Like most people here I don't like the idea of experienced kerbals simply improving their rocket's stats. But I do want a valid reason to invest in a karbal, keep it alive and always retrieve it. So here's my idea on how it would work: Zero experience kerbal - you fly the rocket yourself, like in current version. It's pilot needs to watch & learn. Some experience - your ship can fly straight and steady, and you don't need to keep "babysitting" through your 20 min' long burn. (the more experienced, the steadier) just hit the gas, lean back & watch. More experienced - you would have the option to have the pilot perform the maneuver himself, by the maneuver node which you have set. The more experienced, the more accurately the maneuver is performed. And of course you should have the option to "override control", for those who refuse to have their ships flying themselves :] ... And please, ditch the idea of kerbals improving rocket stats... I don't wanna have to pick my least favorite kerbal each time I want to prove my crafts' capabilities 8-[
