Salutations! I've been playing KSP on and off for the last couple of weeks, but only now having successfully reached (and returned alive from) orbit do I feel justified in admitting myself to the KSP community forum. My rockets were always falling tragically short of orbit, until one of my friends taught me a simple rule of thumb: "However large you think you should make your rockets, double it." I'd like to dedicate this post to the dozens of Kerbals who died to make it possible. Cirius.
