THREE:Larry had overlooked that point for the instant. It was his only difficulty in flying, to recollect always to control all the different movements together. The joystick, operating the wing-flap ailerons by the left-or-right, lateral movement, also raised or depressed the elevators by forward-or-backward movement. However, in any lateral position, the forward and backward set of the stick worked the elevators and in executing a control maneuver, even as simple as going into a bank combined with a turning glide, or downward spiral, the movement of the stick should be both slightly sidewise, for sufficient bank, and, with the same movement, slightly forward, for depressing the nose into a glide, returning the stick from slightly forward back to neutral to avoid over-depressing the nose into too steep a glide; if not put back in neutral when the right angle was attained, the depressed elevators would continue to turn the forward part of the craft more steeply downward.
