Ah yes, I heard about this one night on Coast to Coast AM. Of course they are possible. Practical? What
is practical? Would you (referring to all readers) deem any piece of technology practical? I think we could do just fine without all of it. But aside from that, flying cars have a positive side and a negative side; just like everything else. I do not see anything in the way of the production and distribution of the proposed vehicle. Like any technology, it will be a hit or a flop. I await the release!
Here is the website for a company that is developing the flying contraption. This has actually already been produced, and there are pics on this site of the vehicles. I must say the design is catchy!
