Thought you guys may get a kick out of this. Jim is quite a accomplished famous/infamous designer (opinions vary!) that I have done flight testing for on a few of his designs. Jim designed this "car/motorcycle" well over 20 years ago. For those of you who don't know who Jim is, he designed the BD- series of aircraft, the most famous of which was the BD-5, which many people would recognize as the "Budweiser" or "Coors" jet, and was flown through a hangar in one of the James Bond movies. No matter what anyone says about Jim, he has always been well ahead of his time as a designer and he continues shows the world what
can be done...
I would love to see someone to modernize the idea with more efficient engines and electronics.
