Paul Moller (the aircar guy) has finally made at least one of his designs available for sale, the Volantor.
Ok, it's a tad goofy looking, and at 125k$ plus, it's bit out of, oh, damn near everyone's, price range, but still, it is for sale.
Personally, I'm waiting to see the first M400 flying around.
The amazing thing to me is that this guy has been working on this idea since the 60's, developing all sorts of technology in the interim to fund it (and contribute to it).
Dr. Moller, keep it up!
