Gah! you\'re almost as evil as Harv with your secrets! Though i have a question about the Ion engine, how would that be different from the current engines we have in the probodobodyne pack? and i wish you luck with the sensors! those are definetly going to be vital once we reach that late stage when Harv adds all the other planets and stuff. Much better (and safer) to send a probe to a distant planet to find out its gravity and such so you can plan a mission then some poor kerbounatuts, doomed to play chicken with a hunk of rock. x] I\'m guessing once Harv has figured out how to implement un-manned flights, all the probodobodyne cores will be un-manned, correct?
