I wanted to simplify the propulsion systems so I could go about designing some prototypes. I've even heard that there's no such thing as gravity, but instead of trying to figure out what that means, I've decided to go ahead and start designing cars that can fly, and of course the craft had to avoid the atmospheric friction of normal travel, so time was just sitting there, waiting to be folded with a little kink, right in front of the grill. And a force field too, for the rain, bugs and birds that might exist in that future that the craft is about to be in. Also, the craft is it's own 3D printer, so if the glass gets dirty, just print a new one anytime. I really am planning to draw a series of flying machines, just for the art of it. We'll see how many I do...
