``And what can the Pilot do to save such a situation as
that?'' said Efficiency.

``Well,'' replied Lateral Stability, ``he will try to turn
the Aeroplane sideways and back to an even keel by means
of warping the Ailerons or little wings which are hinged
on to the Wing-tips, and about which you will hear more
later on; but if the side-slip is very bad he may not be able
to right the Aeroplane by means of the Ailerons, and then
the only thing for him to do is to use the Rudder and to turn
the nose of the Aeroplane down and head-on to the direction
of motion. The Aeroplane will then be meeting the air in
the direction it is designed to do so, and the Surfaces and
also the controls (the Rudder, Ailerons, and Elevator) will
be working efficiently; but its attitude relative to the earth
will probably be more or less upside-down, for the action
of turning the Aeroplane's nose down results, as you will
see by the illustration B, in the right wing, which is on the
outside of the circle. travelling through the air with greater
speed than the left-hand wing. More Speed means more
Lift, so that results in overturning the Aeroplane still more;
but now it is, at any rate, meeting the air as it is designed
to meet it, and everything is working properly. It is then
only necessary to warp the Elevator, as shown in illustration
C, in order to bring the Aeroplane into a proper attitude
relative to the earth.''

``Ah!'' said the Rudder, looking wise, ``it's in a case
like that when I become the Elevator and the Elevator
