The Aeroplane Speaks. Fifth Edition

"Well,
what
do
you
think
of
that?"
they
all
cried
to
the
Drift.
"You
think
you
are
very
clever,"
sneered
the
Drift.
"But
you
are
not
helping
Efficiency
as
much
as
you
think.
The
suction
effect
on
the
top
of
the
lower
Surface
will
give
a
downward
motion
to
the
air
above
it
and
the
result
will
be
that
the
bottom
of
the
top
Surface
will
not
secure
as
good
a
Reaction
from
the
air
as
would
otherwise
be
the
case,
and
that
means
loss
of
Lift;
and
you
can't
help
matters
by
increasing
the
gap
between
the
surfaces
because
that
means
longer
Struts
and
Wires,
and
that
in
itself
would
help
me,
not
to
speak
of
increasing
the
Weight.
You
see
it's
not
quite
so
easy
as
you
thought."
At
this
moment
a
hiccough
was
heard,
and
a
rather
fast
and
rakish-looking
chap,
named
Stagger,
spoke
up.
"How
d'ye
do,
miss,"
he
said
politely
to
Efficiency,
with
a
side
glance
out
of
his
wicked
old
eye.
"I'm
a
bit
of
a
knut,
and
without
the
slightest
trouble
I
can
easily
minimize
the
disadvantage
that
old
reprobate
Drift
has
been
frightening
you
with.
I
just
stagger
the
top
Surface
a
bit
forward,
and
no
longer
is
that
suction
effect
dead
under
it.
At
the
same
time
I'm
sure
the
top
Surface
will
kindly
extend
its
Span
for
such
distance
as
its
Spars
will
support
it
without
the
aid
of
Struts.
Such
extension
will
be
quite
useful,
as
there
will
be
no
Surface
at
all
underneath
it
to
interfere
with
the
Reaction
above."
And
the
Stagger
leaned
forward
and
picked
up
the
Chalk,
and
this
is
the
picture
he
drew:
