> It does mean they technically have an expendable heavy launch vehicle though. That is how they started using Falcon 9 as well: first expendable but testing recovery - which failed several times in several interesting ways - until that process was refined into what now seems to be a normal thing: the first stage launches, drops off a second stage, turns around and makes its way back to either the launch site or a floating platform. I assume they have the same plans for this system: launch expendable while using the hardware to refine the process of recovery until in not that many years from now they launch and land and launch again.
