Batman's spacecraft lacks reaction control thrusters. Without them, pitch, roll, and yaw of the vehicle would be impossible. The main engine might be gimbled to direct its thrust to perform pitch and yaw maneuvers, but roll control would not be possible.

Another questionable aspect of the vehicle's design is the absence of some kind of horizontal lifting surface (a wing) to keep the craft aloft during atmospheric flight. The heliocopter type design includes a vertical stabilizer (tail) for yaw stability but no wing. A Heliocopter's rotor provides both lifting capability and translational power.
