1. Obscenely expensive to get them up there, because "you need fuel to lift the fuel to lift the fuel" rockery problem...
2. Guidance during the drop is an unsolved problem - how do you make flaps that don't burn up?

@cjd but it would be so cool. Therefore we need to do it
Hypersonics are almost the same thing, it's just that instead of using rocket fuel to wind up the "gravity spring" and then release it later, you just use the rocket fuel to make the thing go fast fast
@cjd we should rename hypersonics to thor's hammer at least or "rockets from God"
Imagine a nuclear powered ramjet... You just put a bunch of fuel inside of a tungsten crucible (so it can get very hot) and you launch it with a conventional rocket and once it's doing about mach 1 you blow the control rods out of it and let it run by heating the air...
