Good points, Pattern.
I seem to remember a plane that could get to Mach 3+ from a standing start using a modified jet fuel, then reaching Mach 3+. So maybe this concept could be used in a fairly large plane that used basic turbojets initially, light up the new, cosmic motor.
What I do not like is a hybrid that has to have its own oxidizer versus the "free" air we get with our current motors.
Gonna be interesting, huh?
