"Man, don’t you think I understand ballistics? For the orbital position then, from query through reply and then to command-received is under four seconds. . . and you can rely on me not to waste microseconds. Your maximum parking-orbit travel in four seconds is only thirty-two kilometers, diminishing asymptotically to zero at landing. My reflex time will be effectively less than that of a pilot in a manual landing because I don’t waste time grasping a situation and deciding on correct action. So my maximum is four seconds. But my effective reflex time is much less, as I project and predict constantly, see ahead, program it out—in effect, I’ll stay four seconds ahead of you in your trajectory and respond instantly."
