   Catching up on some unread journals, I note that the March/April 2003   
   issue of JBIS has a very interesting paper:  "A comparison of propulsion   
   concepts for SSTO reusable launchers", by Richard Varvill and Alan Bond.   
   While the authors have a mild case of hydrogen religion -- non-hydrogen   
   rockets are never mentioned -- and they obviously have their own axe to   
   grind, they generally give a good overview of the alternatives, including   
   why scramjets are such a lousy idea for space launch.
