From earlier contexts, I assumed that we were talking about using jet engines at supersonic speed. And supersonic inlets are not a stock item.
You almost certainly wouldn't want a supersonic flyback booster whichever form of jet you used, too much drag, hence too much fuel needed. I was talking about a mach 0.8 ramjet on cost grounds, not performance.
In that case, Randall is right, but not for the reasons he thinks he is. A subsonic ramjet is a almost as big a fuel hog as a rocket. Therefore, I assumed if you were talking ramjets you must be talking supersonic.
