The 9-11 hijackers forever ruined "flying cars" for everyone.
Why?
It would be reasonably practical for me to commute to work in my Lanciar 235 that I keep at a hangar house in the Arizona Mountains. I work less than 100 yards from the fence at Scottsdale Airport, 40 air minutes away.
My only problem is I can't persuade the airport to give me a key to get through the gate, and the nearest public gate is on the opposite side of the runway, 1.5 miles walking. I don't want to buy another car to leave over there, because I haven't committed to doing this every day.
But if my wife gets set up to telecommute, we'll sell the house down here and maybe I'll buy the extra car.
Now if this was Falcon Field instead of Scottsdale, they don't even have a fence. It's great, like a timewarp to 1960. I hope they never build one. It's a waste anyway, because a bad guy could cut a hole in the fence in the dark any time they wanted at almost any public airport in the country, and probably most Air Force Bases too (I used to work in a nuclear weapon area in the AF, so I know what security is, and what it isn't).
