In case you've heard of X-plane, it's a simulator for PC or mac, where you can "design" your own planes, experimental or not. One guy, Bradley Gillis, desegned the VF-1 for x-plane, it works great! Thrust vectoring allows you to experience triple, quadruple kulbits, and the weight/power ratio allows to reach the end of earth's atmosphere quite easily.
