Jebediah Kerman, Test Pilot extraordinare.
Or if he was a Golden Age kerbal pilot, now long departed and much mourned, his spiritual descendant: MechJeb! The only Autopilot that can fly a Valkarie through and out the envelope and back in the other side.*
*MechJeb is not actually that good of a pilot-do not engage MechJeb in docking mode and go prepare snacks, leaving the autopilot unsupervised. Do not attempt to program a suicide burn landing profile. Do not attempt to use Mechjeb without calibrating it to local atmospheric conditions. Do not scream at MechJeb. Do not ask MechJeb to Open the podbay doors. Use of MechJeb with third-party navigation data invalidates the warranty and absolves Anatid Robotics and Multiversal Mechatronics of all liability for accidents and collisions. Please use Mech-jeb responsibly.
