This here is my very first successful SSTO. It's not much to look at, and it gets a 100x100 orbit with only about a hundred dV to spare, but it works On the plus side, it also has a kethane drill, tanks, and processor in it's little storage bay, so once I've refueled it in orbit, it can expect to get back from anywhere it goes, so long as it lands on a kethane deposit. Here's that cargobay. (Technically this is an earlier version of the ship shown above, but the cargobay remains the same, and this version couldn't make orbit :\ )
