A kerbonaut with a double name, whose presence on the ship "Inspiration of the Windward Spirit" about to burn spectacularly in the corrosive atmosphere of a green gas giant, is justified only by the fact that he is the only one who can launch the probe[1] from the cargo bay for independent flight into space. Oddly enough, Billy-Bobmon has a practically minimal reserve of "courage" which certainly raises doubts about his voluntary presence on this ship. In the "Jool Aerobrake" scenario, he has level 5 (★★★★★) in the engineering specialization. He sits in the pilot's seat of the command moduleMk2 Lander Can by the window and apparently controls the ship. Incidentally, in the window with Billy-Bobmon's portrait in the lower right corner of the flight screen, you can see a bored-looking scientist, Rodfurt Kerman, sitting behind Billy.
