This is the mother of them all.
It is the deepest of them all, so we've got a lot on the line.
We're going to be assaulting the Challenger Deep
with more technology and capability
than anyone has ever done in history.
You realise how deep we are, right?
Oh, my word. Look at that!
It's going up.
This is really high. Whoa! Up, up, up, up, up, up, up.
What the hell is that?
I've got a big battery fault.
Surface, LF has lost power.
Humankind has explored every continent on earth.
We've climbed its tallest mountains...
..and even journeyed into space.
Thank you, Mr President.
There's a vast swath of our own planet
that has remained a mystery.
The deep ocean.
Stretching down over 35,000',
into crushing pressures, it's been near-impossible to reach.
Until now.
New engineering breakthroughs are driving
an audacious global mission to dive to the deepest points
of all the five oceans for the first time in history.
These pioneers will push technology to the limit...
What the hell was that? We have a leak in the hatch. Oh, my God.
..to open up this final frontier as never before.
To try and, like, mentally put yourself
at the bottom is just mind-blowing.
Mapping hidden landscapes.
Discovering unknown life forms.
There's something there. And unlocking the secrets
of how life in the extreme deep ocean affects our entire planet.
Ex-naval commander Victor Vescovo is now getting ready
to face the ultimate challenge of this expedition.
The deepest dive on our planet.
Roger that, you are free to dive.
So far, he's travelled 20,000 miles,
halfway across the world,
and completed three record-breaking dives.
I just want to say thank you all, for getting us to this point.
It's been four years since we first started thinking
about this overall mission.
But now he will be pushed to the limit
by the largest and deepest of the earth's oceans.
The Pacific.
I mean, this is the mightiest ocean of them all.
This is a third of the surface of our planet.
The Pacific Ocean is different than all the others
in that it has the oldest sea floor in the ocean.
It's just a much deeper, much older ocean.
It is also home to the deepest place on earth,
the Mariana Trench.
From a very young age, I loved just looking at atlases.
One of the most prominent features in any atlas
is the deepest point in the world,
which is the Mariana Trench.
This deep, dark place,
of course, it captured my imagination.
It's 8,000' deeper than any dive Victor's attempted before,
and it will subject the sub to enormous pressure.
Just come up on the A frame.
Let me know when we're clear for straps.
We're clear for straps.
It's an extreme an environment as we have on planet earth.
This is the major league.
You know, this is as difficult, as technically challenging
as submersible driving gets on planet earth.
The bottom of the Mariana Trench
has only been visited by three people,
and one of them is on board.
Cool. OK, good. Thank you, guys.
Captain Don Walsh.
In 1960, he and a fellow deep-sea explorer
took an experimental craft
to the uncharted depths of our planet.
I never had any fear.
Why have fear? What are you going to do about it?
You're committed.
You're gonna go down there as far as you can.
If something doesn't work, too bad.
There's nothing we could do about it.
Don is getting a tour of the sub
and discovering that much has changed since his day.
Is there a panic button?
So, you're the professional pilot... Yes.
You crap out, the guy on the right - Yes.
..is perfectly good. There is.
It's called the Watchdog system.
Every time you do a comms check,
it resets the Watchdog system.
Because Victor is diving by himself,
if something happened, he became incapacitated,
we wanted a system that would bring him back to the surface.
That's that system. It's pretty special for me.
I feel like a kid in a candy store.
I don't have any duties here except,
you know, show up for meals and smile a lot.
I'm a ceremonial object at my age
but, still, it's not given to many to, first of all,
pioneer something in their lifetime.
Do something for the first time, then, secondly,
to see it play out six decades later.
What is state-of-the-art...? It's a gift.
In 2012, Don witnessed the solo dive of Hollywood director
and deep-sea explorer James Cameron, who recorded a depth
at the bottom of the Mariana Trench 10' shy of Don's record.
Hey, Victor. Hi, Jim. How are you? Good, good.
It's great sitting next to the first person
to go down to the Challenger Deep.
It's wonderful to be able to talk to the second person.
Hopefully we can pass the baton. That's great.
You've really kicked the ball down the field
in terms of the technology.
The only other piece of advice I would give is
give yourself a moment to stop and just look out the window.
Just think about where you are and what it means.
That's great, Jim. I appreciate that.
But now Victor is on a mission
to find a spot even deeper than Don Walsh and James Cameron,
and break a record that has stood for 60 years.
We have one of the best sonars in the world right now.
We're going to produce
the most accurate map of the Mariana Trench
that's ever been done before.
The deepest section of the Mariana Trench is in a hollow
known as the Challenger Deep.
But the team also want to take on a deep ocean exploratory dive
140 miles east in the Sirena Deep,
where no submersible has ever been before.
So, the deepest part is right in here.
Nobody's been down there.
The team will be on the hunt for vital new scientific data
that may help find alien life elsewhere in our solar system.
Because there are frozen moons, like Europa orbiting Jupiter,
that NASA believes could hold life.
Beneath the surface ice, deep oceans might nurture organisms
able to exist in environments as extreme as the Mariana Trench.
NASA's search for life efforts
are looking for the limits of life.
They are interested in looking at
the deep trenches to see if
microbes can live in these
most extreme environments on the planet.
If they can find colonies of bacteria in the Mariana Trench,
then extreme forms of life could also exist
in the oceans of those alien moons.
The general conception I have for this dive is that
this is very much a science-focused dive.
One thing that I am concerned about is recovering the samples.
First priority is a rock with stuff on it. Fingers crossed.
Just be vigilant as you're approaching the bottom.
That depth sounder, once it starts picking up
and as you know, Victor, is giving you reliable data,
pay attention to it, you can't ignore it.
I don't know if there's pinnacles or haystacks.
Who knows what we'll find? We're going to leave that one down.
Even though the dive is not the deepest in the Mariana Trench,
at 35,000', it will put the sub's engineering under massive strain.
It's a substantial pressure, so we've got a lot on the line.
We've basically got all the poker
chips in the centre of the table.
Chief scientist Alan Jamieson
is joining Victor on this pioneering dive.
Welcome back, sir. Hello.
LF, LF. LF. LF.
We're gonna go for release here.
We're gonna get the sub off the hook.
Perfect.
And we are currently about 900 metres from the drop zone.
OK, roger that.
We can tow him for a couple of minutes, no worries.
12-14 minutes till we are ready to let him go.
To dive, Victor will pump water into empty ballast tanks
at the top of the sub.
But now the waves are picking up and flooding them early.
75 to go.
They're spending a lot of time under the water.
The tanks are going to be filling all the time.
With that much weight on the sub, that goes down quick.
50 metres to go.
That's gotta be it. We can disconnect now.
Release! Release!
It's tied off. Get that tow line.
Come on, Tim, get her loose.
Release!
The tanks have filled up. She's diving.
Swimmer Tim's got just seconds to release the towline
and must avoid getting entangled and dragged to his death.
Release! Release! Release!
Come on, Tim, get her loose.
As I'm taking the handrails off,
I could feel the sub going out from underneath me.
In a panic, I tried to get out of there as quick as possible,
to make sure I wasn't tangled up in anything.
On their way down, Victor and Alan pass through the top layer
of the ocean, called the Sunlight Zone.
Home in the Pacific to one of the nature's greatest survivors...
..the nautilus.
It's remained virtually unchanged for half a billion years.
As the sub goes deeper, the light dwindles,
and they enter the Twilight Zone.
Here, out of the darkness,
emerges one of the wonders of the deep ocean.
Creatures that generate their own light.
Wow, look at the bioluminescence.
Oh, that's so cool. How bright is that? Yeah.
Bioluminescence is the most commonly-used communication
on planet earth, in terms of the number of species that use it.
In the Pacific, the Twilight Zone holds other
extraordinary creatures adapted to live in the gloom.
Like the Cock-eyed Squid.
Its larger left eye can pick out
camouflaged prey in the waters above.
While its smaller right eye points downwards
to spy any predators lurking below.
The sub is now passing 3,000'.
Beyond here, a US nuclear sub would be crushed like a tin can.
This is the Midnight Zone,
where some of the most bizarre animals on the planet
are still being discovered.
This is a gulper eel, which can detach its jaw
and inflate its body to swallow much larger prey.
Somewhere between 3,000 and 6,000 metres,
just as the pressure decreases the size of the sphere,
it tightens, and it happens suddenly.
It makes a little rapping noise on the capsule,
it's a little unnerving.
We've been in the submersible now for three hours -
Just over three hours. ..and nine minutes.
The sub is now in the deepest ocean region of all,
the Hadal Zone.
And, finally, their goal is in sight.
I can see it.
See it slowly getting lighter?
11 metres off the bottom, we should see it very shortly.
Four metres off.
That's one metre off the bottom.
That's the bottom of the Sirena Deep.
It's incredible, isn't it?
Surface, LF.
Surface, life support good at bottom.
Repeat, at bottom.
By the way, congratulations.
First man to descend to the Sirena Deep. As are you.
The sub is now under some of the most extreme pressures on earth.
Victor and Alan are the first humans to see
this unexplored landscape.
Now they need to look for communities of bacteria,
the kind of extreme life
that NASA might find beyond our planet.
Finding a microbe in the bottom
of the Mariana Trench is important to me.
Deep at the bottom of the ocean,
you don't have access
to sunlight.
These organisms have to use some other source of energy
other than sunlight.
Some bacteria have developed to feed on chemicals
seeping from the earth's crust,
but none have been found in these extreme depths.
What should I be looking for?
You're looking for bacterial mats of distinct colour.
What do they look like? Some are white.
Some of them are really strikingly orange and yellow.
OK, your eyes are outside, I'm on inside. Yeah.
Been down here two hours, 15 minutes.
Already? Yeah.
How long do we have?
We are below 50% below on the batteries.
All right, stop, stop, stop.
What is that? Whoa!
Up, up, up, up, up, up.
What on earth was that?
Is that a bacterial mat?
Look at that. Look! Look! Look!
Yep, that's it!
See the yellow?
The yellow growth on the rocks is in fact millions of bacteria
feeding on chemicals seeping from the earth's crust.
And it's the deepest ever observed.
High five.
I knew patience would reward us.
The team have visual evidence of the kind of extreme life
that could exist in deep oceans elsewhere in our solar system.
Now they need to bring back a first-ever physical sample.
The current is pushing us to the right.
Look, it's heading... Whoa!
Now a strong current is making this delicate task
near impossible. Flying a submarine in a current
with one hand and trying to get a rock with a manipulator...
This is really hard.
Oh, my God, my heart is going faster.
Whoa!
Just give it one more try.
I got a rock!
I can't believe I got a rock.
It fell apart! Damn it.
What was that?
Our batteries. We've been here three hours.
That's it. I tried. OK.
All right, I'll drop weights.
Surfacing weight, we're on our way.
Sorry I didn't get a rock for you, Doctor.
I tried like hell.
Surface, surface, LF, how do you read?
The team failed to obtain a rock sample but,
as the sub comes back onboard, the crew make a surprising discovery.
This is so cool you guys found this rock in here.
Can you show me where?
The rock was basically just down in the bracket there.
It was sitting on that flat spot. Ah, yeah. Yeah. That makes sense.
The mud got us thinking, "Let's keep an eye out."
This is great. What a find.
This is the first rock that has been recovered
in the Sirena Deep.
Microscopic analysis of the rock surface
shows intricate bacterial growth.
For us as astrobiologists, to know that there is life
deep in the ocean, gives us confidence
when we start to look at other places in our solar system.
That there are organisms that can survive on another planet
without sunlight, and live under very high pressures.
At least we know it's possible and it's worth going looking.
Wait. Hold on a minute. I'm going to grab that line.
Now the team discover a problem that could jeopardise
any further dives into the Mariana Trench.
One of the three navigational probes, called "landers",
is missing.
Alan said that the one of them is still not on its way up.
That means it must be stuck.
Lander's stuck in the mud down there.
Bad news, man.
You know what you've got to do, don't you?
Go back and get it? Yeah.
To save the mission,
they must risk an unprecedented deep-sea rescue.
If we are able to actually rendezvous with a dead target...
We are attempting the deepest salvage operation
that's ever been attempted by man, so no pressure.
The big challenge is to find the lander
that has now ran out of battery,
so it's not able to signal to us where it is.
Once we find it with the sub,
the sub will need to either work it loose
by using the manipulator to free it.
If it needs to remove the weight from the bottom it will need
to put the manipulator arm in underneath and cut the wire
that's attaching the weight to the lander itself.
At the helm of this risky operation,
Victor puts one of the most experienced sub pilots
in the world, the builder of the sub itself, Patrick Lahey.
If we find it, we are going to try and get it off the bottom.
Whatever it takes, we'll release it.
But grappling with the lost lander holds a terrifying danger,
of the sub itself getting trapped irretrievably on the seabed.
The thing you worry about is entanglement.
You have to be vigilant as a pilot.
You have to be to paying attention to your surroundings.
All right, McGee. Get it done, buddy.
Get it done. Get it done. Right.
Bring us home safe, buddy. Thank you.
Thank you, Frank. OK. I'm getting ready.
See you later.
Accompanying Patrick is deep-ocean submarine specialist
Jonathan Struwe.
It's really dark and deep and difficult down there to navigate.
I hope they find Skaff. What an amazing achievement that would be.
Let's have a good dive. Let's have a good dive.
You are a long way from home down there.
And you feel it, I tell you.
Let's launch the sonar.
I am going to go ahead, I'm going to increase the scanning speed.
Once on the bottom, they start the search for the lost lander,
codenamed Skaff. Oh, yeah. That's-That's something.
We are two metres off the bottom.
We'll get you, Skaff. Yeah.
They use the sub's sonar to ping the surrounding landscape
in the hope of a return echo.
Bingo. Now it should be in your window.
Just a second, it'll be in your window.
That... You can see it!
Oh, yeah, here we go.
Skaff. There we are.
OK, we're on it.
Yeah, it's ahead of us.
Yeah, dead ahead of us. It is dead ahead of us.
Yeah, I'm getting right over there, get the lights on it.
There we are.
Having landed at an awkward angle,
one corner of its base is wedged in the sediment.
Jonathan must now work the robotic arm to release it.
This is the most dangerous part of the operation.
Ah, . What is going on here?
Index again and then try and straighten out.
Try, try, try doing that.
I can't, for some reason.
Ah!
OK, allow me just to come ahead. I'm going to push you.
I am going to push the lander.
If the arm gets entangled with the lander,
and the emergency arm-release fails,
they could be trapped beyond any hope of rescue.
Back up just a little bit.
Get into the right position.
What was that?
Patrick and Jonathan are attempting a daring rescue mission
seven miles under water.
Get into the right position.
One wrong move and the sub could get snagged on the trapped lander.
He's going up!
He's on his way!
Aaah!
Patrick!
Woo!
Surface, LF, the lander has released.
This is the deepest maritime salvage operation ever attempted.
And to say that we had a marine lander trapped on the bottom,
then sent a two-person submersible
to the bottom, found it, and released it,
is simply a technological tour de force.
It's extraordinary. I am so proud of the entire team.
With all three landers on board,
the crew is now getting ready for the deepest dive on the planet.
And the scanning team has made a ground-breaking new discovery.
Their high-resolution data reveals a location on this planet
that's deeper than any found before.
We estimate to be 10,920.
Plus or minus 15 to 20 metres.
At nearly 36,000' deep,
it's a staggering 117 times the height of the Statue of Liberty.
If Victor is successful in his mission,
he will become the deepest-diving man in history.
And break the record set over 50 years ago
by pioneering deep-ocean explorer Don Walsh.
This is a 3-D imagery of the Challenger Deep,
and here we are arriving at the western pool where you dove.
Over the central pool and then the yellow dot being
what we think is now the deepest point.
So, you have the advantage of knowing where you are. We didn't.
You know how we did the depth finding? No! Tell me.
I'm not really familiar. We used 1lb blocks of TNT.
You threw explosives into the water? Yeah.
They came like that, they were all cast, hole in the top,
put the detonator in there and light the fuse.
All the sailors volunteered to fling these things off the back.
Because the...think about it.
The transducer for the fathometer is perfectly adequate.
So, you blast off a piece of TNT. Start the stopwatch -
You would start the stopwatch, count the time,
then you would use what speed, to figure it out? Nothing.
Seven seconds is deeper than five.
OK Very empirical and no GPS,
and so we're kind of guessing, by gosh, and we're just lucky.
Right. It's a skill. We're so fortunate, we're in a place
in the world where we have probably ten-plus GPS satellites
to tell us exactly where we were.
I guess one question that I had is, when you were diving in your area,
the Trieste went down, and then obviously we've heard the story
where it got very milky-white and you couldn't see much.
There wasn't a lot of manoeuvrability for the Trieste
to get out the clouds or go to any of the other areas? Very limited.
Very limited, it was such a big craft.
In metres, in terms of where we could move
and the amount of battery power we had.
We used silver zinc batteries, that were all inside the cabin
and they were dangerous little things.
I can imagine your vessel was almost ten times the size of mine
and you had less power and so we're fortunate that
we're going to be able to go down and hopefully cruise around for
four, five hours. I'd characterise ours as a freight balloon.
Yours is really a submersible.
I did have fun, I think we learned a few things and when we came,
after we surfaced, Jacques and I were sitting top-side
waiting for a boat to pick us up.
So how long before somebody else gets there?
We finally agreed, after some discussion, two years.
In fact, it was half a century.
We're going to be assaulting the Challenger Deep
with more technology and more capability
than anyone has ever done in history.
We have the most advanced sonar in the world and we have a submarine
with a two-person titanium sphere that can do multiple dives.
No-one has had this before.
One, two, three.
This will be the sub's ultimate test.
The Challenger Deep here in the Mariana Trench
is the Mount Everest of deep-ocean diving.
The pressure is 16,000 psi.
The viewports, they compress almost a quarter of an inch
under that intense pressure. Ready for Victor.
500m from the site.
It's 3½ to four hours down and up.
Have a great dive, Victor.
So it stresses every part of the submersible.
Good luck to us all.
What's really worrying is just that something might not work.
If something serious goes wrong,
Victor is on his own, where no other craft can possibly reach him.
Sub's clear!
All comes down to this.
After four years of planning, building, testing, diving,
this is the big one.
Fantastic.
Have a good one, Victor.
Thank you. See you all on the other side.
Let's get my oxygen going here.
To keep Victor alive deep under the water,
the sub is equipped with enough oxygen to last for four days,
but the carbon dioxide Victor exhales could be lethal.
So two high-tech devices called 'scrubbers',
packed with absorbent materials, work relentlessly
to keep the carbon dioxide below dangerous limits.
Surface, LF, present depth, 833.
Heading 045.
Life support good.
Roger, LF. Understand.
Life support good. We have you loud and clear, Victor.
You can hear the outside of the sub creaking just a little bit
as it just kind of settles in.
Every 60 seconds, the pressure on the sub increases by 400 tonnes,
the equivalent of one jumbo jet added on top of it every minute.
Victor is aiming for a lander,
located in the deepest part of the trench.
He will then ping the other two
to determine his exact position on the seabed.
My three companion robots are probably on the bottom now.
Patrick, we've got an issue.
Lander is on the way up.
The release mechanism on one of the landers has triggered early
and it is now hurtling up under the sub.
Captain be advised, we appear to have a situation.
The lander has left the bottom, unexpectedly.
At this time, just about 400m below Victor and on its way up.
That's weird, the lander is getting closer to me.
Wrong reading?
Is there something wrong with this modem?
LF. LF.
LF. Roger, go ahead.
Be advised, lander has left bottom.
Has left bottom.
Oh, .
There is a collision risk.
I mean, I'm going down right on top of it.
Hope it doesn't hit me.
If there's a collision,
it could rupture mission-critical components of the sub.
They are not even 200 metres apart now.
150 metres apart.
They're 100 metres apart.
Within 50 metres.
On his way down to the deepest place on earth,
Victor is in danger of crashing into one of his own robotic landers,
now heading up beneath the sub.
If Victor collides with the lander,
it could be the end of the mission.
I've always worried about mid-air collisions as a pilot,
but I never thought I could have that deep in the Mariana Trench.
Within 50 metres.
I'm certainly not going to be jamming thrusters down.
I don't want to run into him.
They're probably very close to one another.
It's above him.
Yep, looks like it has passed me.
Strange things happen down at this depth.
Wow! Seeing 10,000 metres is pretty interesting.
That's a big number.
Can't help but be a little bit nervous.
The sub is now under the greatest pressure in our oceans,
equivalent to having the largest aircraft carrier in the world
sat on top of it.
Altimeter is at 10837.
Looking out the portal just to make sure that
I don't slam into the bottom here.
34 metres to go. Should start coming into view.
Come on.
So close.
18 metres.
I can see the bottom on my display.
There's the brown of the bottom.
Touchdown.
There is the bottom of the entire ocean.
Surface, LF, at bottom.
Congratulations, Victor. Congratulations.
Congratulations to you all.
Victor is now 35,843' below the surface,
deeper than anyone else before him.
Beginning exploration of the bottom.
Outstanding. What a moment.
Wow, it's so soft.
In some respects, this is such an alien environment.
11,000 metres down, 16,000 psi, no light.
This is almost like an alien world.
Oh, whoa, whoa. What's that guy?
Whoa, whoa. We've got to go back and check that out.
That looked like something really interesting.
Who are you, little guy?
What in the hell are you? You are like a jellyfish snake.
This sea cucumber uses its transparent tube feet
to forage for food in these crushing depths.
Definitely some life down here.
I saw it with my own eyes.
During their operations below 13,000' in the Mariana Trench,
the science team has gathered footage of even stranger animals.
Look at that. That is cool.
This fish is a cusk eel.
What makes this one really interesting
is that it has a transparent head, made of a gel-like substance.
It's almost certainly a new species.
No, that's not a fish.
What the hell is that?
This animal that is drifting past the camera
is a colony or collection of lots of little small animals.
It's kind of like a jellyfish, but there is lots of,
if you imagine thousands of little jellyfish all holding together,
and we call that a siphonophore.
Oh, that's a really good shot.
I would say that's the best video of a snailfish we've ever got.
The Mariana snailfish is quite an iconic fish.
These fish are right on the absolute limit
of what all fish in the world can cope with.
If they were to go any deeper than where we have seen them,
their cells would start to implode.
It is a rare glimpse of the elusive creatures of the deep,
but soon Victor makes a more disturbing discovery.
What the hell is that?
I saw something that looked like a triangle.
Nature doesn't do straight edges, they don't do straight lines,
and I saw something that looked a piece of refuse.
Close examination reveals what appears to be a letter "S",
evidence of the unstoppable impact of human pollution.
It's unfortunate that even there at the very bottom of the ocean,
that there is, you know, contamination of some kind.
Victor has broken a record,
but extreme conditions are taking their toll.
I've been here for four hours.
We're running out of power.
Challenger Deep.
Let's go home.
Surface weight release. Here we go.
Like a moon launch.
What was that? That's a new one.
Well, that ain't good.
It looks like we've got a big battery fault, yeah.
I wonder if I hit something on the bottom that caused an issue.
That's great.
Now everything is black in here.
My heart rate is up a little bit.
Surface, LF has lost power,
is on emergency battery power only.
Do not have depth indication.
Roger, understand, we will track you from the surface.
Still three hours from the surface and, with no main battery supply,
the sub's systems start shutting down.
First goes the heating,
and the temperature quickly drops to near freezing.
Got my warm gloves.
But things are about to get far more serious.
CO2 alarm 0.5.
Normal carbon dioxide levels in the air are 0.04%.
In the sub, they are now rising rapidly.
CO2 is 0.72, is that?
Every breath Victor takes releases more toxic carbon dioxide
into a sealed environment.
If the levels keep rising,
Victor may not have long before he loses consciousness.
The CO2 is rising rapidly.
At 1% CO2, you start to feel ill effects,
at 2% you could, I believe, pass out.
If the levels keep rising,
Victor might not reach the surface in time.
0.5 is the alarm condition.
LF, what is your O2 reading?
Confirm, both scrubbers are running.
You do have a secondary Analox unit, you can power that up.
LF, what is your reading?
Control be advised CO2 level of...
Roger. Say again. Say again your last, Victor.
Control be advised, CO2 level back down to 0.32.
Roger that. OK, man, we'll see you on the surface.
12 hours since his early morning launch,
Victor returns from the deepest place on earth.
LF, this is Xeno, welcome back, Victor.
Swimmer in the water!
LF, LF, Xeno, Victor.
Yeah, Victor, we are taking the odd wave across the top of the sub.
If you could thrust up...
Surface, be advised, using thrusters
overloaded my remaining batteries, batteries are dead.
With no power left, the sub can't fully resurface.
Swimmer Tim once more has to put his body on the line.
I got it. Back away.
OK, standby with the hand rail.
Keep an eye on that towline, boys.
Towline has come loose! Towline has come loose!
Give him slack! Give him slack! Give him slack!
You OK, Tim?
Tim? You all good?
You OK, Tim?
LF is on the hook.
That was sporty, boys.
Thank you, guys. Well done!
Thank you for coming to get me!
Despite an electrical failure and a carbon dioxide scare,
Victor has conquered the fourth of the five oceans.
Well done.
You did it, buddy. You did it!
Congratulations! Well done, sir. Thank you for showing the way.
You're my hero. Thank you. No, you're mine.
Victor Vescovo, world's deepest diver!
It was an amazing dive.
I think almost exactly 12 hours.
But I must confess there was more
life down there than I expected.
I thought it was gonna be dead,
and it is not.
I'm just glad to have you back home safe.
It's great to have him back.
It was a great dive.
It's an inspired, clever design.
And even though it's 60 years
since we did ours, this is like
stepping into the future.
Looking at a map, you take a look
at the Mariana Trench and it's
very dark and blue, even black.
It's intimidating.
I've seen the sandy bottoms.
I've seen the rocky ledges.
It's not a deep, dark, scary place.
It's tough to get to,
but there's an incredible amount of things to discover there.
We now have a tool to bring us there.
