   Beside the problem of handling cryogenic fuels, it doesn't make sense to   
   carry your oxidizer when it's all around, holding you up.   
      
   And sure, H2 is lighter than jet fuel, but that just means *really* big   
   fuel tanks, and they're going to be heavy, since they have to contain   
   seriously cold liquid without letting it boil away.
