The first successful SSTO I've ever produced. Slightly resembles the SR-71, hence the title. I've constructed three separate variants, a cargo, and docking variant, as well as one capable of holding 6 Kerbals. :(:( As far as my capability goes flying the craft I was able to get this thing into a stable 100KM orbit. I have yet to stress test each variant, but will plan on doing so in the future.
