On Fri, 14 Dec 2007 23:23:55 -0800 (PST), in a place far, far away,
made the phosphor on my monitor glow in such a
way as to indicate that:

There has been lots of interest in Scramjets because of their
potential to lower the cost of access to space, or Single Stage to
Orbit as a means of lowering cost of access to space.

Yes, a lot of mistaken interest in them. Scramjets, or any other
airbreather, are unlikely to be the solution to low-cost launch.
