Read all the posts; others have touched on all the bases; people have been trying to do it for at least 75 years now; and it never has worked. O.K. here we are, 2011, new materials, new technology all over the place; from a purely engineering standpoint, I suppose almost anything "is possible", however unlikely; but ONE thing that has NEVER changed, and in fact, is getting worse by the day.............people ! What do you see on the interstates, the autobahns, the "super roads" ? more courteous drivers ? more "safety minded drivers" ? If you answer yes to either question, please tell me what planet you are on ! The human race has become a "rat race" ! People can't stand other people any more; and there are more and more people who can't stand each other every single day ! We hear a lot any more about the great "population explosion"..........................having enough "flying cars", "PAV's" ( personal aerial vehicles ) buzzzing about might just be the best, quickest "solution" to the "population explosion" !
P.S. If you think I'm kidding about people...............just go "down" on the "Non-Aviation Forum" for a few hours, and you will quickly realize I am right !
