Angeles Airways route from 1956 to 1972. And they were giant Sikorsky's that thundered and roared and shook the china cabinets on Main Street USA when they went overhead several times per day. It wasn't subtle, and it didn't theme with any of the lands at all, but Walt thought it was cool so it stayed.
Disneyland service started in 1956, landing in the Disneyland parking lot. That's the TWA Rocket to the Moon in the background.
Giant Sikorsky copters thundered over Walt Disney's Magic Kingdom via scheduled service to LAX, Long Beach, and Newport Beach several times per day. Per Walt.
Here's Walt in the Disneyland parking lot welcoming some of the first LA Airways passengers to his park.
By the early 1960's the Disneyland Heliport moved across the street to the Disneyland Hotel. A flight to LAX was 7 bucks, about $55 in today's money.
If Walt had lived to see any shovels at work in Florida, much less see what the place is like now, he'd want to know why there aren't helicopters and small jets landing along Bay Lake. Just make sure the China Shop on Main Street USA knows the flight schedule so they can close up the display cases before the rattling starts.
