In one of my old savefiles, Jeb was orbiting Kerbin in an elliptical orbit with an apoapsis of 2Mm (that's 2,000km, folks) and a periapsis of 100km. ... With no electric charge, and not enough fuel to get back to Kerbin even if he could start the engine. This was beginner career, so a rescue mission would not be coming anytime soon. ... I deleted that save. It was just too painful.
