In today's impossible engineering.

This is the most groundbreaking, cutting -edge, innovative aircraft that I've

ever seen.

A one -of -a -kind, shape -shifting military machine.

The Osprey is definitely one of the most amazing vehicles in the sky.

It has the ability to do things that no other aircraft can do.

This aircraft is giving us the capability we've never had before by

both an airplane mode and a helicopter mode.

and the pioneering historic innovations.

All right, so you ready to fly? I am.

Thank you, sir.

It's incredible to be standing here. This is four acres of floating aviation

history that made the impossible possible.

At New River Air Station in North Carolina,

Marine Corps Squadron 266, a .k .a. the Fighting Griffins, are preparing for a

complex training mission.

It's designed to test their ability to overcome the challenges

of modern military operations.

In today's battlefield, it's constantly changing.

We never know what operating environment we're going to have to confront,

whether it's the desert, urban environment.

or arctic weather confronting america's adversaries we need to be able to

understand decide and act our ability to do that quickly and act quickly with

adaptability and flexibility will be key to our success and when it's time

for the marines to enter the action they can rely on an aircraft that's capable

of the ultimate adaptation one that was long thought impossible

This is the V -22 Osprey, a revolutionary

feat of aviation engineering that combines the speed and range of an

with the land anywhere capability of a helicopter.

It's a multi -mission powerhouse that allows the U .S. military to perform

crucial operations in challenging conditions all over the world.

This aircraft, in my opinion, defines the 21st century Marine Corps.

The Osprey is truly impressive.

When I look at it, I am blown away by the technology and the capability it's

able to produce.

The MV -22 can fly as high as 25 ,000 feet and hit 280 knots.

We can carry 12 ,500 pounds externally and has a range in the ballpark of 750

800 nautical miles.

Nothing can compare to the Osprey.

It's one of a kind, and I love it.

Equipped with a pair of 38 -foot rotors, the Osprey can take off vertically like

a helicopter, pivot its blades forward, and transform into a propeller -powered

airplane capable of carrying 24 fully loaded combat Marines.

and flinging the equivalent weight of an African elephant beneath the fuselage.

It's the ideal aircraft for flying troops and cargo into tough -to -reach,

dangerous locations.

For Marine Colonel John Spade, the Osprey is an invaluable tool that's

redefine how his team can operate.

Our ambition as Marines was to be able to project power.

Well forward.

The V -22 Osprey was created to achieve and accomplish that ambition.

This aircraft is giving us the capability we've never had before by

both an airplane mode and a helicopter mode, which allows us to quickly respond

to emerging situations that are in front of the Marine Corps right now.

And this game -changing machine is pushing the boundaries of what's

American armed forces.

Unlike any other aircraft, we can take off vertically,

transition airplane mode, get to great distances at great speed, and land

vertically again.

This allows us to get those off -steer locations quickly and with great

response.

Engineers have built a world -class aircraft with matchless capabilities.

But how do you design a vehicle that can transform from helicopter to airplane

in flight?

The capabilities of a fixed -wing aircraft and the capabilities of a

are completely different.

Combining those capabilities into a single airframe is particularly

How do you keep the aircraft under control while it shapeshifts in midair?

You have centers of gravity shifting, you're operating at different speeds.

so the characteristics of this aircraft are constantly changing.

And how do you stow a giant aircraft in the cramped spaces on board transport

ships?

So we have to be able to fit a high number of V -22s onto our amphibious

shipping, so it's important that we can fold it and fit it into tight spaces.

Operated by a crew of four Marines.

The Osprey accomplishes all this and more.

It's powered by a pair of Rolls -Royce engines that can propel it over 300

per hour.

A top speed more than 50 % greater than the planet's fastest helicopter.

The fighting Griffins are making their final preparations before taking to the

skies on today's training flight.

But this military exercise is only possible thanks to some of

the most groundbreaking aviation engineering the world has ever seen.

Responsible for a few world firsts, this revolutionary aircraft never fails to

amaze Osprey engineer Rod Olson. The Osprey is designed to take off like a

helicopter and fly like a fixed -wing aircraft.

It then lands like a helicopter as well.

The capabilities of a fixed -wing aircraft and the capabilities of a

are completely different.

Combining those capabilities into a single airframe is particularly

because you have to balance design requirements in order to achieve an

solution.

Mechanics and physics involved in solving the transition between

and airplane mode are particularly complex.

In order to solve this problem, engineers can look to history's

inspiration.

At the National Museum of the U .S. Air Force in Dayton, Ohio, aerospace

engineer Lynn Pickering has traveled to see a game -changing experimental

aircraft.

Oh my gosh, look at this thing.

It looks like it's straight out of a sci -fi film.

This is the Bell XVIII.

It's the only one left of its kind.

I would have to say this is one of the most exciting pieces of aviation

engineering that I've ever, ever seen.

Making its maiden flight in 1955, the XVIII is a true pioneer of aviation

engineering.

developed as part of a joint research program between the United States Air

Force and Army.

The experimental concepts introduced on the XV -3 laid the foundation that

helped make the Osprey possible.

This aircraft is actually the first attempt at tilt rotor technology.

And so what that means is that... This is in helicopter formation now, but when

the aircraft takes off, these blades rotate down into airplane mode. And then

when the aircraft needs to land again, they rotate back up, lands like a

helicopter.

These cleverly designed rotor blades allowed for a previously unprecedented

-air switch.

This is wild.

You'd think that.

Something like this should be impossible, that you take off like a

and then you transform kind of like a transformer, and then you're flying like

an airplane. So it's always been a bit of a holy grail for aviation engineers.

Leading the quest to realize this ambition were Bell designers Bob Lichten

Kenneth Wernicke.

I just think of how daunting this must have been to design something like this.

When you're trying to combine those two concepts into one airframe, you run into

a lot of issues.

And during a test flight in 1956, the XV -3 would demonstrate just how difficult

it is to perfect tilt rotor technology.

After the aircraft suffered extreme vibrations in midair, the pilot passed

causing the prototype to crash.

To solve this problem, engineers needed to go back to the drawing board.

So if we look at the wings, we can actually see one of the key design

after that first crash.

Their solution changed aviation forever and provided the groundwork for the V

-22 Osprey to rule the skies.

The technology demonstrated by the V -22 is really a long time coming and the

result of multiple decades of engineering.

The V -22 Osprey is a unique military aircraft with unrivaled capabilities.

Equipped with a pair of transformational tilt rotors, the Osprey can convert

between flight modes in just 12 seconds, allowing it to take off,

hover, and land like a helicopter, and fly at high speed and altitude like an

airplane.

To make this mighty machine possible, engineers needed to learn from the

and errors of their predecessors.

The Bell XV3 was the first aircraft to utilize tilt rotor technology, but their

test flight revealed a catastrophic vibration issue.

Having realized the flaw in their design, Bell's engineers set out to find

solution.

So if we look at the wings, we can actually see one of the key design

after that first crash.

They've added these struts in here to make these wings a lot stronger, and

that changed the whole frequency of the structure so that it no longer is going

to resonate with the tilt rotor tilting down.

And let me show you another aspect of the design change.

They actually changed from a three -blade design up here to two blades.

And they strengthened and shortened this pylon here on both sides to make

this stronger and decrease the vibrations.

And then inside this fairing here, we've actually got the electrical motor that

completes this 90 -degree arc in only 10 to 15 seconds. So very quickly, you're

able to go from helicopter mode to prop plane mode.

After incorporating its new design elements, the XV -3 successfully

problems, completing more than 100 full conversions of its tilt rotors between

1958 and 1962, making it the first aircraft to achieve a feat

engineers had long thought impossible.

The XV -3 might just be one of the most important pieces of aviation

engineering. It really took this concept of combining these two technologies,

which a lot of people thought was going to be impossible, and they proved that

it was possible.

Back on board the Osprey.

Today's expert flight crew is about to embark on their scheduled training

mission, which will test the aircraft's unique faculties.

Just like the XV -3, the Osprey uses its rotors in the upright position to take

off vertically.

then pivots them forward by 90 degrees, allowing the wings to generate lift,

completing the conversion to propeller plane in a little over 12 seconds.

Osprey engineer Rod Olson knows just what it takes to make this remarkable

possible. The secrets behind the incredible tilt rotor technology are

inside the structures on the aircraft's wingtips. known as nacelles.

So contained within the nacelle, there are several components that allow it to

operate. Primarily the engines, which are in this lower portion.

Then there are gearboxes further up, drivetrains, and ultimately the rotor

system here at the tip.

The pylon conversion actuator is responsible for actually moving the

and down.

It has dual redundancy, so in the event of a failure, the pylon conversion

actuator can actually allow the aircraft to land safely.

The pylon conversion actuator is a hydraulically powered telescopic ball

As the screw is rotated, it extends and rotates a lug that is

coupled to the nacelle, causing it to pivot from the vertical to horizontal

orientation.

When the screw is rotated in the opposite direction, the nacelle returns

vertical orientation.

If you look at the nacelle and the tiltrotor, you can see just how

the engineering is that went into this.

The tiltrotor technology employed on the Osprey is unique.

It does not use anywhere else in the world in an operational status.

Surprisingly, all it takes for Osprey pilots like Major Thomas Cecil to carry

out this incredible transformation is the push of a single switch.

The V -22 makes a transition from helicopter mode to airplane mode with

just the flick of the thumb.

On our TCL down here, we have a nacelle thumb wheel, and all we have to do is

push forward on the thumb wheel, and it begins to actuate the nacelle forward

towards airplane mode.

So when I push forward on the nacelle thumb wheel, it's going to actuate

conversion actuators on either wingtip and...

Through the conversion actuators, it'll modulate the nacelles down.

When we're ready to convert again and come back to VTOL, it's just a reverse

process. We'll pull back on the nacelle thumb wheel, and we revert back to

typical helicopter -style controls.

It's a groundbreaking achievement that's only possible thanks to the Osprey's

innovative aviation ancestors.

The technology demonstrated by the V -22 is really a long time coming and the

results of multiple decades of engineering.

And it all starts and is all built off other aircraft.

Back in the sky, 266 Squadron is underway on a training exercise

designed to simulate the challenges of a complex real -world military operation.

Copy, 80 feet, all calls in the back.

Roger, clear right.

With the Marines regularly deployed in the planet's most hostile locations,

essential that the Osprey can get them there safely.

And that means being able to land

in low -visibility conditions.

We have to be able to take this aircraft into any environment.

And because of the amount of downwash that we create, we have to be ready for

dust, sand, snow, anything.

And that's going to reduce our visibility when coming into land.

Losing visibility during a landing is extremely dangerous. If you can imagine

pulling into your driveway with your eyes closed while you're driving your

you just trust yourself to just stop before you crash into your garage door.

But in this case, we have maybe up to 25, 27 people's lives on the line

and very expensive equipment.

If we were to crash an aircraft, that right there is mission failure.

So it's very important that we're able to take off and land in a reduced

visibility environment.

Incredibly, engineers have come up with a solution that allows the Osprey to

operate in zero visibility, helping pilots avoid disaster.

We have a couple different ways that we can do this.

One is through an automated approach, which is pre -built into our flight plan

to assist the pilot to make a safe landing.

We're really talking about the very final stages before landing, and this is

where we're going to lose our visibility outside.

By using GPS technology to identify a suitable landing location, the Osprey

control its drift and rate of descent to safely touch down without any input

from the pilot.

And the aircraft's high -tech instrumentation can also be used to

landing when loss of visibility is not expected.

We can also use automation on the fly, and we engage that utilizing the flight

director panel.

The primary piece that we're looking at here is the hover coupler, and utilizing

this is going to give us varying degrees of lateral control assistance to

minimize drift. It's also going to help us slow the aircraft down and give us a

controlled rate of descent.

When we're ready to land, we can just engage basically the altitude control,

then we control the altitude and rate of descent.

It's an amazing solution that's essential to allow the Osprey to land in

world's most hostile locations in zero visibility.

It's just not possible without this system and without these displays that

have. The team has devised a one -of -a -kind multimodal aircraft capable of an

amazing transformation, but engineers now face the problem of how to keep it

stable while it morphs in midair.

There's a lot of challenges with operating in conversion mode.

In order to land, we have to slow down.

This involves converting.

And as we do, this changes the configuration of the aircraft and brings

different handling characteristics into play.

To help keep the Osprey stable through this unique conversion process,

must look to the pioneers of the past.

All right, you ready to go?

Yeah, man, let's go fly it.

Engineer Dan Dickrell has traveled to the heart of Georgia.

Oh, I can't wait to see this.

This is going to be awesome.

To discover a plane with a trailblazing design.

Dang, look at that.

What a beautiful and shiny aircraft.

It's a Lockheed Electra 12. It's a classic example of Art Deco era of

There's only about 10 of these left in the world, and today I get to fly one.

First taking flight in 1936, the Lockheed Model 12 Electra Jr.

is a pioneer of passenger aviation.

And it holds the key to keeping the V -22 Osprey stable as it transitions

between helicopter and airplane in midair.

All right, seven lakes in traffic, Lockheed, departing runway 18, seven

Building on the success of the Model 10 that went into production two years

earlier, the Electra family of aircraft was famous for its forward -thinking all

-metal construction and the early adoption of twin engines.

All right, you ready to go?

Yeah, man, let's go flying.

And as Dan is about to discover, the Electra is an aircraft that's remarkably

easy to handle.

But in the early days of the Electra's

development, a flaw was discovered in one of its key components, a defect that

threatened to keep the airplane grounded.

aircraft control one of the primary control services is the rudder the tail

that's the part that allows the plane to yaw in the sky go left and right so

much like the steering wheel in a car allows the car to turn left and right i

have two pedals on the floor that i have my feet on and if i press the left

rudder pedal in strongly there we go it turns to the left and if i press

my right pedal in

We go to the right a little bit. There we go.

Those are the basics.

Initially designed with a single tail positioned in the center of the

wind tunnel tests showed the Electra was vulnerable to instability in flight.

This is obviously a problem, especially if you're trying to design a passenger

plane. So the engineers knew that they had to solve this in order for this

aircraft to be successful.

The solution came from an unexpected source,

Clarence Kelly Johnson, a student working on the Electra program.

So Johnson realized the problem with the prototype stability came down to the

single tail.

And his solution was this, a twin tail design.

This simple design tweak was a game changer for the Electra, and it solved

prototype stability problems for good.

The reason why the twin tail works as well as it does comes down to placement.

If you can see, the propeller on this side of the aircraft is almost in line

with the tail, right? The reason why that helps is because the slipstream

coming off of this propeller is in a position where it can interact with the

control service, this rudder. And remember, a rudder helps the airplane

or right in the air.

in situations where there's low speed either on takeoff or landing the ability

of this control service to safely move the airplane around is most important

that's one of the upsides of this design versus a single tail single tail can't

take advantage of that alignment and that increased airflow and so that's why

this twin tail works as well as it does additionally since there's two tails

there's twice the area twice the area you have much more control authority to

maneuver this plane in the air. It's a brilliant solution.

Over 85 years after Johnson introduced the twin tail on the Electra, the

pilots utilized the same innovative concept.

The twin tail is what gives us aircraft that directional stability when we're

operating in airplane mode.

On each vertical stabilizer, it has a rudder. Those rudders are both actuated

utilizing the pedals on the floor of the cockpit.

And we use that to control and make directional control inputs.

Also in between our two vertical stabilizers, we have the horizontal

with the elevator, which is this giant kind of whale tail, which you see. And

that gives us longitudinal control.

As with the Electra, the Osprey's use of this tail technology is key for

ensuring a smooth flight experience.

We have to have a certain amount of stability.

Without the twin tails, those aircraft would be much, much harder to fly.

And this stabilizing innovation is also involved in steadying the aircraft

through its challenging conversion process.

The twin tail makes it possible for this aircraft to transition between airplane

and VTOL.

When we're an airplane, all of our controls are... actuated similar to any

airplane. And then as we move towards VTOL, everything is made through the

similar control inputs to what you would see with a helicopter.

In between, it's a combination of the two.

And converting to helicopter mode.

So as we transition from airplane -type control inputs towards helicopter -type

control inputs, it's a blend utilizing the tail, whether it be the elevator,

rudders, combined with inputs through the prop rotors to achieve for the

output and control that we require.

It's an ingenious modern use of this historic technology that helps give the

Osprey its one -of -a -kind capabilities.

But in order to accomplish its global missions, it needs to be transported

distances inside the restricted space onboard an aircraft carrier.

We have to be able to fit a high number of V -22s onto our amphibious shipping,

so it's important that we can fold it down and fit it into tight spaces.

To achieve this, engineers can turn to history's innovators for inspiration.

What's amazing to me is how much still is relevant today. It's remarkable.

To transport troops and cargo anywhere in the world.

Engineers have created a shape -shifting military

flying machine.

Part helicopter and part airplane.

The V -22 Osprey is the ultimate aircraft.

Fitted with three fuel tanks in the fuselage.

And two more integrated in the wings.

The Osprey can hold close to 1 ,500 gallons of fuel.

Around 75 times more than a family car.

And enough to fly non -stop from Miami to Philadelphia.

In the skies above North Carolina.

Tail right to land on the Delta Taxiway.

The 266 Squadron flight crew is returning to New River Air Station,

completed a successful training flight.

Front, three down and locked.

Just seen, I got Blackburn on top of you. I got Blackburn.

Copy.

But for the Osprey to carry out its worldwide missions, the aircraft must be

able to travel distances far beyond its flying range.

So the Marine Corps has our nation's force in readiness.

It's important that we have an aircraft that can operate in any place around the

globe. So it's extremely important that the V -22 be able to fit and operate off

of existing amphibious shipping.

We have to be able to fit a high number of V -22s onto our amphibious shipping

that has limited hangar space. So it's important that we can fit it into tight

spaces.

But squeezing an aircraft measuring 84 feet wide into a restricted footprint.

presents a potentially impossible problem.

The size constraints the Osprey has to fit in are approximately 20 feet wide by

20 feet tall by about 63 feet long.

It's a significant design challenge to combine all of the details of the Osprey

into the small footprint while still meeting critical flight characteristics.

To find a solution, engineers must seek inspiration from the pioneers of the

past.

In San Diego.

Oh my gosh, this place is absolutely massive.

Helicopter pilot Micah Muthio is on board an iconic aircraft carrier, the

Midway.

It's incredible to be standing here. This is four acres of floating aviation

history. Can you imagine what this was like back when active? The sound of the

jets, the spinning of the blades, all that activity.

Commissioned in 1945,

the Midway was once the largest ship in the world.

As an aviation nerd, it's cool to see all the aircraft, but putting them in

context of an actual aircraft carrier really brings it to life.

But even the Midway's hangar space was limited.

And aircraft with large wingspans or propeller blades are not easily

transported.

The Navy needed a way to maximize the number of aircraft per carrier.

Thankfully, in 1943, engineer Michael Boyvid helped design a helicopter

with an ingenious solution that would redefine how aircraft are transported.

Look at this thing. It's amazing.

This is the Sikorsky H5, also known as the Dragonfly.

From a pilot's perspective, when I look at the cockpit, I just think the field

of view is incredible. You can just see in all directions.

But the view is not the H5's greatest accomplishment.

What's amazing to me is how much... still is relevant today.

There's so many components on here that just worked and we've stuck with them.

And the innovative engineering behind this groundbreaking aircraft is exactly

what the V -22 Osprey team has been looking for.

To me, this folding mechanism is a real game changer. That's really incredible.

The B -22 Osprey is one of the most remarkable machines on the planet.

Built to carry troops and cargo at high speed over long distances and into hard

-to -reach locations, it can achieve the seemingly impossible by

transforming itself from helicopter to airplane in midair.

But each individual aircraft has a huge footprint.

making them difficult to transport and store.

To solve this problem and maximize the Osprey's potential, engineers are

to the Sikorsky H -5, a pioneering helicopter that inspired the team behind

Osprey.

So the H -5 was special because it was very high performance, flew up to 21

feet, which is something I've never done in a helicopter.

What's amazing to me is how much...

still is relevant today.

There are so many components on here that just worked, and we've stuck with

them. It's remarkable.

Built to offer the armed forces a helicopter that could carry greater

fly longer, faster, and higher than previously possible, the H -5's

performance allowed it to become the first helicopter to operate in the

Antarctic.

But arguably the most important of this exceptional aircraft's features was its

revolutionary rotor blades.

Look at these blades. They take up so much space. It's like a big ring all the

way around the helicopter.

That's really inefficient use of space, especially if you have the confines of

an aircraft carrier.

We're in a hangar right here. There's not a lot of space.

the rotor system.

It's roughly 50 feet in diameter, and if you get two of these side by side,

that's 100 feet of space that you're taking up just because of the rotor

But as Micah is about to discover with help from the carrier's crew, these

blades can perform an innovative feature to solve the problem.

So the first thing you're taking out, that's the pitch link bolt. The pitch

link. It controls the pitch of the blade.

Okay. Now what I'm going to do, I'm going to rotate it. So basically I'm

to change the pitch on the blade.

Okay. We're going down.

Going down. Now he's going to pull the wing or the blade attach bolt out so

we can swing the blade. Gotcha. And that lets the whole blade rotate back. Yes.

Okay.

Here's the moment where I hope not to drop it. Okay.

Oh, and it just rotates back like that. Okay.

I think it's pretty easy.

Okay, just walking it back.

Okay.

After removing just two bolts, the blades are ready to fold, allowing the

be totally transformed in a little over a minute.

Okay, coming down a little bit.

So we're going to drop the blade down. Slide it up into the cradle. Slide it

And then two bolts back here for the little clamp, and good to go.

When they started bringing the H -5 onto ships, they would just fold them back

like this, and this is how you store them.

Yeah, except for back then you had two 20 -year -old sailors doing it.

A couple of old guys like that.

And after repeating the same process on the opposite side of the aircraft, the H

-5 can complete a feat that had previously been impossible for a

By fully folding its blade, the H5 significantly shrinks its footprint.

All right, now what I'm going to do is I'm going to rotate it a little farther

to where I can drop it out.

And coming down a little bit. Okay.

I'm not going to say there's a lot of pressure here, but this is a very old

helicopter, and the guy holding the blade, don't want to break it.

Got that.

It is remarkable, though, that just a few seconds ago this thing was ready to

fly. Yes. Well, ish.

And now here we are.

Okay.

That was suspiciously easy.

I think I'm ready to join the crew, guys.

I'm ready to join your squad.

Voyvich's transformative blade fold design helped revolutionize the

military aircraft, dramatically reducing the space required to carry a

helicopter. What's incredible to me is that we've gone from 50 feet wide to 5

feet wide in about a minute.

And today, blade folding is still an essential feature on an array of modern

aircraft, proving the importance of Boyvitt's ingenious invention.

To me, this folding mechanism is a real game -changer, making it possible to fly

a helicopter from a ship -borne environment. That's really incredible.

To complete the V -22 Osprey and make one of the most versatile aircraft in

history, engineers will take Boivitt's brilliant solution.

It's amazing to see such a massive aircraft turn into such a small

like this. And make it all their own.

This is the world's first complete blade -folded wing -sew system.

Today in North Carolina, the V -22 Osprey's engineers have taken Michael

Boivitt's blade -fold innovation.

and modernized it to achieve a new feat in aviation.

This is the world's first complete blade fold and wing sew system.

There are other platforms that use a portion of blade fold or a portion of

sew, but in no cases is there a complete process all in one aircraft.

Unlike the manual fold method designed for the H -5,

The Osprey's unique system is entirely automated.

At the start of the blade fold sequence, the squash plate actuators that control

the rotor head move to the fully retracted position.

This causes the blades to hit vertical.

The aircraft then folds the outer two blades so that they join the blade

currently over the wing.

Once that's complete, the cells begin to rotate down into the horizontal

position, and in doing so, the wing also begins to rotate.

Once the wing has completed its rotation to sit parallel with the airframe, the

operation is complete, taking approximately 90 seconds to shrink the

84 feet wide to less than 19 feet wide.

The execution of the blade full wings is like a party trick.

It's amazing to see such a massive aircraft turn into such a small

like this.

It's a remarkable transformation that's vital to the Osprey's functionality.

allowing the aircraft to operate from the confines of an aircraft carrier.

This

feature,

along with the V -22 Osprey's other unique capabilities, make this

aircraft one of the most advanced machines ever to navigate the sky.

Every day I look at the Osprey, I can't believe how amazing it looks.

The engineering that was involved to design this aircraft blows me away.

It's an extreme honor and privilege for me to be part of this Osprey team, not

just for this fantastic aircraft, but also to work with those men and women

keep this aircraft flying.

By looking to the pioneers of the past for inspiration.

Adapting their ideas.

Building on their designs.

and triumphing over enormous challenges.

This is a game -changing aircraft for the Marines. It accomplishes things that

no other aircraft can accomplish.

It's a real -life transforming.

The Ospreys team has created a revolutionary piece of aviation

and succeeded in making the impossible possible.

It wasn't long ago that people thought it impossible to combine both helicopter

and airplane capabilities.

We've redefined what's possible on the battlefield.
