It says a lot about the state of hypersonic airbreathing propulsion that
when the X-43 was boosted from Mach 0.8 to Mach 10 by a rocket, and then
managed to briefly not slow down using a scramjet, this was considered a
landmark accomplishment for the scramjet, and utterly unremarkable for the
rocket.

The above is a bit lengthy, but the jist of it would make an excellent .sig.
