Expanding on your technique I figured out how to launch kerbals into space too. I'm planning on explaining in a YouTube video soon. In case you cant read that, that is 6,130,561.6 meters per second, or approximately 2% the speed of light. Our speed is really only limited by our computer's ability to process a ridiculous amount of decouplers. I'm trying to figure out something cool to do though, launching kerbals and struts into deep space is fine and all, but I feel like I need some crazy goal besides speed alone. There are a few ways I can influence exactly where the kerbal is launched. Just sending kerbals to their speedy doom on celestial bodies seems mean spirited though. Any ideas?
