This time on
"Impossible Engineering,"

a rocket-powered
speed machine...

It's the pinnacle
of all land-speed cars.

Supersonic engineering...

It's designed to produce
200,000 horsepower.

That's more power
than the entire grid

of a formula one race.

And the pioneering
historic innovations...

It's incredible
to think this was once

the fastest car in the world.

Oh!
My god.

Similar to what Fritz did
with the rocket car.

That made
the impossible possible.

The black rock desert,

a barren wilderness in Nevada...

The setting for one of
the most awesome challenges

known to mankind...

The land speed record...

engineering
at its most extreme...

which, in 1997,
took the British Thrustssc

to a mind-blowing
763 miles per hour...

A record that has

remained untouched
for over two decades.

Yeah!

But now, in Perth, Australia,

an ambitious team is building
a car that they believe

will one day re-write history...

The Aussie invader.

Well, here she is,

soon to be the world's
fastest car...

Aussie invader 5r.

55 feet in length,
6 1/2 ton in weight.

Very, very powerful...

200,000 horsepower,
62,000 pound of thrust.

This extraordinary machine

is the culmination
of a life's work

for inventor and driver
Rosco McGlashan.

Well, I believe
this car is the most innovative

land-speed car ever conceived.

This baby here is a solution
to going very, very fast.

This car... it's perfect.

It got everything
in the right place.

It's a revelation.

To create a car
as fast as a speeding bullet

requires NASA-like technology.

Keith and Jenny Lovatt
are part of the team

striving to create
this engineering first.

This is absolutely
one of the most exciting

high-speed car projects
in the world.

The dynamics of the car
do share with aerospace...

The rocket engine,
the wheel speeds.

Even the paint finish on the car
has to be able

to cope with super-high speeds.

Aussie invader's
futuristic bodywork

has just been completed.

The team is now working on
its propulsion system.

But this will not only have
to break the land speed record.

Incredibly, Rosco has another

audacious goal in his sights.

The next big thing
that we want to achieve

in the land speed record is

what we say is the holy grail
of auto racing...

1,000 mile an hour.

To achieve 1,000 mile
an hour in a car,

or 1.4 mach, is impossible,

and that's why we're doing it.

We love it.

This is a one-off,
absolute unique car.

Aussie invader 5r
is the ultimate of cars.

Aussie invader
is constructed around

a unique steel tube.

Two huge fuel tanks feed

a liquid-propellant rocket
engine powerful enough

to break the sound barrier
in 15 seconds...

Before state-of-the-art
air brakes

and a parachute system

bring this horizontal rocket
to a halt

at the end of its 15-mile run.

- That's good here. Yep.
- 12-volt.

But as this pioneering team

looks to enter the unknown,

the challenges are immense.

How is it possible to create
fighter-jet performance

on four wheels?

To make a car go
as fast as we want to go,

which is 1.4 mach,
you need a heap of power.

How do you ensure

Aussie invader
won't break apart?

It has to be made

to withstand some
extreme forces.

1,000 miles an hour,

with wheels turning
at 10,000 R.P.M.,

strange things happen.

And how can it safely slow down

from supersonic speeds?

It has been a challenge

to develop a braking system
for the car

because there is no book
that tells us

what we need to do.

The fact that few
have even attempted

to travel this fast on land

poses, perhaps,
the biggest problem.

I think that
three times as many people

have gone to the moon

than have gone
600 mile an hour in a car.

So, that's a pretty amazing
thing to achieve.

So, how do you even
know what shape to build?

A lot of people say to me,

"how do you make a car go
1,000 mile an hour?

What's the difference between
a 1,000-mile-an-hour car

and my road car?"

Obviously, the aerodynamics,

making the car stay
on the ground...

It's just got to have
the right load

on the ground at all times.

And the aerodynamics
are, possibly,

the major thing to get right.

For inspiration,

the team looks to
an innovator of the past,

Belgian car manufacturer
Camille Jenatzy.

Like Aussie invader,
he had to come up

with something
completely different.

Andrew Steele has come

to the Ccit� de l'automobile
in Mulhouse, France,

to get up to speed with
Jenatzy's inspired solution...

a totally new breed of car.

This is a full-size replica

of that incredible vehicle.

It's called la jamais contente,

which means
"the never satisfied."

And it was a revolution
in automotive engineering.

This was the first-ever car

specifically designed
to break the land speed record.

And in 1899, it did just that,

breaking
the 62-mile-per-hour record.

Here we go!

The Jamais Contente's
bullet-like design

broke the mold
of automobile-era dynamics,

the kind of forward thinking

that Aussie invader
will have to adopt.

What a machine.

In Perth, a team of engineers

is constructing
a one-of-a-kind car

that they hope could reach

an earth-shattering
1,000 miles per hour.

Like Camille Jenatzy,

inventor and driver
Rosco McGlashan's life

is focused on one thing.

The land-speed record
has been something

that I've wanted to achieve
all my life.

Quit school at 12 years of age
to set the record,

and here I am,
many, many years later,

still chasing that elusive goal.

Rosco's quest for speed

began with homemade go-karts.

As an adult, he upped the ante.

Raced things like
rocket-powered motorcycles,

jet dragsters...

A lot of stuff.

In the 1990s,

Rosco would earn himself
legendary status

as he targeted the Australian
land speed record.

Initially,
what we wanted to do is,

I want to claim the title
of fastest Aussie on earth,

and it took us some time
to do that.

- Yeah. How you doing, mate?
- Good, mate.

And that looked
really spectacular.

- Looked really beautiful.
- It looks good, man.

Wasn't till '94
that we actually set the record

at 500 mile an hour.

The average speed
for the two runs was

801.3 kilometers per hour.

We can bring the champagne.

So, we've got it, guys!
We've got it!

Now he believes
his new, groundbreaking design

has the potential to become
the fastest car on the planet.

As with Jenatzy's
bullet-like innovation,

the starting point for Rosco
is creating the right shape.

I thought,
"if you want to go to the moon,

you start off with
a cylindrical object,

have a point at the top of it,
rocket motor in the bum,

pressure vessels
all the way through,

and you sit under
the point at the top."

Well, obviously, in a car,

we want to be sitting on
the center of gravity.

So, center of gravity
is about here,

and we're sitting
right behind it.

So we know what the car's doing.

So, obviously, if the front
of the car's moving,

if the back's moving,
we want to know about it.

Aussie invader's nose
is angled down to avoid lift.

To house the rocket's
huge fuel tanks,

a unique 40-foot-long steel tube

forms the car's
colossal front cylinder.

What we call the mainframe is a
pipe, if you like.

It's been dimpled to get

the right boundary layer,
airflow over it,

and if you measure this car

from the front axle
to the back axle,

it's possibly 2-mil difference.

So, it's strong there.

I think
it's the perfect solution.

To reach 1,000 miles an hour,

Aussie invader's
cylindrical body

would have to cope
with some extreme forces.

Approaching the sound barrier,
or supersonic travel,

would disrupt the airflow,

causing a potentially
devastating problem

underneath the car.

To keep the car on track
to break the land speed record,

engineers will have
to get creative

and make the impossible
possible.

Taking a car
to a record-breaking

1,000 miles per hour

comes with some
unique challenges.

For example, the intense
airflow disruption at that speed

could be enough to throw
the Aussie invader

dangerously off course.

Just before
it's approaching supersonic,

there's a shock wave
that forms on the car.

The problem with the car is,

it cannot dissipate
that shock wave downwards

because it hits the ground.

And if you've got a flat belly
underneath the car,

it'll go "bang, bang, bang,
bang," all the way down.

These trapped shock waves

could throw Aussie invader
dangerously off course,

so the team came up with
an ingenious solution.

We made
a "V" underbelly on the car.

The further back it goes,
the sharper it gets.

So, as that shock wave moves
backwards,

the shock wave then dissipates
off the side of the car

and go outwards instead
of hitting the ground

and bouncing back on the car.

Aussie invader
is aiming to travel

five-times faster
than a crossbow bolt,

four-times quicker
than an Indy 500 racing car,

and double the cruising speed
of an airbus A330.

But to achieve this,
it will have to generate

more thrust than any other car,

creating a massive problem

for inventor and driver
Rosco McGlashan.

I'm in the speed business,

so we want to go
really, really fast.

We believe we need
62,000 pounds of thrust

to get us to where
we want to go,

to the 1,000 mile an hour,

and there's not many ways
to get that.

Land speed records have been set

with a wide range
of power sources.

In the '60s,
the American goldenrod

was fitted with
four combustion engines.

But its piston-powered record

was 600 miles per hour short

of Aussie invader's
1,000-per-hour target.

Engineering greats,
like spirit of America,

were fitted with turbo jets.

But these are not
the ideal solution for Rosco.

The things
that scare us with jets

is where the engines will
suck in like a big...

Or a stone or a rock or a wrench
into the engine,

kill the engine,
you lose the record.

So we're done with jets.

So, what could
propel Aussie invader

to its impossible dream?

Can the pioneers of the past
help out?

In Dudenhofen, Bavaria,

a test track is playing host

to an engineering masterpiece
that could help Aussie invader.

Behind the wheel is
vintage car specialist

Uwe Mertin.

This car was originally
driven in 1928,

and to drive it here now,
90 years later,

it's just amazing
to have this chance

to be here
and to drive this car.

This is a replica of the
legendary Opel Rak 2.

Its extraordinary wings
give a clue

that this was no ordinary car.

The original car had
a kind of a different...

You can't really say engine.

It was just powered
in a different way.

With the sole goal
of out-and-out speed,

the car maker's
director of testing,

Fritz Von Opel,
replaced the combustion engine

with something quite incredible.

What you see here
are 24 rockets.

And imagine...
There was no engine inside,

no transmission,
just the rockets

and the driver
at the steering wheel.

That was it.

And then bringing up this car

to a speed of
238 kilometers per hour,

it's just amazing.

Von Opel used
solid fuel rockets.

Once lit, their powdered
propellant burnt outwards,

releasing high-speed gases,

propelling the car with
6.6 tons of thrust.

Whenever they were ignited,
it was like fireworks.

The driver ignited,
with a pedal,

always four rockets at a time.

So, 24 rockets,
he had to do it 6 times,

and the car went faster
and faster and faster,

up to the end speed.

To appreciate the
rocket's phenomenal performance,

Uwe has a scaled-down
demonstration.

So, in my hands,
I have three solid fuel rockets.

Put the rockets on here.

Let me see.

And when three fuses
are slotted into place,

today's mini rocket car
is ready for launch.

So, I'm gonna
light the fuse now.

Whoa!

My god.

Similar to what Fritz did
with the rocket car.

In 1928,
at a Berlin racing circuit,

these awesome rockets
would launch the Rak 2

into the record books with
its 148-mile-per-hour top speed.

There was tons of smoke.

There was a big, like,
fire wall coming towards you.

It was really the first time

that people had seen
something like this.

Fritz Von Opel is, for sure,

a pioneer and a German hero.

Aussie invader
is following in the footsteps

of the remarkable Rak 2.

But it's single rocket
is being built to drive it

almost seven times faster than
its land-speed predecessor.

So, this is the solution
to all our power problems.

It's a bipropellant
rocket motor,

and it's designed to produce
around 200,000 horsepower.

That's more power

than the entire grid
of a formula one race.

This bipropellant
rocket is engineered

around two liquids...

An oxidizer,
white fuming nitric acid,

and turpentine,
which acts as its fuel.

Nitrogen gas stored
in three giant tanks

pressurizes the two liquids
at 600 psi.

When the throttle's opened,

the liquids are released
into the combustion chamber.

Soon as they see each other,
it's instant oomph.

There's a massive

controlled explosion
inside there.

It gets squeezed through here,

which puts a massive amount
of pressure through the throat

and then out through the nozzle.

The same scenario is when
you're watering the garden,

you put your finger over there,

you restrict the flow
at the end of the hose,

and, obviously,
the pressure goes up massively.

Testing of the
rocket's cutting-edge fuel is

currently underway at a facility
in the Mojave desert.

When white fuming nitric acid
and turpentine

are injected together,
the result is spectacular.

5, 4, 3, 2, 1.

On land, it's hoped
this extraordinary thrust

will allow Aussie invader

to cover over 1,400 feet
in just one second.

When I hit the gas pedal
on this car,

the two mixtures go
into the combustion chamber.

The two mixtures puts out
a plume 300 foot out behind it,

makes full power
in 3 milliseconds.

And the temperature inside there

gets close
to 2,000 degrees Fahrenheit

Within seconds.

That's space technology.

Rockets are the only way to go.

Rocket engineering
could one day fire

Aussie invader into
the land-speed history books,

but it's fuel-guzzling
performance

creates a major problem.

With the
propellent usage on the car,

the car's getting 2 1/2 ton
lighter in 21 seconds.

This could make
the Aussie invader

dangerously unstable.

What can actually happen is,
the car can just lose

its directional control
and spin like a top,

either way sideways.

Australian inventor
and racing legend

Rosco McGlashan is on
a mission impossible...

to create the world's
fastest car ever.

I'm no rocket scientist,

but I've got rocket scientists
that help me.

I've got engineers.

I've got welders.
I've got fabricators.

I've got the best
you can possibly get.

There's a steering tunnel

that mounts off a rock
on the inside here,

which gives us
five degrees here.

Just give her a turn.

Would you like?

Just... so, it puts it actually

through a five-degree plane
either way.

And that's the best
available steering we have.

To date, Aussie invader has been

15 years in the making.

Its designers hope it will
one day reach a mind-blowing

1,000 miles per hour
in just 20 seconds,

making it an engineering first.

There's not a lot of people
that can tell you

how to do this or work it.

There's no land-speed book.

There's no rocket car building
project kit.

You have to start from scratch
and work forward.

The 10.4-ton
Aussie invader will

be rocket-propelled,
capable of creating more power

than two hornet
fighter aircraft.

Its engine is 1,300 times
more powerful than a family car,

engineered to travel one mile

in an astonishing 4 seconds.

I think the greatest thing about

what I'm doing is,
no one else is doing it.

It's too hard.

It's the most impossible thing
you could attempt to do.

Aussie invader's
projected speeds are staggering,

but driving this fast would
create an immense problem

for a crucial part of the car.

So, 1,000 mile an hour,

our wheels are gonna turn
at 10,000 R.P.M.

So we cannot run tires.

It'd just explode.

So, one of the biggest obstacles
we've had to overcome is

having wheels that would turn
at that R.P.M.

The space-age solution

is a set of super-strong
aluminum wheels.

Engineer Mal Austin
is overseeing their development.

Essentially, it's one of a kind,

so you're not going
into production

with these type of wheels.

You have a 900-diameter piece
of solid aluminium

turning at 10,000-plus R.P.M.

The forces at play
are astronomical...

Hence, being the toughest
grade of aluminium

we could possibly find.

Any slight stone or anything
it may hit upon the track,

it puts an immense lot of force
onto the wheel.

It's got to relatively
stand a lot of load.

These unique wheels
are built to withstand

an unbelievable 50,000-G.

Being machined
out of one solid piece

is the only way to go.

It provides with
the right tensile strength.

This weighs approximately
140 kilos.

There's no ring to that.

So, it's pretty solid.

But if Aussie invader

is ever to achieve
a safe supersonic run,

it will have to overcome
another huge challenge,

a problem that nearly killed

the pioneering record holder
Donald Campbell

in the legendary bluebird.

Donald Campbell,
back in about 1960,

ran his bluebird racer,
and he found that

the back of the car came
'round past the front.

So, the car couldn't
run like an arrow.

It's thought that
instability at high speed

caused the catastrophic crash.

Unwanted lift had nearly
cost Campbell his life.

Now Rosco McGlashan
faces the same danger.

To keep Aussie invader
safely on the ground,

its center of gravity must
be perfectly positioned.

Achieving this
with a rocket-powered car

is far from easy.

With the
propellant usage on the car,

the car's getting 2-1/2 ton
lighter in 21 seconds.

What happens...
The center of gravity on the car

is moving rearwards.

And what can actually happen is,

the car can just lose
its directional control

and spin like a top
either way sideways.

Can an innovation from the past

offer a solution
to avoid disaster?

Formula one pit engineer
Michelle Creighton

is used to life
in the fast Lane.

Today, she's at
the British motor museum,

discovering a racing icon

that could provide an answer
for Aussie invader.

Wow. This is the beautiful,
stunning Jaguar d-type.

This is the car that raced
at Le mans in 1954.

It's engineering at its finest.

It's so smooth.

It's made out of one piece
of lightweight aluminium.

It is all handcrafted,

and it is absolutely
beautifully finished.

Absolutely stunning.

Despite its slick lines,
to beat the world's best

at the grueling 24 hours
of Le mans,

the Jaguar team needed all-round
super-fast performance.

But high-speed sections,

like the nearly four-mile
Mulsanne straight,

were posing a problem.

When traveling over
170 miles per hour,

the D-type's lightweight body
was becoming unstable.

Jaguar knew, to compete,

their engineers have to come up

with something game-changing

and iconic to stand a chance.

Aerodynamicist Malcolm Sayer had

a simple solution to help the
d-type reach the checkered flag,

an invention that could also
assist Aussie invader.

Formula one
pit engineer Michelle Creighton

is at the British motor museum

to see how the pioneering
Jaguar d-type design

could help the engineers
behind Aussie invader.

This is what this car
so iconic...

The tail fin just behind
the driver's head.

Aerodynamicist Malcolm Sayer

was the innovative mind behind

this revolutionary addition
to automotive design.

The tail fin is
designed specifically

for high speeds.

Going down
the Mulsanne straight,

you're doing 170 miles an hour.

You don't want any crosswinds
to knock this car.

The tail fin is just like
a fin on the plane.

It's gonna help the stability
of the car.

Wow, the feeling of this car
is unbelievable!

The sheer speed and the power,
it's just phenomenal.

This brilliant innovation

made the d-type rock-solid
on the high-speed straights.

Its impact is down
to the relationship between

the car's center of gravity

and center of pressure,
the point where lift acts.

With no ring,
the two are roughly centered,

creating instability.

By increasing the car's
surface area with a fin,

the center of pressure
moves further back,

controlling lift
and creating stability,

science that can also be seen
through a demonstration

by world-class Archer
Caitlin McCarthy,

first with a feathered arrow.

When you're ready, Caitlin.

Oh! Nailed it.
That was a wicked shot.

But when the crucial
surface area of the feathers

is removed...

Wow!

It's a different story.

With the feathers
or the fletchings on the back,

the arrow has completely
gone off course.

Just proves how vital
those feathers are

and the fin on the back
of the d-type.

In the '50s,
the Jaguar's game-changing fin

helped to increase
the D-type's top speeD

from 172 to 192 miles per hour
on the straight,

powering it
to a historic hat trick

of Le mans wins.

This kind of success
back in its day and age

was unheard of.

It absolutely dominated Le mans.

The fin is a great achievement.

Aussie invader's team

is building on the D-type's
ingenious concept.

After months
of prototype testing...

So, that man there
is responsible for that.

Look at that.
Whoo-hoo.

The final result
is a state-of-the-art tail fin

that they hope will one day
keep Aussie invader stable

at five times the speed
of the historic Jaguar.

So, here she is.

Here's our vertical stabilizer
mounted on top.

Without this component
on the car,

this car could not run straight.

Sort of a bit like the rocket,

the back end would want
to pass the front

and turn around itself.

As with the Jaguar,
the tail fin's surface area

keeps the crucial
center of pressure

to the supercar's rear.

At around 400 miles per hour,

aerodynamic loads will want
to spin Aussie invader around,

but the tail fin's
intricate profile

creates an opposing force

to this immense
sideways pressure...

while a new innovation
on the top of the tail fin

will counteract lift.

The horizontal stabilizer works,

basically, opposite
to an aeroplane wing.

When it's going through the air,
it's creating a downforce

of pushing them back down.

And the beauty of this one
is that

if we have too much downforce
on the back of the car,

we can actually change the pitch
on that horizontal stabilizer

to the desired loading
on the back axle.

But at super-high speeds,

Aussie invader's front end

will also face a major
aerodynamic challenge.

With 2 1/2 tons of propellant
burnt in just over 20 seconds,

the front's balance
will continually change,

making it potentially unstable.

So, to compensate for that...

The front getting lighter...
What we've got are canards

on the front that are
computer-controlled.

The canards are
small, pitchable wings

positioned behind the wheels.

As the weight comes off
the front wheels,

we get more wing put into it.

The wing cranks down

and pulls the nose down
a bit harder.

The canards at the front
help us with that.

That's a fine balancing act

to get the car to run
perfectly straight.

And all I can say about that is,

this is the slickest
land-speed car

that's ever been built.

And Rosco thinks it's capable

of going the distance,

but it will take
groundbreaking engineering

to make his dream a reality.

Inventor and driver
Rosco McGlashan has assembled

an ambitious team of engineers

to pursue his dream
of driving the first car

to break 1,000 miles per hour.

Rosco is probably a pioneer

in the idea that a car can
go 1,000 miles an hour.

He's dedicated to the point
where he's willing

to put his life on the line
for it.

Over a decade of development has

gone into Aussie invader.

When construction is complete,
Rosco will be more than ready

for his attempt
at the impossible.

62,000 pounds of thrust
could launch this supercar

to the magical
1,000-miles-per-hour Mark

in just over 20 seconds.

But then the engineers will
face their final problem.

With the development of the car,

the slowing of the car has to be
a critical area of it.

From 1,000 mile an hour,
to keep it in a straight line

once the engine power goes off
will be a challenge.

The distance is critical.

He needs to allow himself

plenty of distance
or time to stop.

If they brake this
10 1/2-ton machine too suddenly,

Rosco will experience
up to -16 "G"

and could simply black out.

The difference between
stopping a fast light car

as opposed to a fast heavy car
is a world of difference.

Conventional brakes
are out of the question.

Everything's got
to happen in the right sequence,

going down from 1,000 mile
an hour back to zero.

That's a major job.

Surprisingly,
it's an aeronautical innovation

from the past that
could provide a solution.

One last check of the controls.

And we got full throttle.

In Idaho, former
U.S. Navy flight surgeon

Dr. Rich Sugden is taking
control of the FJ-4b fury...

Gears coming up.

A 1950s trailblazer
that holds a key

to solving
Aussie invader's problem.

Astonishingly,
this 60-year-old jet

can virtually reach mach 1.

But for the engineers
who built it,

slowing it from these speeds

was perhaps
their biggest challenge.

Jet aircrafts need to be
slowed down for two reasons...

First, to land,
and then secondly,

they have to be slowed down

in certain phases
of maneuvering.

The FJ-4b was designed
to be a nuclear bomber,

and part of that design required

that it make a very steep dive
from fairly high altitude.

Okay. We'll be taking it
all the way to the end.

This high-speed
maneuver hurtled the jet

towards the ground
at around 460 miles per hour.

Controlling this dive
posed a major problem.

You need some way
to slow down quickly

in an airplane that's going fast
and is very slick,

has very little drag.

And you have to have something

that can withstand
high stresses.

This seemingly
impossible problem taxed

the greatest aeronautical minds.

But Edgar Schmued
and his team of design engineers

at north American aviation

equipped the FJ-4b
with a brilliant solution.

They're known as air
or speed brakes.

So, these are
the outboard speed brakes

that come out
when the gear is down.

And in addition,
there are ventral speed brakes

that come out on both sides,
that stick down.

When diving on a target,

all four air brakes
were engaged,

greatly increasing
drag resistance.

This allowed the plane to slow

from around 500
to 200 miles per hour

in a matter of seconds.

So, the speed brakes
are electrically controlled,

which means it's just a switch
that opens a valve.

And then 3,000 pounds
of hydraulic pressure is used

to force these speed brakes
out against the air.

And doing 600 miles an hour
through the air,

there's a lot of force
against these things,

so there'd be no way to do this
whole thing mechanically.

These robust engineering marvels

helped transform
high-speed jet performance

and still play a crucial role
in the world of aviation.

So, how can the engineering
behind this 1950s plane

help Rosco's team
bring Aussie invader

to a controlled stop?

Rosco McGlashan
and his innovative team think

they've found a way
to get Aussie invader

up to speeds of
1,000 miles per hour,

but they also have to bring it
back down to a standstill,

and they're turning
to Edgar Schmued's

groundbreaking 1950s
air-brake design to do it.

So, at 1,000 mile an hour,

I pull both throttles back,

and the car will go
from 1,000 mile an hour

back to around 850 mile an hour.

At this critical point,
Rosco will gradually engage

his unique air-brake system...

The first phase of slowing
Aussie invader down.

Then I start inching
the air brakes.

I hit the button...
One, two, three, four, five,

six, seven, eight,
and then fully open.

Electrical engineer
Barry Fitzsimmons was

involved in constructing
these engineering marvels.

The air brakes are
extremely important.

They allow us to get away with
about a 27-kilometer-long track.

Without them,
yes, it would slow down,

but it would take
an awful lot longer.

A series of small holes
stops the air

from easily sliding over
the air brake

by firing the airflow
in different directions,

increasing braking efficiency
by 30%.

The air doors themselves
are extremely robust

because they're gonna be
deployed into an airstream

at very high speed.

If one of these air brakes
opened without the other,

it would slue the front
around dramatically.

So they have to both
open in sequence,

and that's achieved by having
a single hydraulic ram

connected to the two hinges.

They either both work,

or they both don't work,
which is great.

So, that took about
a year to design.

Getting these made was...

A beautiful piece
of engineering.

Keith and Jenny Lovatt
are responsible

for Aussie invader's
second phase of braking...

The parachutes.

So, we would initially expect to
drop the main high-speed chute

out at around 800 mile an hour.

It'll probably work all the way
down to 600 mile an hour.

You'll see that
the top is vented,

where it's allowing the air
to go through.

This is very similar
to what you see

in a space shuttle landing
or a space capsule coming down.

The chute not
only acts as a brake.

Its length also helps maintain
a straight course.

If the car started,
at high speed,

to get sideways,
pull the chute out,

and this will suddenly
give it greater stability,

because it, effectively,
makes the car

from its 40-odd feet now
to over 120 feet,

because the parachute
will be well back there.

It's like a sea anchor.

It'll help pull things
into line.

Three, two, one. Fire.

Drogue guns have been developed

to launch the chutes.

Deployment takes
just a quarter of a second.

Following the high-speed chute,

a second, low-speed parachute
is triggered

at around 400 miles per hour,

further decelerating
Aussie invader.

With the end of its
15-mile run in sight,

the final system,

a set of rear-mounted
disc brakes,

can then be engaged.

If he can get the car
down to 250 mile an hour

before he uses the wheel brakes,

that would be best
simply because

it's wear and tear on the car.

We expect to run it
a number of times

to get up to a speed record.

Through ambitious design

and innovative engineering,

Aussie invader may one day
change land-speed history...

The whole car makes me
very, very proud

because is like
a 10-years accumulation

of seeing it all come together.

You stand back and think,
"god, did we really do that?"

Overcoming extreme challenges

to take on
the seemingly impossible.

I've spent my lifetime
putting it all together,

and I can't wait
to sit my bum in that car

and light the wick.

By building on the work
of the pioneers of the past...

Whoa!

Adapting and breaking
the mold themselves...

The car has come of age.

I believe it's gonna
set the world on fire,

gonna be the first car
in the world history

to go 1,000 miles an hour.

The engineers are succeeding

in making the
impossible possible.
