Jeb : _ Bill, she's accelerating pretty quick, damnit! Did you tuned up that RAPIER or what? Should I be worried? Over

Bill : _ (Giggles) Nah, she's just clean skin now. Very little drag - watch for structural over-stress and over-temp, tough: at this acceleration, it will be pretty easy to reach them! Over
