While the sleek bullet-like form of the above rocketship is impressive, questions arise about its space-worthiness. The craft appears to be a hybrid mix of jet aircraft and space rocketship designs. For example, wings and a vertical stabilizer are included for atmospheric flight, but air scoops which characterize air breathing jet engines are absent. Instead, three rear rocket engines propel the craft.
Though the engines may be gimbled for thrust vectoring, no orientation control thrusters are apparent. The ship is unsteerable in space or in the atmosphere. The wings and tail have no control surfaces for pitch, roll, or yaw. Yaw might be accomplished by independent throttling of the three engines, but without thrusters, roll and pitch would be impossible.
Additionally, the pipes which run from the fuselage to the outboard engines' thrust chambers are puzzlling. In order for a rocket engine to provide thrust, an igniting of both fuel and oxidizer must occur. There should be a second pipe leading to each of the thrust chambers. Perhaps, the second propellant simply flows into each chamber via a pipe concentric with the engine nozzles.
