Its not a Douglas invention and any self respecting Unicorn wouldn't be seen within a country mile of this thing...beside which, not sure it'd be able to get in thru' the car type doors !
Hmmmmm, clues ?
Its an American design, not mass produced, looks like it was designed by a redneck committee that weren't talking / drinking with each other, and it has a wheel at each corner !
It's not one of those concept flying cars, is it? Like the Moller Skycar, although it's not one of those. Whoever made the leading edge intake lip above the fan needs a good lesson in bogging, sanding and filling.
