NARRATOR:
March 23, 2021.

The Ever Given,

one of the largest container ships

ever built...

[loud thudding]

...plows into the bank
of the Suez Canal.

The only thing that ran through
my mind was, "Oh, my God."

JULIANNE CONA:
I posted the picture,

and my sister's like,
"It's all over the news."

NARRATOR:
It completely blocks

one of the most important shipping lanes

in the world for nearly a week,

triggering a global emergency.

No one had had a vessel
the size of Ever Given

run aground in the way Ever Given did.

NARRATOR: Now, eye witnesses
speak out for the first time.

CONA: It was life-changing,
I think it changed

the perspective of a lot
of people on board.

NARRATOR: And using clues
from former maritime disasters...

ROD SULLIVAN:
He stayed there

to the very last minute

to try to save the
life of this one seaman.

NARRATOR:
New documents,

expert analysis,

and never-before-seen footage...

ERNEST CAPONEGRO: We thought
the ship was going to collide with us.

I ordered everybody off the stern.

NARRATOR: We investigate
what really happened.

You're dealing with a
machine, really, that is

one of the largest machines
ever created by man.

NARRATOR:
Was this a freak accident?

And how can we stop a disaster like this

from ever happening again?

SULLIVAN: The Ever Given
was a wakeup call to everybody.

And if those ships don't arrive,

you can shut down an economy.

If you didn't get the message
from the Ever Given,

you weren't paying attention.

NARRATOR:
The Suez Canal...

a 120-mile artery that runs
through the heart of Egypt,

linking the Red Sea to the Mediterranean.

A shortcut that saves
ships thousands of miles,

and several weeks of sea time.

[translated]:
We have 18,000 ships

pass through each year.

We are the most important
maritime route in the world.

NARRATOR: Hundreds
of thousands of containers

loaded with critical supplies:

fuel, food, and medical equipment

depend on this man-made waterway,

a narrow strip of water
stretching improbably

through Egypt's Eastern Desert.

♪

[water crashing]

10:15 a.m. local time,

March 9, 2021.

The container ship
Ever Given sets sail from

the south coast of China,
loaded with more than

700 million dollars' worth
of cargo and consumer goods.

Operated by the Evergreen
Marine shipping company,

it's nearly as long as the
Empire State Building is tall,

and capable of carrying 20,000 containers,

one of the biggest container
ships in the world.

It's scheduled to spend the next 23 days

sailing halfway around the world

to deliver its cargo to ports in Europe.

To get there,

it must pass through the series of lakes

and narrow channels that
make up the Suez Canal.

♪

♪

The Ever Given arrives
at the Southern mouth

of the Suez at 6:00 p.m.
on the 22nd of March.

[indistinct chatter]

Captain Reda Ahmed oversees
this section of the Canal.

[translated]:
I was working as the head

of sea traffic in Port Tawfik.

NARRATOR:
Reda is a veteran mariner

who has worked with the Suez
Canal Authority for 26 years.

♪

He manages a team of
local maritime pilots,

expert sailors who board

every vessel to help guide
it through the canal.

In the south, the waterway is too narrow

for big ships to pass each other,

so Reda organizes the
vessels heading north

into one-way convoys sailing single file.

[translated]: The speed of the
ships at the front of the convoy

is different to the speed of the ships

at the back of the convoy.

CONA: It's slow moving,
it's a very long day.

It's the last major obstacle

before you're going back across
the Atlantic, headed...

headed home.

NARRATOR: Julianne
Cona is on the ship directly

behind the Ever Given, the Maersk Denver.

With eight years' experience,

Julianne has sailed the
Suez a dozen times before,

working as an engineer
in the ship's engine room.

Being aboard these vessels,

it can be challenging at times.

Things constantly are changing,

but you kind of learn to roll with it.

NARRATOR: For the biggest
ships, navigating the Suez

is a serious challenge.

CONA: You've got land
on both sides of you,

you've got a ship in front
of you and a ship behind you,

and the slightest misstep
on anybody's part

could end in a maritime accident.

NARRATOR: At 7:00 a.m.,
the Ever Given sets course

from the Gulf of Suez
to the canal entrance,

as part of a convoy of 20 ships.

The Maersk Denver
is just ten minutes behind.

CAPONEGRO: I got on watch
at midnight and from then on,

it was calm, calm, and then
the wind started coming.

NARRATOR: Ernie Caponegro has
been a licensed officer for six years,

sailing cargo ships all over the world.

CAPONEGRO:
Wind picked up suddenly from

a light breeze to around 20 knots,

and it just continued on up from there.

NARRATOR: By the time the
Ever Given enters the canal,

the wind is gusting at gale force.

That's when it started to
become a little more concerning.

NARRATOR: It may seem like a
ship as massive as the Ever Given

would be unaffected by wind,

but its tall sides can act like a sail,

pushing it sideways
and making it difficult

to maintain its position.

♪

When you have a vessel that's
equal to a 15-story building

above the waterline,

and as long as nearly
four football pitches,

this is a vessel that, if it is
blowing and gusting wind,

she is going to move around.

That vessel needed to be
dead center in the canal.

There's very little room
for margin of error.

♪

NARRATOR:
Satellite tracking data shows

that the northbound convoy
makes steady progress.

But the data also reveals something

is wrong with the Ever Given.

♪

At 7:18 a.m., the ship is off
the center line,

too close to the west bank.

Then, 16 minutes later,

it runs dangerously
close to the east bank.

At 7:38, it finally
loses control.

On the bridge, the crew shout,

"We might be grounding...
stand by."

♪

The bow of the 219,000-ton ship...

[loud thudding]

...crashes into the east
bank of the Suez Canal.

With the bow of the Ever Given aground,

and all steering control lost,

the wind and current now pushes the stern

right across the canal, until it wedges

into the other bank.

The Ever Given is firmly lodged,

blocking the entire Suez Canal.

♪

What caused the accident is a mystery.

♪

On the Maersk Denver,

Ernie and the rest of the crew
can't believe their eyes.

♪

The only thing that ran through
my mind was, "Oh, my God."

CONA:
Oh crap, I guess

I'm not going home.
[laughs]

NARRATOR:
Ernie and Julianne are now

steaming directly towards the Ever Given.

CAPONEGRO: My vessel was
weighing 110,000 gross tons.

Stopping that with 35 to 40 knots of wind,

plus a two knot following current,

not exactly an easy feat.

NARRATOR:
The captain of the Maersk Denver

reacts fast and throws
the engines in reverse.

CONA: It was the first time
in my career I'd ever seen

a complete full astern bell.
[bell chiming]

It's not very often that you're going

as fast as you can backwards.

♪

The ship stops just
a few hundred feet before

it plows into the Ever Given.

♪

But the ship directly behind them,

the Asia Ruby III, is in serious trouble.

♪

Something in the back of my head
said, "Turn around and look."

And when I turned around,
the Asia Ruby III was maybe

a football field away.

NARRATOR:
This phone footage shows

the nearly 70,000-ton ship

heading right towards the Maersk Denver.

CAPONEGRO: We thought the
ship was going to collide with us.

I ordered everybody off the stern.

NARRATOR: The Denver's
captain quickly guns the throttle.

♪

Their ship slowly moves forwards,

away from the Ruby.

They narrowly avoid
a catastrophic pile up.

CAPONEGRO: If the
ship behind us had hit us,

they could have very
easily just disabled us,

sending the ship barreling
towards the Ever Given.

♪

NARRATOR: Once safely
anchored, the crew can fully grasp

the scale of the accident.

CONA:
I called my family

and my sister's, like,
"It's all over the news."

GERMAN NEWS ANCHOR [translated]:
More and more ships are waiting.

Some captains are even

considering taking the 6,000
kilometer detour around Africa.

♪

NARRATOR: The shockwaves
from this accident

are felt across the globe.

About 12% of world trade

passes through the Suez Canal.

Even a short blockage
results in delivery delays

of crucial food, fuel,
and medical supplies.

♪

The 58 ships queuing up unable
to pass through the canal

all feel the consequences

of this ballooning maritime disaster.

♪

The Ever Given accident made
headlines around the world.

But there are many more that don't.

Each year, there are over 2,500 crashes

and shipping incidents.

They damage infrastructure,

and cause delays,

destroying ships,

and putting lives at risk.

MERCOGLIANO: The way
world shipping works today is

through a system known
as just-in-time logistics.

What happens is most factories,
most warehouses,

don't have enough supplies
to last more than a few days.

It requires the daily infusion

of new cargo and new supplies coming in.

Most of the time, the public
are blissfully unaware

of how their goods get to their shops,

or how components get to factories.

NARRATOR: Today, the transportation
of almost all physical goods,

from durable items
like furniture, clothes,

and computer chips, to perishable goods

like vegetables, meat, and medicines,

revolves entirely around
a single, extraordinary

piece of technology...

The shipping container.

♪

MERCOGLIANO: Prior to the
introduction of containerization,

cargo was moved in what's
referred to as "break bulk."

Basically, you moved individual pieces

of cargo... boxes, cartons,

pallets, bales, one at a time.

NARRATOR: This process of
moving cargo was labor intensive,

and time consuming.

Teams of dock workers would
take several days to load

and unload even a medium-sized ship.

♪

In 1956, American truck
hauler Malcolm McLean

unveiled a time-saving solution.

♪

What is now called the
intermodal shipping container,

a strong lockable steel box,

specially toughened to withstand
the rigors of life at sea.

♪

It evolved through the '60s,

and now containers all across the world

come in standard sizes,

with standardized attachment points.

♪

This makes it much faster and cheaper

to shuttle goods from truck and train

to ship, and back again.

♪

Today, container ships transport

around two billion tons of goods a year.

Their success changed the
way we ship goods forever.

The larger a ship,

the more efficiently
it carries containers.

So container ships grew bigger...

and bigger.

Since the 1950s,

they've tripled in length.

The latest ships,

known as Ultra-Large,

are as long as four football fields.

They're pushing at the boundaries

of what's possible in terms
of where the ships can go

and how safe is it to transport

things around the world
on these megaships.

As ships get bigger,

the margin for error gets smaller.

NARRATOR:
The Ever Given is one of

the biggest container ships in the world.

Its fate now hangs in the balance.

♪

At the canal control center,

Captain Reda makes sure
the other ships stuck

in the convoy are safely anchored,

and then heads straight to the crash site.

[translated]: This was the first
time in my life that I saw a ship

of this size stranded.

NARRATOR: He and his
colleagues at the Canal Authority

will work to devise a salvage operation

to unblock the waterway fast.

There are dozens of ships
stacking up behind,

with vital supplies on board.

The pressures to free the Ever Given

and unblock the canal are immense.

♪

But the front of the ship is buried nearly

40 feet in the eastern bank,

and the stern is stuck fast, too.

♪

The team dispatch as many
tug boats, dredgers,

and excavators as they can
lay their hands on.

Several tugs, some pushing,

others pulling, try to free the ship.

But it simply won't budge.

♪

No one had had a vessel
the size of Ever Given

run aground in the way Ever Given did.

NARRATOR: The ship's
bow has plowed into the bank

of the canal with such force,

that it is completely embedded.

The excavators look like toys
alongside the vast hull.

36 hours after the crash,
excavators and dredging ships

are still racing to scoop and
suck sand away from the bow.

The operation is extremely risky.

If the Ever Given moves
suddenly, its vast bulk

could crush anyone working nearby.

After three days of non-stop
digging and dredging,

the Ever Given remains stuck.

World shipping faces an escalating crisis.

[birds squawking]

CONA: Now you have this backup of 20, 40,

60, 80, and before you knew it,

hundreds of ships sitting there waiting.

NARRATOR:
Every day the canal is blocked,

nearly $10 billion worth

of vital medical supplies, food,
and other goods are on hold.

♪

Even a short delay creates
a huge global problem.

When you create a disruption
such as the shutdown

of the Suez Canal, that creates a backlog.

All of a sudden that smooth supply

has a big kink right in the middle of it.

The problem is, the kink resonates

down the entire supply chain.

♪

Today, the container
revolution means that ships

carry up to 90% of all global trade goods.

Every day, nearly a thousand
vessels must pass through

a handful of crucial shipping arteries,

including the Panama Canal
in Central America,

the Strait of Malacca in Asia,

the Straits of Gibraltar,

the English Channel,

and the Suez Canal.

♪

Here, closure can mean delay,
or a major diversion,

adding at least ten days

and thousands of miles to a ship's route.

CONA: A lot of ships had
decided to go down around

the Horn of Africa, just because

they'd be so far back in the line.

NARRATOR: This blockage will
affect many thousands of small and large

businesses waiting for goods
on the backed-up ships.

♪

The Ever Given was meant
to unload its cargo

in Rotterdam in the Netherlands,

and Felixstowe in the United Kingdom.

From there, the cargo
would be transported to

dozens of discharge ports,
and on to destinations

across mainland Europe and Scandinavia.

♪

But the ripple effects
of the backlog of hundreds

of ships have a truly global impact.

♪

The consequences of
the blockage are felt from

ports in the U.S.
to the docks of Africa.

Four days after the Ever Given crashes,

satellite data shows
hundreds of ships backed up,

some in the Gulf of Suez...

and others in the Mediterranean
at the north end of the canal.

♪

CONA: The cluster of ships sitting there

was crazy to watch.

Hundreds of ships just
anchored up around you.

You couldn't look in front
of you and not see a ship.

NARRATOR: With the
world watching every move,

the Canal Authority is under huge pressure

to free the Ever Given, fast.

They bring in an international team of

salvage experts with more equipment.

Together, they devise a new strategy.

Small tugs will line up

to push near the stern of the Ever Given.

Two larger tugs will use tow lines

to pull the stern away from the west bank.

Other large tugs

will try to pull the bow
away from the east bank.

But if they're not careful,
there's a real risk

that the ship could jerk free too quickly

and smash into the other
side of the canal.

[ship rumbling]

[loud thud]

This operation takes advantage
of an unusually high tide

produced when the moon is full,

and at its closest to the earth.

They begin just after midnight
on the 29th of March.

This is when the spring tide flows south.

It should help push the Ever
Given's stern off the bank.

At first, it doesn't seem
like their plan is working.

Everything hinges on them
freeing the ship tonight.

After six days of digging,
pushing, and pulling,

[Reda speaking]

[translated]:
The crew and I were so

full of joy when the ship was floated

that we didn't notice all the tugs

surrounding us in celebration.

Everybody just...
huge sigh of relief.

CONA: It almost felt like
you could breathe again.

Like, okay, we're going home.

RABIE [translated]: In the
world of salvage operations,

it is a miracle for it to have succeeded

in such a short time,
and for such a big ship.

♪

NARRATOR: The salvage
operation is a triumph of cooperation

and ingenious engineering.

But the crash has disrupted
billions of dollars

of world trade in the
midst of a global pandemic,

when supply lines are already stretched.

[ship horn blares]

Investigators urgently need
to find out what went wrong.

♪

But uncovering why the Ever Given crashed

won't be straightforward.

MERCOGLIANO:
Ever Given herself was operated

for Evergreen Marine,
a company out of Taiwan.

The owner of the vessel was in Japan.

The insurer for the cargo
was in the United Kingdom.

The crew was Indian,
the registry was Panamanian,

and investigating an accident like this,

you would see nearly all
those elements involved

conducting simultaneous,
in some cases, investigations,

along with the Egyptian
Suez Canal Authority.

NARRATOR: The key question
investigators have to answer

is why the ship lost control,

veering so wildly from
one bank to the other.

Early reports mention one thing...

the weather.

CONA:
It was exceptionally windy,

and usually in windy situations,

they evaluate the bigger ships
going in and not going in.

NARRATOR:
Most ultra-large cargo ships

have powerful engines and
are surprisingly maneuverable,

but strong winds can still pose problems.

To understand the danger wind presents,

it's helpful to look at other incidents

where ships ran into
unexpected difficulties at sea.

♪

On January 26, 2016,

the Modern Express cargo ship,

carrying a 3,600-ton load
of heavy machinery and logs,

was approaching the Bay of Biscay,

on route to Le Havre, France.

In Finisterre,
on the north coast of Spain,

coast guard Manuel Capeáns AÁlvarez

was due to start his shift.

[translated]: The wind and
rain were battering heavily.

On the days of adverse weather conditions,

you always fear that something
serious could happen.

NARRATOR: As the Modern
Express crossed the Bay of Biscay,

strong winds forced the ship off course.

The gale caught the high
side of the ship like a sail.

The vessel developed
a dangerous 40-degree list.

At 1:16 p.m.,

the captain sent a distress call.

[AÁlvarez speaking Spanish]

[translated]: The crew
requested to abandon the ship.

Two rescue helicopters and
a rescue plane were deployed.

NARRATOR:
The 22 crew members were

clinging to the steeply sloping deck,

battered by more than 16-foot-high waves.

They feared the ship could
capsize at any moment.

[waves roaring]

The wildly pitching deck

made the helicopter rescue
incredibly dangerous.

RESCUER [speaking Spanish]:

RESCUERS [speaking Spanish]:

NARRATOR:
It took around four hours

to haul all crew members
to safety one by one.

♪

No one knows exactly
what caused the accident.

But the high sides of
the ship and strong winds

were almost certainly key factors.

CAPONEGRO: Weather
plays with ships all the time.

Doesn't matter whether you're
going through the Suez Canal,

or you're crossing the Atlantic,
it's going to play with it.

NARRATOR: So how did the
strong winds affect the Ever Given?

Francesco Morelli is a marine surveyor

who has conducted dozens of investigations

into major shipping accidents,
including in the Suez Canal.

He's analyzed the data
from the Ever Given crash.

[Morelli speaking Italian]

MORELLI [translated]: The first
time I heard about the Ever Given,

what I read wasn't convincing.

So I decided to use
the same technology that

we usually use to understand
what happened exactly.

NARRATOR: All big ships like
the Ever Given are equipped with

an Automatic Identification
System, or A.I.S.

This uses satellite data
and the ship's radio

to broadcast the vessel's
precise location,

heading, and speed every few seconds.

MORELLI [translated]: The availability
of this data has made it possible

to reconstruct this scenario
in great detail.

♪

NARRATOR: Weather models
of the day of the Suez incident

show that a 30 to 40 knot wind

blasted the Ever Given
as it entered the canal.

[speaking Italian]

[translated]:
The ship was hit by the wind

on its right side.

This caused the ship to be
pushed towards the left bank

and away from the
center line of the channel.

NARRATOR: For Francesco,
even though the ship

didn't hit the bank this time,

it never really recovered the center line.

♪

But he's convinced that wind

isn't the only factor
that caused the crash.

He discovers that the ship
ahead of the Ever Given,

the Cosco Galaxy, which was
almost exactly the same size,

forged a smooth passage
through the waterway,

despite having to battle
the same windy conditions.

♪

Why did one ship sail
through the canal safely,

and the other crash?

♪

Francesco overlays the tracking data

of the Ever Given and the Cosco Galaxy.

The resulting image

lays bare the different paths
of the two ships.

As they entered the canal,

the wind pushed both ships
towards the left bank.

The Ever Given veered particularly close.

Both ships then slightly
increased their speed

as they approached a bend.

This would have made
them more maneuverable...

the more water that rushes
past a ship's rudder,

the faster it turns.

But halfway through the bend,
the Galaxy slowed back down,

while the Ever Given sped up.

[Morelli speaking Italian]

MORELLI [translated]:
The difference between the two

is that they went through
the curve of the canal

at different speeds.

The Cosco Galaxy kept a
moderate and constant speed.

The Ever Given increased its
speed up to nearly 14 knots.

NARRATOR:
In strong winds,

big ships are often easier to control

the faster they go.

But within the confines of the canal,

high speeds can cause problems.

[Morelli speaking Italian]

MORELLI [translated]: When a ship like the
Ever Given nears the side of the canal,

hydrodynamic effects suck the
ship towards the nearest bank.

This is called "bank effect,"

and the bigger the speed,
the bigger the bank effect.

[water rushing]

NARRATOR: As the Ever
Given moved through the canal,

its vast bulk displaced

hundreds of thousands of tons of water.

This rushed past the hull,

and formed a bow wave at the front.

Francesco believes that as the ship

got close to the bank,

the bow wave formed a cushion

that pushed the bow away.

But further back, as the gap between

ship and bank narrowed,
the water flowed faster.

When a fluid speeds up,
pressure in the fluid drops,

which in this case created suction

that pulled the stern towards the bank.

Just a small increase in speed leads to

a big increase in this
so-called bank effect.

Francesco's analysis suggests
that the Ever Given's high speed

caused it to lurch from experiencing

bank effect on one side of the canal,

to bank effect on the other,
and eventually to crash.

[loud thudding]

[Morelli speaking Italian]

[translated]: The behavior
of the ship is similar to

a ball bouncing back and forth
from one bank to the other.

The speed of the ship increases,
and the bank effect

becomes stronger.

This is what causes the ship to crash.

NARRATOR: So why did
the Ever Given speed up?

Faced with high winds, could the captain

have simply made the wrong call,

gone too fast and
lost control of his vessel?

How do crucial decisions like this

get made on the bridge of a ship?

Clues lie in another
tragic maritime disaster.

♪

On September 30, 2015,

the cargo ship El Faro,

carrying 391 containers,

over 100 cars, and 33 crew members

was sailing 80 miles from Florida

en route to Puerto Rico.

The ship was on a regular route between

Jacksonville, Florida,
and San Juan, Puerto Rico,

and it made that trip back and forth

week after week after week.

NARRATOR: Rod
Sullivan is a maritime expert

and was the lawyer who represented one

of the families of the crew on board.

In Jacksonville when they left,

and as they went down the
east coast of the United States,

the weather was beautiful.

There was a light hurricane,

Joaquin, force one or force two,

out somewhere in the Caribbean.

But at the very time
they left, they had no idea

that they were going to be
sailing directly into it.

NARRATOR:
Hurricane Joaquin strengthened,

turning into a category four storm

with 135 mile-per-hour winds

and mountainous seas.

The winds are getting stronger,
the waves are getting stronger,

and the ship is becoming
less and less controllable.

NARRATOR: The captain of
the El Faro, Michael Davidson,

could have changed course,
and taken a longer route

that avoided the worst of the weather.

But in the face of the gathering storm,

the El Faro did the unthinkable.

It sailed straight into
the heart of the hurricane.

SULLIVAN:
You're looking at

120 mile per hour winds,

which are, are extreme winds.

And you're also looking at high seas,

which are going to batter the
ship on one side or the other.

It's going to make it very
difficult to control the ship.

[waves crashing]

NARRATOR:
At 7:12 a.m., the captain sent

an emergency message.

Then, silence.

SULLIVAN: They sent out
fixed wing aircraft looking for

the location of the sinking.

They sent out vessels
and helicopters to attempt

to see if there were
any people, any survivors,

and no survivors were found.

♪

NARRATOR: An extensive
search of the seabed

uncovered the wreckage of the ship.

♪

NARRATOR: And crucially,
its voyage data recorder,

the equivalent of a plane's black box.

It held records of the
ship's exact location,

and audio recordings of all conversations

on the bridge in the hours
leading up to the disaster.

SULLIVAN: The last
moments of this ship are really

heart-rending, because all
the crew members have gotten

onto the railing and are
trying to get off the ship.

But there are two people
left in the wheelhouse.

There's Captain Davidson,
and there's one seaman.

♪

And as the ship lists farther
and farther to one side,

the seaman doesn't have the strength

to get to the high side of the ship.

To Captain Davidson's credit,
he stayed there

to the very last minute to try
to save the life

of this one seaman.

NARRATOR: The audio
recordings revealed their final words.

SULLIVAN:
I don't have a ladder up here.

I can't extend it down to you.

I don't have a rope to pull you up.

You are going to have to
pull yourself up to the side

of the ship in order to get out of here.

And the seaman is saying,
"Captain, I can't, I can't.

Don't leave me."

And Captain Davidson is saying,

"I'm not gonna leave you."

And he doesn't.

NARRATOR:
The sinking of the El Faro

claimed all 33 sailors' lives.

SULLIVAN: Every family
of a seaman knows that

they're involved in
a dangerous occupation.

Nobody expects that they're
going to go out to sea

and not come back.

NARRATOR:
So why did Captain Davidson sail

the El Faro straight
into hurricane Joaquin?

Audio recordings reveal confusion about

the hurricane's severity and location.

Only minor course adjustments were made.

According to the NTSB report,

the captain knew he was
sailing into a severe storm

and his crew was uncomfortable
with his decision.

SULLIVAN:
The captain and the chief mate

had a discussion about
alternate routes very early

in the voyage, and the captain
considered that

and rejected the alternative routes.

Later, at 2:00 in the morning,

the second mate, Danielle,
actually rang up the captain

who was in his cabin asleep
and suggested to him

that they needed to do something.

And the captain said it didn't
feel like it was that bad

and he went back to sleep.

[waves crashing]

The captain's attitude was one of bravado.

He said, "Look, I travel
in the Gulf of Alaska.

"I see weather and waves
like this all the time.

"And, therefore, I'm not
going to be concerned,

and you shouldn't be either."

NARRATOR: The crew
may choose to raise concerns,

but the captain's decision
is always final.

Could this be what
happened on the Ever Given?

Did the captain simply make a bad decision

that led to the accident?

After freeing the Ever Given,
the Canal Authority tows

the ship to the appropriately
named Great Bitter Lake.

Here, in a further twist,

the Egyptian authorities
place the ship under arrest.

It can go no further
until the Canal Authority

and the ship owners conclude negotiations

to determine who will pay
for the salvage operation.

The Egyptians leveled an
initial claim against Ever Given

of 916 million U.S. dollars.

[speaking Arabic]

[translated]: We were
negotiating with the owners

to get back the losses
we incurred at least.

[speaking Arabic]

NARRATOR: It is terrible news
for those with cargo on board.

The case ends up in the Egyptian courts.

Here, the ship owners produce transcripts

of the audio recordings
from the ship's bridge,

as well as a detailed
timeline and accident report,

drawn up by a respected maritime expert.

They say that in the moments
leading up to the crash,

the maritime pilots,

who were on board to guide the
Ever Given through the canal,

were navigating the vessel.

♪

♪

To understand events on
the Ever Given's bridge,

first we need to understand

what happens when a maritime
pilot boards a ship.

[ship horn blaring]

Greg Tylawsky was a
San Francisco Bar pilot

for ten years and regularly

piloted ships the size of the Ever Given.

♪

In a normal situation, I board the ship,

I have an exchange with a
master on what the plan

for my routing will be.

Once he's comfortable with the plan,

or she's comfortable with the plan,

and I'm comfortable with the situation

on board the vessel, the pilot assumes

navigational control of the vessel.

[indistinct chatter]

They're going to control the heading,

the speed, the direction,

and the communication protocols.

NARRATOR: Pilots don't
steer the ship themselves;

they issue commands to the
other officers on the bridge.

To the helmsman,
who controls the direction

of the ship with the rudder.

Starboard Ten. Starboard Ten.

NARRATOR:
And the bridge watch officer,

who controls the speed of
the ship with the throttle.

[indistinct chatter]

The standard for pilots,
really, around the world,

is that the commands
from pilots are direct

to the person who has their
hands on the steering wheel,

and they're direct to
the person that's standing

next to the throttle for the main engine.

NARRATOR: Pilots have performed
this task for hundreds of years,

as they have detailed local knowledge

of ports and narrow crossings

that the captain, the master
of the ship, does not.

But even though the pilot takes
charge of navigating the ship,

the captain is still responsible
for the ship's safety.

[speaking indistinctly]

TYLAWSKI:
It's the master's duty

to intervene at a point
where it is obvious

that the pilot is in
some way incapacitated,

or is in some way dangerous

to himself or to the vessel.

Starboard 15.

PEKCAN:
The relationship between a pilot

and the captain and his team
on a ship can be very tricky.

The bridge team will not necessarily

have ever met this person before,

yet they have to give control
of their vessel to him.

NARRATOR:
In this scenario,

miscommunication can end in disaster,

and has in the past.

♪

On November 7, 2007,

the Cosco Busan, a cargo ship loaded

with more than 2,500 containers

was leaving the San Francisco Bay

en route for Busan, South Korea.

As the ship's pilot navigated the vessel

towards the Bay Bridge,

thick fog covered the water.

TYLAWSKI:
On that morning,

I recall driving across the Bay Bridge

and, looking out,

the Port of Oakland was
completely immersed in fog.

NARRATOR: At the time,
Captain Greg Tylawsky

was training to become
a San Francisco Bar pilot.

TYLAWSKI: There's a
tremendous amount of wind and fog

that are prevalent in the area.

You have currents that flow into
the bay and out of the bay.

NARRATOR:
At 8:30 a.m., disaster struck.

The Cosco Busan crashed into one
of the towers of the Bay Bridge,

opening a large gash in its hull.

TYLAWSKI:
A fellow trainee

walked in and he said,

"Hey, Greg, did you hear?"

My first question to him was,

"Was there any oil
in the water?"

He said, "Yes."

NARRATOR:
53,000 gallons

of oil from the ship's fuel tanks

quickly spread around the Bay Area,

eventually contaminating nearly 26 miles

of protected coastline.

It killed more than 2,500 birds,

disrupted local fishing stocks,

and cost $70 million to clean up.

TYLAWSKI:
It was a gut punch.

We have such an
unbelievable safety record.

Something like this happening

really hit everyone very personally.

NARRATOR:
An investigation revealed that

in the dense fog, and faced with an

unfamiliar radar system,

the pilot misjudged a crucial turn.

♪

The report also found
that the pilot was taking

a number of medications
that likely reduced

his ability to safely pilot the ship.

He was taking things that would
have had a sedative effect.

So I think it's pretty safe to say

he would not be processing
information effectively.

NARRATOR:
But the report also found that

the captain was reluctant
to assert authority

over the pilot, and failed
to oversee his performance.

The report also suggested

that cultural differences
may have played a role.

TYLAWSKI:
The master

was under the impression

that it must be fine to sail the ship

because the pilot says that
we should get going.

NARRATOR: In court, the
pilot pleaded guilty to negligence.

He lost his license

and was jailed for ten months
for causing the oil spill.

♪

The incident highlights the critical role

pilots play in the safe
navigation of big ships.

And what can happen when
the captain and the pilot

don't communicate effectively.

MERCOGLIANO:
The relationship

between the master and the pilot

has to be a seamless exchange

of information and of
control of the vessel.

NARRATOR: Is it possible
that poor communication

between the captain and pilot contributed

to the Ever Given accident?

♪

The findings of the
official investigations

have not yet been released.

According to the Suez Canal Authority,

it was a complex accident
with two main factors at play.

[translated]:
The biggest factors were

the weather conditions
and personal mistakes

made by the captain.

The captain was unable
to control the ship,

especially because he
was going at a high speed,

which was a mistake.

NARRATOR: They also blame
the captain's use of the rudder.

[translated]:
He was using the rudder

in the wrong way; he kept
changing direction too fast.

NARRATOR: Both the
owners and the operators

of the Ever Given
declined to be interviewed.

But in court, the ship
owners stated that it

was the marine pilots who
ordered the increase in speed,

and controlled the direction of the ship.

By analyzing transcripts
of the audio recordings,

and the report commissioned
by the ship owners,

experts can piece together a hypothesis

of how the ship came to be going so fast,

and why it crashed.

♪

As the Ever Given approached the canal,

the report says that strong variable winds

made the ship hard to control.

MERCOGLIANO: One of the
questions that needs to be asked

is whether or not the Suez Canal Authority

or the vessel's master
should have not made

the passage through the canal.

♪

NARRATOR:
At 7:18 a.m.,

at the entrance of the canal,

the ship veered close to the left bank.

According to the report,
the pilot then ordered

"additional full speed ahead"

to increase the vessel's speed.

TYLAWSKI: This is a way
to regain maneuverability,

to increase that resistance
to the wind forces.

NARRATOR: The transcripts
suggest the maritime pilot ordered

the rudder hard left and hard
right in quick succession.

What appears to have happened was

the situation began to degrade.

The vessel was maneuvering in the channel.

It was starting to lose control.

NARRATOR:
At 7:36,

the report states that the wind
rose to 48 miles per hour,

making the vessel even
more difficult to control.

Bank effect dragged the vessel from

one side of the canal to the other.

The ship had now increased
speed to over 13 knots.

TYLAWSKI: Increasing
speed increases inertia,

so that if you need to do another

corrective motion later on,
guess what you have to do?

You have to increase the speed even more.

And now you're in a losing battle,

because every time you
increase that speed,

you reduce your ability
to get out of trouble.

[loud thudding]

NARRATOR:
According to the report,

many different factors
played a part in the crash,

including weather, the ship's high speed,

and the extreme rudder orders.

The Canal Authority say

that the pilots are not to blame.

RABIE [translated]:
The instructions being given

by the pilots to the
captain are for guidance.

At the end of the day, it's the
captain's responsibility.

He can choose whether or not
he follows the pilot's advice.

♪

NARRATOR: Legally, the
captain is always responsible

for the safety of the ship.

But in practice, it's very rare

for a captain to overrule their pilot.

Questions remain about the decision making

and communication on the bridge.

MERCOGLIANO: If a master
has a question regarding a pilot,

it's within his authority to immediately,

without question,
assume command of the vessel.

But the implications are,

should an accident befall that vessel,

the master, by relieving the pilot,

has taken upon himself
the full responsibility

for whatever happens on the ship.

It also could create a potential problem

in the future should that vessel come into

that harbor and have to use pilots

from that same association.

♪

NARRATOR: After a
trial in the Egyptian courts,

the canal authority
and the ship owners reached

a settlement for an undisclosed sum.

♪

The Ever Given was finally
allowed to continue its journey,

more than 100 days after the crash.

It arrived in the Netherlands on July 29th

and in England the following week,

four months late.

This six-day blockage of the Suez Canal

held up an estimated $58 billion of cargo,

reportedly cost Egypt up to $90 million

in lost revenue,

and reduced annual world trade growth.

♪

In Egypt, the Canal Authority

is extending a second lane farther south,

and widening key sections of the waterway,

to make the route safer for large ships.

RABIE [translated]:
We're on track

and we'll hopefully finish in two years.

NARRATOR:
But the accident has highlighted

the vulnerability of
international shipping,

and the fragility of
our global supply chain.

MERCOGLIANO: We have not
kept up with the safety measures

that really need to ensure that accidents

similar to the ones we've seen

are prevented in the future.

It's too easy for things to go
catastrophically wrong.

SULLIVAN: The Ever Given
was, I think, a wakeup call

to everybody of the fact that

you're going to have
bigger and bigger ships.

You're more reliant on fewer
ships with more containers.

And if those ships don't arrive,
you can shut down an economy.

And I think if you didn't get the message

from the Ever Given,
you weren't paying attention.
