The rocket as we know it for space flight is obsolete according to the rocket designers. Why do we still use them? However, the missile continues to be essentially a rocket and a weapon. We are interested in flight for human Cooperation. The rocket confirms the craft's fuel dependency on an external fuel supply. But, if there is a fuel for the initial take off, hydrogen is suggested with a fuel saving fuel cell to power large turbo jet fan engines. This would mean the craft can be designed as a regular winged craft for take off and re entry.
