MAN: 'The location of the search

'is approximately 900 miles east
of Cape Cod

'in a water depth of 13,000ft -

'in square miles, an area larger
than the state of Connecticut.

'Search efforts have focused
on both surface and sub-surface.

'That operation
is currently ongoing.

'This is an incredibly complex
search operation.

'Sometimes, we don't find
what we're looking for.

'We offer our most heartfelt
thoughts and prayers

'for the five crew members,
their families

'and their loved ones.'

An international
search and rescue team

is scouring the ocean for any sign
of the missing submersible

on a voyage to the Titanic.

REPORTER: 'After 48 hours lost
at the bottom of the ocean,

'will the mini sub
meet the same fate

'as the wreckage
it was looking for?'

NARRATOR: It's a story
that captivated the world,

when five men dived to the wreck
of the Titanic

and go missing somewhere
in the Atlantic Ocean.

The scale of the search to find them
is unprecedented.

Canadian Coast Guard,
French authorities.

You had American Coast Guard ships,
aeroplanes. It was frantic.

As the whole world watches,
it's a race against time.

They only have
so much life support on board,

and the oxygen is running out.

Air force sonar recordings
gave the world hope.

And I identified banging noises
that appeared to be manmade.

That's when the search
really changed direction.

The vital audio revealed here
for the first time.

RHYTHMIC TAPPING

We need to have hope, right?

We're searching
where the noises are,

and that's all we can do
at this point.

But what actually went wrong,

and how many safety warnings
were ignored...

We've taken a completely
new approach to the sub design,

and it's all run
with this game controller

and these touchscreens.

...by the self-confessed rule breaker
at the helm?

He seemed to think that he knew more
than the regulators.

So, who were they to regulate him?

We all need pioneers.
Ego is not a bad thing.

It's a great driver,
but it also can be a killer.

And what is the truth
behind this extraordinary tale?

All sorts of things
started to come out.

Fingers started to be pointed.

Everyone has a theory
on what happened.

Very few people know the answers.

April the 1 0th, 1 9 1 2,
the most famous ship ever built

set sail from Southampton
to New York - the Titanic.

Five days later,

it was two and a half miles
at the bottom of the ocean.

More than 1,500 people
lost their lives

after the 269-metre-long ship
struck an iceberg.

Now, more than a century on,

it's a story that has captured
the imagination of millions.

Since the discovery of the wreck
in 1985,

most who have dived down to it have
been salvage hunters and scientists.

But it has been an obsession
for explorers, too.

It's the Titanic.

People are fascinated
by the Titanic.

People are just transfixed
by this shipwreck and visiting it.

It's just this lure.

It's the most famous shipwreck
in the world.

The allure of Titanic
is the romance of the story,

added to the fact
that it's so remotely positioned,

two miles
at the bottom of the ocean,

so few people are able to see it.

In 2009, a company called OceanGate
was founded.

Its aim - to take paying tourists
to the Titanic

in a deep-sea submersible.

I think there was a market gap,
market need, desire, passion,

drive for opportunity
to dive the wreck,

and OceanGate saw that opportunity.

And I suspect that the lure and
the excitement of the opportunity

probably masked the risk
of what potentially lay in store.

That ship's lying
at the bottom of the ocean

not because of the nature
of its steel

or the nature of its compartments,
but just because of bad seamanship.

The captain was warned
there were icebergs ahead.

It was a moonless night,
and he ploughed ahead,

for whatever reason.

I think there was some greed,
there was some glory in it.

Ancl here we are again,
and at the same place.

Newfoundland and Labrador,
it's a small province.

It's Canada's youngest province.

There are
only about 500,000 people here.

Being close to the Titanic,

expeditions that go to the Titanic
tend to leave from St john's.

So, we had heard about OceanGate
in the years previous

and their plans to take a manned
submersible down to the Titanic.

On Friday the 16th ofjune, 2023,
a ship called The Polar Prince

sets out from St john's,
Newfoundland.

Its destination -
the site of the Titanic wreck,

400 miles southeast
in the Atlantic Ocean.

Towing behind it is Titan,

a 6.7-metre-long
deep-water submersible.

One of my colleagues
was hiking Signal Hill,

looking over the harbour,

and had taken some photos
of the Polar Prince

going out through the harbour
in St john's,

out onto the open ocean,

and you could see the submersible
being towed behind it.

By towing the Titan submersible
behind them,

it was being subjected
to far more action

in terms of vibration,
impact and exposure

than it would have been

if it was put aboard a tender
and secured deck side.

There are five people
preparing to dive 2.5 miles down.

Hamish Harding,
a British billionaire

who runs a Dubai-based
private jet dealership.

Hamish was a very amiable guy,

very nice guy,
fiercely intellectual,

thought deeply about everything,

but saw excitement
in almost everything around him.

Also on board is 48-year-old
businessman Shahzada Dawood,

from one of Pakistan's
richest families,

and his son, Suleman,
who is just 19 years old.

Their guide is 77-year-old
former French Navy commander

Paul-Henri Nargeolet.

Paul-Henri Nargeolet
was a larger-than-life character.

He was a very, very fun guy
and extremely good at what he did,

which was diving submersibles,
diving Titanic,

which he did 37 times.

Each of the deep-sea tourists

has paid nearly £200,000
to OceanGate for the trip.

The CEO of the company
will be piloting Titan for the dive.

His name is Stockton Rush.

We had spoken with Stockton Rush
on the St john's Morning Show

a few weeks prior,

and he had come on
to just kind of set up the season,

to let us know about some of the
expeditions that they had coming up.

I met Stockton Rush in 2016.
He did have a big personality.

He had a personality that you
would attribute to an explorer.

By 4am, the Polar Prince
is at the site of the Titanic,

but the conditions at sea
are too dangerous to dive.

We had a really, really, really
remarkable spring, weather-wise.

We had a lot of heavy fog,

and so I think the fog that morning
had delayed them a little bit.

You're possibly getting anxious
because of the delay, frustrated.

You just want to get into
that submersible

and get on with the dive.

I became aware of Hamish Harding's
post on Instagram.

He said, "Due to the worst winter
in Newfoundland in 40 years,

"this mission is likely to be
the first and only manned mission

"to the Titanic in 2023."

According to OceanGate's
crew waiver,

Titan has made fewer than 90 dives,

but only 13 to a depth
as far down as Titanic.

Several others encountered delays,

including one documented
by a film crew in 2022.

Candid footage captured
Stockton Rush briefing passengers.

We want everyone going into this
fully informed.

This is an experimental sub.
This is a dangerous environment.

Very few people
have been down there,

and so we want to make sure that
you're going in with an open eye

and understand what's going on.

If you don't want to do it
at any time, feel free to say,

"I want to take a pass,"
and we can work something out.

June 18th 2023, just before 8am.

The passengers
are happy to make the dive.

They've all signed a waiver
that mentions death four times

on the first page.

They board Titan.

Once locked in, they cannot get out.

One of the things
that really struck me

was that you're bolted
into the submersible.

You get in,
then they close the hatch

and bolt it shut from the outside.

Being bolted into a submarine
is a huge safety issue.

That alone, frankly,
would scare the bejesus out of me.

Once you sit in that submersible,
all the electrics have been done,

all the topside crew
have done preparation and checks

and double-checks
and gone through their check list

again and again, you're committed.

Then the hatch is shut,
and then the realisation dawns.

"This is happening, and it's
a bit late to turn back now."

NARRATOR:
In the middle of the Atlantic Ocean,

five men are about to take
the trip of a lifetime.

They are bolted inside
the unregulated,

experimental deep-sea submersible
Titan,

and they're preparing to dive
to the wreck of the Titanic.

It's just such a unique experience.

Such a once-in-a-lifetime venture.

With great adventures
come great risks,

but sometimes,
you have to take those risks.

Titanic is 2.5 miles down.

It's a dangerous environment.

At that depth,
pressure increases dramatically.

The enormous weight
of the Atlantic Ocean above

crushing down onto the submersible.

Down there, you're talking 350 or
400 atmospheres of pressure outside

versus one atmosphere pressure
inside.

If you even got a pinprick hole
in the submersible,

the pressure of the water
coming through

would be like a laser
that would cut man in half.

So why would anyone take
such extraordinary risks?

Those who've been there
say it's life-changing.

Touch down on the sea bed,
it's like a lunar landscape.

just colourless sand.

Ancl then suddenly,
within a metre of my face,

the other side of the porthole,
was the bow rail of Titanic.

just breath-taking.

Stockton Rush claims Titan
has been to the Titanic

on ten previous dives.

It captured these haunting pictures
from the deep.

Arthur Loibl is one of only
a handful of Titan passengers

to see Titanic first-hand.

And after two or three hours now,

we reached
the place where the Titanic is.

What we saw of the Titanic,
one of the first was the famous bow.

That was amazing.

Everybody was happy.

The mood was very good in the ship.
Stockton Rush was very happy.

P-H was our guide.

He was telling us
everything about the Titanic.

Every window, what happened,
who was this cabin.

Here was the captain's toilet.
Here was the captain's bathroom.

He gave us really a feeling
we are at the Titanic, 1912,

and walking around the railways
and everything.

It was amazing,
what he was telling us.

The portholes are just haunting,

when you imagine what went on
behind those portholes.

The rust that is coming
off the wreck,

running down the port,
it was like tears.

It was a once-in-a-lifetime trip.

So few people ever get the chance
to do that.

The OceanGate expedition starts
to descend to Titanic at 8am.

Titan will explore the wreck
for two hours

before resurfacing at 3pm
Eastern Time.

It will take around about two hours
to descend from the sea surface

down to around 4,000 metres.

You're so sort of excited
about the prospect,

you're not really thinking about
the claustrophobia.

You're certainly not thinking about
the likelihood

of anything going wrong
at that point.

There are various
environmental zones

that you will pass through

on your way down to a depth
of about 4,000 metres.

The first zone
is what we call the photic zone.

Everything becomes very blue.

Extraordinary,
beautiful colours you experience

as the water changes,

and you have change of different
temperatures, currents, eddies.

You then start to see
some sea life.

Then you enter into what we call
the Twilight Zone,

which is a depth of around
200 metres to 1,000 metres depth.

It gets dark, it gets pitch black

after probably about
the first hour and a bit.

The pilot turns off the lights,
and you are in pitch black.

Can't even see each other.

Maybe the odd red light
on some of the controls.

It's very still. It's very dark.

It's incredibly quiet.
It is very peaceful.

It's extremely quiet,
and it's very, very eerie.

The next stage of the journey

is the moment
the Titanic comes into view...

...but not for the Titan.

At 9:45am on the 18th ofjune,

suddenly,
communication with Titan is lost.

Those aboard the Polar Prince

would have been checking
everything that they could

to re-establish communication.

The speculation at that time was,
"Why? What happened?"

The frustration of the topside crew
would have been extraordinary.

"Something is clearly very wrong.

"How are we going to resolve this?"

I'm not sure
that they would immediately assume

something disastrous had happened.

They would want to rule out
all sorts of other causes.

There's an expectation,
as a deep-sea researcher,

that anything you put over the side
of the boat into the ocean

can fail in some way,

and often,
electrical systems will fail.

That's the most likely thing.

"They've had
some kind of power failure.

"Maybe they're taking time to get
their back-up system operational.

"Once they do, they'll be OK."

This wasn't
totally out of the ordinary.

We know that in past missions,

they had lost communications
as well.

They knew that communicating
with the submersible at that depth

was difficult.

Those in the know have speculated
about Titan's actions at this point.

Filmmaker and deep-sea explorer
James Cameron

made this shocking revelation
in an interview with ABC news.

It's our belief, we understand,
from inside the community,

that they had dropped
their ascent weights

and they were coming up,
trying to manage an emergency.

I have heard some talk

about the possibility that
they knew that something was wrong,

that perhaps their detection system
had alerted to some kind of failure

in the hull, and that they were
attempting to resurface.

If that's true, that will have been
very distressful,

particularly for the passengers.

The focus of both Stockton and P-H

would have been trying to gain
some control of the submersible,

trying to recover some height

and getting the vessel stable
and back to surface.

And that would be
their total, utter focus.

The fear that that would generate,
I can't even comprehend.

The last little while, I think,

would have been
absolutely torturous.

Meanwhile, the US Navy's
enemy submarine detection systems

pick something up deep in the ocean.

Navy had heard a noise on the clay
the Titan lost communications.

The US Navy at the time
would have said,

"Yeah, I think
we've recognised something

"that is vaguely
what we would expect

"from something like Titan
having some sort of incident.

"We've got to analyse it.
We've got to make sure."

Back on the surface,

there is an anxious wait
for those aboard the Polar Prince,

which includes some family members
of the Titan's crew.

You can imagine, you're 685km out
on the Atlantic Ocean,

lose communications
with the submersible,

the panic that would have set in

on board the Polar Prince
at the time.

The person that
I identified most strongly with

through all of this
was Christine Dawood,

who's the mother of Suleman Dawood,
who was on the support vessel,

the Polar Prince, when she heard

that all communication
had broken down.

She had given up her place
in the submersible

so that her son
could have the experience

of going down
and seeing the Titanic,

and suddenly this, and you imagine
this hellish, nightmare scenario.

Time ticks by.

Five hours later, 3pm,

the Titan
failed to come back to the surface

as it was scheduled to.

Bearing in mind
that they'd lost contact,

you would think
alarm bells were ringing

when there was still no sign
of Titan at the surface,

when it was meant to be there.

Worse still, the submersible
only contains limited life support,

and it's been slowly running out
since the hatch was bolted shut.

They were equipped
with about 96 hours of oxygen

on board the Titan,

and at that point, the clock
had been ticking for some time.

It would have been
absolutely freezing.

It would have been dark, they would
have been running out of oxygen.

So we knew the situation
that these people were in

wasn't gonna be good.

At 5:25pm Eastern Time,

the crew of the Polar Prince
alerts authorities,

nearly eight hours after losing
communication with the Titan.

There was a gap of eight hours

before the mothers hip
contacted shore authorities

to let them know
there was an issue and a problem.

Emergency services
like the coast guard,

they would want every hour,
every minute,

to be able to come up with a plan
in order to effect a rescue.

But finally,
a rescue mission is about to begin.

It was a rescue operation.
As far as we knew, it was missing.

Ancl could it be found in time
before the oxygen ran out?

We knew then
that this was going to be a massive,

massive, massive search effort.

It was going to be
a monumental effort,

and the people
down in that submersible

would fully be aware of that
and fear the worst.

You don't give in
until the very last moment.

Never, ever give in.
It's a sports thing.

It's an expedition thing.
You just never give in.

If there's 1 % chance that people
can be rescued, you go for it.

You've got to put your resources
into doing that

and try and rescue them.

NARRATOR:
400 miles off the coast of Canada,

five men were on what should have
been the trip of a lifetime,

diving to the wreck of the Titanic.

But communication has now been lost
for eight hours,

and their oxygen
is thought to be running out.

Knowing the dangers, I was fearful
it was not going to end well

because I can't imagine the terror
that they would be going through

at the bottom of the ocean.

At 5:25pm,
the first distress call goes out.

The Canadian Air Force answers.

I'm Major Dawn McCauley,

and I'm a search and rescue
helicopter pilot.

I can proudly say I've been part
of the Royal Canadian Air Force

for 18 years.

We were the first point of contact
from the Polar Prince.

I was listening in to the call,

and I feel like my face probably
was a little bit in shock.

You know, kind of in like a,
"Whoa, this is intense, right?"

The Canadian Air Force
is being called in

to carry out surface searches,

flying over the ocean
to spot any sign of Titan.

They will deploy
a specialist aircraft,

the CP-14O Aurora.

The CP-140 Aurora
is the long-range patroller.

They are the main asset
for Canada's air force

when it comes to intelligence,
surveillance and reconnaissance.

Ancl they have a sensor suite that's
conducive to anti-submarine warfare.

So essentially,
use those capabilities

to find a commercial sub,
in this case. They're a sub hunter.

It's a huge task,
and time is slipping away.

It's a scary, scary situation
to put yourself into and to imagine.

You know, some people
would prefer not to imagine it,

but I think from a compassionate
search and rescue perspective,

it's important for us
to put ourselves in that situation.

And you're hopeful.

You want to bring those people
back to their families.

That's what's driving you.
That's what's motivating you.

But searching from the air
has its limitations.

Our search and rescue expertise
kind of stops at the surface.

It's not part of our mandate.

We have nothing written in manuals
to search underwater.

If Titan is at the bottom
of the ocean,

the only way to reach it is with
another deep-sea submersible.

But there are only ten in the world
capable of diving to those depths,

and the closest one
is nearly 2,000 miles away.

My name is Jesse Doren.

I'm the ROV manager here
at Pelagic Research Services.

I manage the subsea equipment
that we have.

On Sunday, June 18th,

I got a call
from one of my colleagues

that started the whole thing
rolling here.

He told me he was working
with OceanGate,

and they had a manned submersible
in the water

that they lost contact with,

and they were approaching the time
when the submersible

should have returned to the surface
automatically

in an aborted-mission type scenario.

Our capabilities
go down to 6,000 metres,

so we were well suited to get down
to the depths where Titanic lies

and effect a search and rescue
if needed.

This is the Odysseus
6,000 metre vehicle.

This is a remotely operated vehicle.

The vehicle itself,
the Odysseus 6K,

is equipped
with a variety of cameras

looking in a variety of directions

to give the pilot
a sense of place and space.

But before you can see something
visually,

we can also see something
through acoustics,

and we bring a sonar down.

This vehicle is rated
to go to 6,000 metres,

and that means
everything on the vehicle

can withstand that kind of pressure.

We were called immediately after
the Coast Guard was contacted.

It was the opportunity
to rescue the crew of Titan.

Ancl now our plan was go to seafloor,

locate Titan,
start bringing Titan to the surface.

But the planning process typically
to go on an operation like this

takes weeks or months.

We had clays.

We were hyper focused on rescue

from the moment we got the call,
and that's when our clock started.

But really,
the clock that we were under

was, of course,
when the hatch was closed on Titan.

If they are
at the bottom of the ocean,

the Titan crew
face an agonising wait

while rescue teams mobilise.

And the next morning,

the news reaches the mainland
for the first time.

People were starting to come in
at around 9am,

when we got a phone call
to the newsroom.

A reporter had asked us

if we knew anything about
a submersible that had gone missing

off the coast of St John's,

and immediately,
we knew that this had to be Titan.

The story is about to explode
internationally.

It was absolutely wild

to see the world's media descend
on St john's.

A deep-sea submersible

used to take people
to view the wreck of the Titanic

has gone missing
in the Atlantic Ocean.

Trapped in a tiny submarine
far beneath the ocean surface

with time and oxygen running out.

There was a global media
feeding frenzy.

There was something in this story
to appeal to everybody.

Didn't matter where you lived
in the world.

The tourist sub that's vanished

thousands of metres below
the surface of the Atlantic Ocean.

SPEAKS OWN LANGUAGE

SPEAKS GERMAN

It was one of those things

that just
grabbed everybody's attention,

and we all became obsessed with,

"ls there a chance
they're gonna get out alive?"

For the Coast Guard and the Navy,
it is a race against the clock.

Oxygen levels inside it
are dropping.

It was an international story that
was breaking and developing quickly,

right in our backyard.

The Coast Guard headquarters
is right down the street

from the Globe offices.

This particular story stood out

from, really, all the other stories
I've covered.

Such a compelling story
on so many different levels.

You have an experimental submersible

with tourists going down
to visit the wreck.

You had the time component,

you know, that 96-hour window,
and everybody was counting down.

The world was watching.

Everywhere was reporting on it.

There was a massive interest
in the whole rescue operation.

That something's missing
whilst diving down there

immediately makes it of interest
to the public.

You throw in, "Oh, it's tourists
going down there,"

and then it's, "Oh, it's billionaire
tourists going down there."

It was absolutely guaranteed,
really,

to be at the forefront
of all of the news.

Now the price for this trip
is extremely high-end -

£195,000 per person.

That was one of the things

that really caught a lot
of people's interest early on,

was when they saw the price tag.
$250,000 per person is enormous.

And it's something that's
out of reach for 99.9% of people.

That turned heads.

As the story began to unfold,
more and more information came in

about the resources available
to try and find the submersible

and then to recover the submersible
if it was still down there.

The search might have been
the only thing more frantic

than the news coverage.

On Monday morning,

the Canadian Air Force launches
the CP-14O Aurora.

We were actually the first crew
to go out on that Monday morning.

The crew was 13 people,
for that particular mission.

My role in that
was the communicator,

to speak from the aircraft
to our tasking authority,

to let them know
how the mission was progressing.

I'm at the ops desk
in a room just like this one.

A lot of what we do

is making phone calls
to task the aircraft,

to coordinate what the tasking is,
where they want to be,

making sure that everybody's
kind of on the same page.

We actually flew for about 11 hours
on our sortie.

That is time to get
to the scene of action,

and then six, six-and-a-half hours
actually conducting our search.

Ancl then obviously,
we have to come home.

When we were coming home,

there is another aeroplane that
had been made ready, had a crew.

They were briefed,
and they came out to replace us.

We're given a search area
to start with,

saying this is where we believe
the object to be.

Over time, because of ocean currents
and the wind,

that area will get bigger
and bigger and bigger.

As well as searching
the expanding surface area,

Captain Thomas and his crew
are also listening under the water

by using state-of-the-art equipment.

Sonobuoys that we dropped
from the aircraft

basically listen
to noise in the water.

Sound in the water
travels further and faster

than it does in the air,

so using those facilities
from the sonobuoys,

we will put them into the water
to see what is unusual.

If there's things that perhaps
shouldn't normally be there

in the water,
then we will try and figure out

where the source of that noise is.

We would then report that
to the Boston Coast Guard

because they were the main people

who were driving and coordinating
the search activities.

We just wanted to give them
everything we had to help out

because I think we recognised
the scale of the situation.

By late afternoon,

the world heard from the man
in charge of the search effort.

The location of the search

is approximately 900 miles east
of Cape Cod,

in a water depth
of roughly 13,000ft.

We are deploying
all available assets

to make sure
that we can locate the craft

and rescue the people on board.

We've coordinated
with the Canadian Coast Guard

and Canadian Armed Forces to deploy
additional assets to the scene.

It seemed like
there was this collective hope.

For as long as the Coast Guard said
it was a search and rescue mission,

there was that hope.

You had Canadian Coast Guard
and American Coast Guard.

You had any equipment
that might have been helpful

anywhere on the eastern seaboard
of the United States.

Were we focused on rescue?
The answer is absolutely.

Ancl not only were WE focused
on rescue,

the entire international response
was focused on rescue.

With the world now watching

and an international search effort
getting underway

both above and below the sea,

there is a belief
Titan will be found in time.

We had the time
in which the oxygen ran out

on the board in our ops room,

so we were very, very aware of when
this search was going to end.

Titan has been missing
for more than 24 hours.

At least five planes

and a Canadian Coast Guard
icebreaker are searching for it,

with more ships on the way.

What we're really focused on
is locating the vessel,

which could either be on the surface
or sub-surface.

Ancl so we're bringing in
technical expertise

to understand the dynamics

of underwater search
and underwater rescue operations.

One of the first phone calls
that I had made

was to a man named Miseljoe,

who owns the Polar Prince,

so I knew
that he would be in the know.

And so I spoke with him,
and he said,

"The fog is really thick out there.

"They're hoping that they surfaced
and we just can't find them."

There's some hope that
they did make it to the surface,

but they're just out of sight,
they're lost somewhere in the fog.

If Titan did resurface, a rescue
is still not straightforward.

The surface search
is more than 7,500 square miles,

an area roughly the size of Wales.

And with comms lost,

the crew would have no way of
letting anyone know where they are.

One of the most worrying things
about Titan

was it was secured
by these 15 very heavy bolts,

so even if you got to the surface,
you couldn't actually get out of it.

So there was a chance
that you could run out of air

even though you're on the surface.

My concern was that you'd have
people freezing to death

because of the conditions.

You're not insulated, and you're
suffocating at the surface.

They would have no way to get out.
They would be trapped in there.

Immediately, your brain goes to a
very claustrophobic place, I think.

I thought this was a situation
where you had people

that could look out that window,

see the air, see the surf,

and still be suffocating,
waiting for rescue.

For the search for Titan,
because it's in the water,

you don't know whether it could
be floating on the surface,

or it could well
still be under the water.

Making many people question
which would be worse -

lost on the surface
or lost on the seafloor.

The sea is unforgiving.
It is cold underwater, it is dark.

There are so many challenges.

My heart really went out
to these people -

not just the families,
the people in that situation.

It's incredibly cramped.

If you picture yourself
in a tube-shaped vessel

the size of a minivan,

cramped together with four
other people in the dark water,

the situation is like
the stuff of nightmares.

It's not just confinement
to contend with.

Temperatures that deep down
can dip to 2.5 degrees.

It would likely have started
to get very, very cold.

I'm told they had some kind
of heating system,

but they probably would have had
to shut that down

if they needed to conserve energy.

There would have been condensation.
It would have been very dark.

It's an awful situation to be in,

ancl as soon as panic sets in,
you're in an enclosed space,

I'm sure it would have been
particularly horrific.

There is hope, you know,
that the lives can be rescued,

but if they were underwater,

that would be extremely difficult
to pull off a rescue.

That's all part of what made
this story so interesting

and so captivating for people.

It's one part adventure

and one part horror.

If Titan is on the seafloor,

their hopes may rest
with one specialist team,

and they are racing against time
to reach Titan

before the oxygen runs out.

But they are 2,000 miles away
and need help getting there.

We were at the airport 0400,
and the loading began.

The Air Force
was sending heavy-lift aircraft

to the Buffalo
International Airport,

and that was the result of actually
OceanGate contacting the air force.

The kit is about 30 tonnes
of equipment.

Three Air Force C-17s
gave us a ride.

We would not have been there in time
if it wasn't for them.

We had to get there
as fast as possible

because there were people in trouble

and their oxygen resources
are limited, and we knew that.

That was definitely in the back
of our mind all the time.

The minutes ticking by
and, you know,

we were doing everything we could

to make the next step
go as smoothly as possible.

The first aircraft departed
early to mid-morning on the 20th.

I got on the first plane
with a couple of my colleagues,

and the rest of the stuff and the
rest of the folks were gonna follow.

With the assistance
of the US Air Force,

the Odysseus crew
are now on the way,

but it will still take them
a day and a half

to reach the Titan dive site.

As time wears on,
hope is beginning to fade.

Titan has now been missing
for more than 60 hours.

In Newfoundland and Labrador,

we cover a fair amount
of nautical disasters,

and we know that when contact
is lost that far out,

it usually doesn't end well.

On top of the sea,
people don't survive,

but down below,
in frigid, deep, dark water,

your odds of survival
are even slimmer.

But then
an extraordinary development.

Late in day two,

CNN reports that the Canadians
have heard banging noises

at 50-minute intervals
from under the ocean,

and that changed everything.

This is the sound that was heard.

RHYTHMIC TAPPING

Sounds like
it could be somebody knocking.

The symmetry between those knockings
is very unusual.

RHYTHMIC TAPPING

It's rhythmic, it's like
somebody is making that sound,

and the fact that it's repeated
is really unusual.

The reports of banging
quickly spread.

Could the sounds mean
a rescue is possible?

Maybe the banging sounds
were coming from the Titan.

So people were like,
"Oh, my God, they're still alive."

Next time, the sonar audio
intensifies the hunt for Titan.

That's when the search
really changed direction,

bringing industry
and bringing militaries

and bringing countries together
to try and save these people.

And experts reveal
the shocking truth

behind Titan's design flaws
that Stockton Rush was warned about.

You put people at risk who had
no idea what risks they were taking.

You just don't get chances
when you go that deep.
