    Mach 10 jet

    chicopee, you're right saying that this craft would not be able to work. But it wasn't intended for this purpose. Still, an air-breathing Mach 10 engine remains a technological marvel. I'll pass the aerodynamic drag of the vehicle in space, my aerodynamics lectures aren't enough
