Card Aerospace’s first official program, Orbital Transport (OrbTran) is a program ment to safely get Droods to LDO and back. It is 3 stages, all being recoverable. The first is two gigantic SRBs, the second is a core stage that does not run during liftoff and is ignited after SRB burn-out. The third stage is a vacuum engine that has enough Delta-v to get to orbit and de orbit, even this is recoverable. Then there is a single seat capsule with a trunk believe it or not, this is recoverable as well.
