When you're building a jet that exponentially accelerates past Mach 6 -- as one does -- you need to come up with a way to get it off the ground. Scramjets, or Constant Volume Combustion (CVC) engines, use compressed air and a reduced nozzle to accelerate planes, and they're a hot technology in aviation. Problem is, you have to get them to Mach 4 before the magic happens. Traditionally, scramjet tests have involved strapping the craft to supersonic jets to get the jet up to speed -- not a very cost-effective solution.
