The Aeroplane Speaks. Fifth Edition
·
H. Barber
33
Below
is
left
the
Earth
with
all
its
bumps
and
troubles.
Up
into
the
clean
clear
Air
moves
with
incredible
speed
and
steadiness
this
triumph
of
the
Designer,
the
result
of
how
much
mental
effort,
imagination,
trials
and
errors,
failures
and
successes,
and
many
a
life
lost
in
high
endeavour.
Now
is
the
mighty
voice
of
the
Engine
heard
as
he
turns
the
Propeller
nine
hundred
times
a
minute.
Now
does
the
Thrust
fight
the
Drift
for
all
it's
worth,
and
the
Air
Speed
Indicator
gasps
with
delight
"One
hundred
miles
an
hour!"
And
now
does
the
burden
of
work
fall
upon
the
Lift
and
Drift
Wires,
and
they
scream
to
the
Turnbuckles
whose
business
it
is
to
hold
them
in
tension,
"This
is
the
limit!
the
Limit!
THE
LIMIT!
Release
us,
if
only
a
quarter
turn."
But
the
Turnbuckles
are
locked
too
fast
to
turn
their
eyes
or
utter
a
word.
Only
the
Locking
Wires
thus:
"Ha!
ha!
the
Rigger
knew
his
job.
He
knew
the
trick,
and
there's
no
release
here."
For
an
expert
rigger
will
always
use
the
locking
wire
in
such
a
way
as
to
oppose
the
slightest
tendency
of
the
turnbuckle
to
unscrew.
The
other
kind
of
rigger
will
often
use
the
wire
in
such
a
way
as
to
allow
the
turnbuckle,
to
the
"eyes"
of
which
the
wires
are
attached,
to
unscrew
a
quarter
of
a
turn
or
more,
with
the
result
that
the
correct
adjustment
of
the
wires
may
be
lost;
and
upon
their
fine
adjustment
much
depends.
