Departure

- Previously on Departure. - Moses...

- Who's Moses? - I want an assurance

that the name Hassan Esmaili will stay secret.

Did you find anything on Hoffman?

He was the man in the raft and Hoffman did work in aviation.

We were safety consultants, part of various red teams

that tested for aircraft vulnerabilities.

Kendra! I'm sorry. I screwed up.

- They're after me. - AJ?

I know this is hard, but you'll need to step away.

Everyone, by now you've all heard

about Kendra. Levi will take her place.

Do they know how our call was recorded?

Apparently, it was Malley's son.

I sent a Trojan to one of your email groups.

You clicked on the bloody attachment.

British Global Air has never, and will never,

- compromise on safety. - You world class bullshitter.

- That's Hassan Esmaili... - Bloody Mossad agent.

What's he doing in the captain's seat?

Why did you leak this without consulting me?

Did you even try to think through the consequences?

- You broke our deal. - Not me.

- Janet Freeh. - If the man in the cockpit

is identified as Hassan Esmaili then operations will be exposed

and lives put at risk. Janet promised us

- she'd keep this under wraps. - I know. She's desperate.

- Why? - MI5 must know

that the black box data will debunk any sort

of pilot suicide theory. Now they're trying

- to shift the blame to Hassan. - Terrorism is the public's worst fear.

MI5 can take over and trust me,

they'll handle it.

like you handled the flight simulator?

Or, your surprise witness, Mister Littlefield?

You were supposed to control your team, Howard.

We wouldn't be having this conversation

if you'd stopped them from finding the black boxes.

We have no idea what's on those black boxes.

There's no clue that they will support terrorism.

It's your job to make it fit, Howard.

I had Janet leak the photo.

An Iranian pilot bringing down a British airliner?

Do you want to start a bloody war?

That's not our concern here. We need you to build

a credible terrorism case. It's in our best interests

to offload to MI5.

They have a history of discretion.

If you'll excuse me.

Weak link.

Why would we help you?

Look, people went to great lengths to cover up

what crashed Flight 716. Now they'll use Hassan

to bury the truth, even if it costs your agents' lives.

We'll keep an eye on her.

Well done, Nadia!

You've truly gone above and beyond.

Theo ready these for data collection.

- Yeah. - You must be exhausted.

- No! Howard, I'm fi... - But don't-don't worry.

He'll-he'll handle it. He'll handle it. You rest.

It's okay. Good job.

- Thanks. - Alright.

So, are they functioning?

They're still drying. Some of the connections

are definitely corroded, so, could affect the audio.

Will you hook it up for a test, please?

Well, it's-it's still too soon to...

Just a wee one.

Okay.

Flaps. Two sets, two indicated.

Two sets, two indicated. Check.

That's at JFK just before takeoff.

Well done.

Thank you.

Good. Good.

Ladies and gentlemen,

this is your co-pilot Arthur Delaney.

Please ensure that your electronic devices

are turned off as we prepare for departure.

Thank you and enjoy your flight

Do you have your phone?

What's wrong?

We need to call Kendra.

Hello?

- Moses isn't a person. - What?

It's a thing.

A thing...

M-O-S-I-S.

- MOSIS. It's an acronym. - For what?

I don't know but Maddy said Hoffman kept saying:

"MOSIS did it." Could he have meant software,

or some sort of virus that he planted?

Maybe. But she also said Hoffman was panicked, afraid.

Doesn't really vibe with someone who's trying

- to crash a plane. - True.

Look, I'm going to circle back to Stefon Tark at King's

and see what he knows about this MOSIS. Meet you there?

I can't. Got to stay here at Scotland Yard.

I've shown them the evidence that Derek Strong was murdered,

but it's going to take a damn sight more convincing

to get them to investigate 255 aeroplane passengers.

- Got it. Keep me posted, yeah? - Kendra, wait!

Yeah?

They've pulled a body out of the Thames last night.

- What? - Our orderly.

The same man who tried to kill you and A.J.

I think they're trying to snip off all the loose ends.

I've arranged for police protection of A.J.

You need to let me do the same for you.

Yeah. Of course.

You stay safe.

We have had to endure the outrageous speculation

that the man we loved intentionally

crashed Flight 716. We never believed

he was capable of such an evil and cowardly act.

And with the publication of this photo,

the rest of the world now knows, too.

- Mister Tark? - Ms. Malley.

So why didn't you tell me about MOSIS?

I haven't heard that name in years. I'm sorry,

- I didn't think it... - It's an acronym.

- What does it stand for? - Multi-user...

Onboard Smart Interface System.

It was BGA's in-house build.

The airline wanted proprietary rights

- over the software. - Okay. And-and what does it do?

MOSIS was an impressive programme.

It provided the basis for the current in-flight entertainment system.

I think they call it, 'NAVI' now?

Hey.

- What'd you want to show me? - This.

- You're a gamer? - Yes. And so was Hoffman.

Actually, the only online presence we found

- was his gamer name HoffMaster69. - Right.

But, when his flat was searched,

no gaming console was found on the inventory list.

- Janet could have destroyed it. - That's what I thought.

But then I decided to follow him anyways.

What? He's online? Hoffman?

Yeah.

Hey. You've got impeccable timing.

I'm putting you on speaker.

MOSIS is Multi-user Onboard Smart Interface System.

I think that Hoffman found some kind of vulnerability

- and the airline shut him down. - Kendra,

Hoffman's avatar is active right now.

- What? - If Hoffman were arguing

with BGA over a vulnerability in the aircraft's system,

he must have backed up his findings somewhere

and consoles contain pretty massive hard drives.

All right, well, then we need to find that. Coordinate with Dom.

I've lost control!

Let me in!

There's all kinds of interference in the audio

and these are the only clear segments so far.

I'm in control! I've deployed the spoiler.

Allahu Akbar! Allahu Akbar!

Allahu Akbar!

Allahu Akbar... The Jihadist war cry.

It's a... it's a prayer. I think it means

- "God is greater". - It was Hassan all along.

Um, I-I think we need to run electronic filtering to try

- and recover the missing audio. - The evidence

is too compelling, Levi.

You'd do well to get on board.

- Keep him engaged. We're close. - I'm trying to.

- We've got him! - Where is he?

- Sending the address now. - Here, let me take over.

Yeah, yeah.

What have you got, Nadia?

The I.P. address is coming

from an apartment on Ringstone Court.

Isn't that where Hoffman lived?

Yes. But it's coming from a different flat. 409.

Okay. Well, look, um... I'm near there now.

Um, I'll meet you there, okay? Thanks. Change of plan!

Can you take me to Ringstone Court, please?

What's that address again?

Ringstone Court.

Hi. Just you in there?

It's not really your business, is it?

Where'd you get that console?

- The shop. - That's funny.

'Cause your neighbour, Mr. Hoffman, reported it stolen.

- You a cop? - No.

But a lot of my friends are.

We used to play games together.

I told my mum he let me borrow the console.

- How'd you get it? - Spare key.

My Mum's the porter here.

Where is he, Mr. Hoffman?

Here. Why don't you pull up the menu?

Okay.

It's got nothing to do with the game.

Just old rubbish, really.

Yeah?

Well, it's worth something to me. Thanks.

Why couldn't you have just gone along with it?

I know all about Howard and you.
