As much of a fan of "space" science fiction that I am, the pragmatist in me must wonder if space planes will ever become practical until some new, relatively compact and light-weight, thrust generating energy source is invented. Also, the *incredible* re-enrty speeds and friction will have to some- how be ameliorated. (We're all impressed when the SR-71 travels at Mach 3 at 26,000 meters, and it's titanium body expands so much to seal the fuel tanks, but Columbia was traveling at Mach 17 and the nose of the craft was so hot that it turned the atmosphere into plasma!) And it goes w/o saying that artificial gravity (that can be powered by the same enery source that propells the ship) will have to be invented so that man's skeletal system won't fall apart during prolonged space travel. (Also, imagine how huch easier it would make eating, sleeping, shaving, deficating, etc...)
