Cory Bird of Scaled Conposites built this plane. When he wasn't working on motherships, suborbital spacecraft and other things, he came up with his own GA airplane. Passionate people come up with beautiful ideas. His airplane is certainly beautiful. The only thing I don't like is the way the canopy opens, and that is a very minor gripe based on a particularly nitnoid safety concern. Gorgeous work!
