I suspected it might be something like that - the idea's been around for a long while - I guess that in 1982 it's even been a long while since the DynaSoar. Heinlein was using the Skip-to-M'Lou idea in the 40's. Why didn't the shuttle use the Dyna-Soar concept? Was it proved unsafe? Surely it must have been studied, since the tiles were giving such problems in the mid '70's that a lot of people were certain that the shuttle would never fly. Finally, if we can't make the DynaSoar work, is there any reason to suppose that the Russians can?
