not be offended at me asker( in which at least two errors), but the longer we write illiterate, the longer it will have to wait for the next industrial revolution.Literacy disciplined mind and prepares it for the challenges.
If the answer seriously, that already have machines that are able to travel on public roads, as well as the fly( "folding" airplanes and helicopters).So technically it is possible.But!Not ready for the public consciousness and the state apparatus.Many respectable country strictly regulates flights over its territory.Someone shpiono-, someone terroroboyazn. ..
Today's state of the art allows you to make quite small helicopters and costs about the same as cars.But marketing courses do not allow to produce aircraft at a price, as the flight is considered that the lot is "privileged".
And finally why I spoke of the industrial revolution, when everything is so real.Everything, but not all. .. for the mass transition to flight( in replacement of driving on the road), the engine needs a new level.Specifically, the new Energy level of the engine.Once invented compact and vysokoёmkostny and Fast-battery, so comes the era of other vehicles, including( possibly) and air.Alas, this is not.And if there is( some say futurologists), then securely kept secret grand monopolies - fuel producers.
So we take off when:
1) open borders;
2) get a new way to stock( receipt) of energy;
3) and the most difficult - to overcome the resistance of the global monopolies.
