Re: This is truely impressive

Fair points; what defines a successful space launch system will likely be the cost of pound (or kilo, or Approved Register Unit of Measurement) to orbit, however, the two technologies may co-exist: the Space-X approach may prove to be the commercial winner for routine satellite launches, but Reaction Engines offers potential long-distance sub-orbital (very fast) passenger/cargo travel.
