(beeping)

Hey, Charlie.

Find anything
you can help us with?

Yeah.

These cases won't benefit
from mathematical applications.

Although, we could approach
all these with Chaos Theory.

Yeah. Chaos I got.

Right, but with chaos,
there's no telling where a case will lead,

and there could be mathematical
applications I can't detect yet.

I love that about you.

What?

You never give up, do you?

Well, there's always
a solution, Don.

You know, if there's
any limitation, it's got to be

in the mathematician,
not the math.

How about fun, Charlie?

What do you ever do for fun?

Well, if you must
know, Dad thought

playing golf was something we
might enjoy doing together.

I'm sure he did.

You know he's like
an eight handicap, right?

I'm a pretty quick study.

Just don't let him talk you
into betting.

Last time we played,
he took me for 20 bucks.

Hey.

DON:
What's up?

In the last ten minutes,

the FAA's received
seven eyewitness reports

of an unidentified
object flying low

over the San Fernando Valley
headed toward Los Angeles.

What about a radar signature?

That's just it.

The object's not showing up
on either civilian or military radar.

Edwards Airforce Base is
scrambling two F-16s for an overflight.

Sounds serious.

Homeland Security's
been warning about

a small craft terrorist
attack for months.

No flight plan, no contact
with air traffic control.

We have to assume
this craft is hostile.

What about you taking the sightings
and trying to plot a flight path?

Oh, well, I...

Just give it a try.

If he does it,
patch him through to me.

Okay. Where you going?

I'm gonna go up to the roof,
see if see anything.

Contact Homeland Security.

See if they have
a military attaché in the area.

I want to monitor their com.

- Agent Eppes?
- Yes, sir.

- Anything yet?
- Nothing.

PILOT:
Military ATC, this is Rogue One

at Echo Delta Tango four, four,
niner and descending.

That's our two F-16s coming in.

ATC: Rogue One, you are cleared
as assigned.

Make best time on target.

Hey, Charlie,
what do you got for me?

You got anything?

Based on these sightings,

the object should be over
Glendale on heading 1-1-8.

Glendale.

( man laughing )

( indistinct chatter )

MAN:
Did you see that?

You got it? Are you sure?

New LAPD sighting one mile north
of the Silver Lake Reservoir.

Don, based on this new sighting,

I estimate the object is on a direct
course for downtown Los Angeles.

Downtown? Are you sure?

Yeah, if these reports
are right.

Military Air Traffic Control,
this is Leader One.

Direct Rogues One and Two

on a direct heading
to downtown Los Angeles.

ATC:
Roger that, Leader One.

PILOT: ATC, this is Rogue One
and Two on new heading.

Nose is warm, visuals are clear,
weapon systems are hot.

Pinging on PRF.
All frequencies.

Charlie, I don't see anything.

Look, according
to my calculations,

it should be just north
of downtown.

It's got to be right there.

( loud whooshing )

PILOT: Rogue One checking
one-zero, one-one and one-two.

Negative contact.

PILOT 2: Rogue Two, checking
one, two and three.

No Joy. Repeat, no joy.

Where the hell is it?

ATC:
Echo Delta Tango.

Night sky clean and clear.

Rogue One, this is Leader One.

Confirm your visual.

PILOT 1:
Roger, Leader One.

That's a negative.

Whatever you boys were chasing,
sir, it's gone.

(whooshing)

( echoing ):
We all use math every day...

to predict weather...

to tell time...

to handle money.

Math is more than formulas and
equations.

It's logic.

It's rationality.

It's using your mind to solve
the biggest mysteries we know.

It's over here.

Came right over those trees.

DAVID: How long
it take to pass by?

Uh, five, ten seconds, maybe.

Not very fast.

How high you think it was?

Few hundred feet.

Yeah? What did
it look like?

Dark, lights all around.

I have a video.

- My wife shot it.
- You have a video?

It's not great.

- We still need to see it.
- Sure.

We'll get it back to you.

( sighs )

Man, I was hoping it was
some idiot in a Cessna

getting his pilot's license,
you know?

Altitude, speed,
path toward downtown.

Could have been the practice run
for a terror strike.

Test our responses?

Maybe.

Like I said, it's not great.

There. There it is...

All right, wait...

Just freeze it.

Yeah, he was right.

- It's not great.
- Uh-uh.

- I don't know...
- Agent Eppes?

Yeah.

Hi. Erica Weston. National
Transportation Safety Board.

Oh, hey Erica. Don.

- Hi, Don.
- David Sinclair.

- David.
- Thanks for coming.

Not a problem.

Post 9/11,
U-A-E's are a top priority.

U-A-Es?

Unexplained Aerial Events.

Your seven sightings --
they're all consistent with this?

Yeah, pretty much.

We might be looking at an MPH.

Not a U-A-E?

Sorry.
Occupational hazard.

Multi-Person Hoax.

Yeah, I don't know.

I mean, it seems
pretty elaborate to be a prank.

17 years ago in Michigan,

eight ultralites flew
in formation at night

to create the appearance
of a UFO.

Well, I don't want
to assume it's a hoax.

I mean, we need to find out where
it came from and where it went.

I'm thinking maybe
Charlie might be helpful.

That was better.

- What?
- It was.

You almost hit the ball.

You know, I'm-I'm the king
at basketball,

I-I can snowboard,

I'm the best at video games,

I'm even getting over my fear of
rock climbing,

but I still... I can't hit
this little white ball.

Because you're lifting up.

You're trying to find out
where the ball is going.

Now all you have to do
is just trust your instincts

and let me watch for the ball.

- Go ahead.
- All right.

All right,
that was... better.

I stink.

Charlie, do you always have
to excel at what you do?

This shouldn't be happening.

I've worked these numbers.

Hey, come on,
this is what is known as fun.

Out here together in the...
in the fresh air.

- Isn't that enough?
- Don't get me wrong.

It's not like I'm not enjoying
myself with you, Dad.

It's just, I'm just surprised the
math isn't giving me an edge.

Yeah. All right,
now you just...

watch and learn.

Now you sit down

like you're on a stick, hmm?

And let your hands
work together.

Draw the club back slowly.

- Huh?
- Awesome.

- That was good.
- See? There's no math involved.

It's all rhythm.

( cell phone rings )
It's just... rhythm.

Oh, rhythm.

There's a rule on the course
about cell phones, you know.

Yeah, I know. Hey, Don.

Hey, what's up?

Yeah, you got it.

Okay, bye.

CHARLIE:
Hey, sorry I'm late.

Dad wanted to walk.

Took us a little longer to get back
to the clubhouse than I'd estimated.

It's okay. Charlie, this is
Erica Weston from the NTSB.

She specializes
in what they call

Unidentified Aerial Events.

Hi. Pleasure.
Nice meeting you.

Hi. Likewise.
You're right on time.

Your student just finished
loading our radar images.

CHARLIE: This is
Civilian Air Traffic Control?

ERICA: Right.

These blips are
commercial airliners.

The others are small planes,
but over here,

where our bogey was,
there's nothing.

Hmm. What do you think?

Well, there's a lot
of noise in the system.

Hmm. What about
trying the noisy edge?

- Mm-hmm.
- DON: What's that?

AMITA: Well, there's random noise
in every radar system.

And sometimes the signals
the radar's designed

to pick up are so weak,

they're obscured by the noise.

Here. Listen.

( hissing )

CHARLIE: That noise you're
hearing

is really the noise
of the system.

Without a signal,
all we're hearing is random energy.

ERICA: How do you
find signals that faint?

It's called Squish/Squash.

It's a technique that was
developed by a mathematician

from the University of Alberta
in Canada.

Looks for anything
that looks like a-a weak signal,

and then mathematically
squishes and squashes that data

to guess at its speed
and at its direction.

How is that possible?

Okay, imagine a...

Imagine a room full
of-of 20 or, um,

or 30 people clapping.

Now some people clap loud,
some soft.

Most generally at the same pace.

Now imagine a woman
in that audience

clapping much, much slower,

clapping at
a very specific rhythm.

Her rhythmic clap is
the signal we want to track.

But we can't. We can't hear it
amongst the random clapping.

The signal's lost in the noise.

However, Squish/Squash allows us

to isolate the rhythmic clap
and track it.

DON: So with that, you can
pinpoint the flight path?

Where it started
and where it ended?

Probably.

And how long would that take?

Oh, it's hard to say right now.

Well, I mean, if we're dealing
with terrorists,

and they make another run,
Charlie...

Right.

Well, Larry has time booked
in the computer lab.

I mean, that could help us
run this program much faster.

Call Larry.

When you first told me
you wanted to run an advanced

conditional probability
distribution application,

I was delighted.

Naturally, I assumed

we were about to attempt a model
of my theory

concerning the distribution
of gravity waves.

I'm sorry, Larry.

But no, little did I realize
my slender budgetary resources

were being used to
finance a UFO hunt.

Well, I think the more accurate
term is Unexplained Aerial Event.

Right, and-and you know I'll get
the FBI to reimburse you, I promise.

Oh, I-I suppose national
security has to take priority.

Yes. Thank you for
being understanding.

You say this craft
left no radar signature?

Nothing visible.

So, what assumptions
are we making

for the program you're running?

Well, the FBI has eliminated
weather balloons.

They've eliminated
ultralite aircraft,

helicopters and military drones.

Which leaves us...?

I think the highest probability
is that it's some kind of small,

piloted aircraft that was flying
without a radar transponder,

or one that was turned off.

Well,

keep in mind,
quantum physics maintains

an infinite number
of possibilities.

This might have nothing to do
with man or machine.

Oh, this could be some sort
of inter-dimensional event or...

Yes, it might even be a vehicle
from another part of the universe

using a type of propulsion we
can't even begin to understand.

Okay, Larry.

We'll try and factor that in, as well.

LARRY: Okay, you two,
you make your little jokes.

The fact remains,

we may not be alone.

( computer beeping )

What-What's that?

That's the Squish/Squash program
calculating the object's likely flight path.

LARRY: Well, it looks like the flight
path of our mysterious little object

is suddenly becoming
a lot less mysterious.

CHARLIE: This is the path of the
object as calculated

by the Squish/Sguash algorithms.

ERICA:
And what happens here?

The signal becomes too thin
to track.

DON: What, right around the time
it reaches downtown?

Right, but

if we follow the projection
of the data,

the flight takes us
over the city.

Now, where's that on the map?

That is right over
the Staples Center.

ERICA:
Or right into it.

Major sports venue,
thousands of innocents.

Exactly the kind
of high visibility

soft target we've
been worried about.

Why don't you get a schedule of
upcoming events at the Staples Center?

All right.

So, what we have
is a small aircraft

capable of penetrating densely
populated areas without detection.

Obvious dangers are is
if it crashes into a building

or God forbid
disseminates a WMD.

Ms. Weston has the,
the good news.

We now believe we know the
location of the flight's origination.

According to Professor Eppes,

craft took off
from somewhere in here.

What I'm calling
the "area of origin."

And assuming we're looking
for a fixed-wing airplane,

it would need a runway
to take off from.

How many strips are
in the area of origin?

One commercial, four
recreational airfields.

We need to cover them all.

I mean, track every single plane
that took off that night.

Talk to as many pilots
as possible.

I mean, somebody
had to see the thing.

- All right.
- Okay, let's do it.

Okay let's go.

I don't get it. The aircraft
should have originated

from an airfield
that the FBI checked out.

You know, here's where I get
reductive on your ass,

'cause you keep
saying "aircraft,"

but so far,
no one's been able to identify

whatever it was that people saw.

What are you saying, Larry?

I'm saying instead of
building a flight path,

let's try focusing
on the object itself?

You know what?

He's right.

We could get a visual
of the object

by building in all the radar
sources at the same time

yes, civilian and military.

- So... overlap the radar sources?
- That's right.

By layering the images, we could build
a three-dimensional cross-section of it...

( typing )

( beeping )

There.

Now it's working off of
all seven radar sources.

And it's building
an image of the object.

( blipping )

( blipping continues )

Charlie?

Is that what I think it is?

Now, le-let's
be very, very careful.

We shouldn't jump to any
conclusions or make any assumptions.

There could be any number
of reasons why that looks like...

A vehicle from another part
of the universe.

I mean, sure, it looks
like a real UFO.

We don't know
what a UFO looks like.

How can you say
this looks like a real one?

It's cutting-edge
aeronautical design,

but it was definitely
made here on Earth.

Well, that's good,
'cause I really like my job, you know?

ERICA: This is similar to the
blended wing design.

You know, the same one used
to create the B2 bomber.

It's a concept, actually,
that dates back to 1939,

when Lyle Farver proposed it
to the U.S. Army Air Corps

for a 500-miles-
per-hour fighter.

Something this small?
Pretty radical concept.

Since we were looking for
a fixed-wing aircraft,

naturally we're looking for an
airstrip where the flight originated.

Right, but we didn't find any.

Which forced us
to consider alternatives.

Freeways, makeshift runways.

Only any of those
would have had a witness.

Which is why we have to ask
ourselves a whole different question.

Why assume that this aircraft
needs a runway at all?

Vertical takeoff?

Like one of those, uh,
Harrier jets?

Yeah, only smaller and lighter.

And that would minimize the
power it would need for sufficient lift.

Which would explain
why no one heard it.

All right, so,
it takes off straight up and it's quiet.

How does that explain
it not showing up on any radar?

Well, there's only one
explanation, really.

It'd be construction material.

Some lightweight
non-metallic composite

that radar wouldn't pick up.

And who makes a plane like that?

Something like this
can't be done overnight.

This is the kind of plan that
would take years in the making.

Well, still, it's got to be a
relatively small community, right?

I would start
with Nordell Aeronautics.

Nordell?

They've been offering
a $5 million prize

for a working craft that has
vertical takeoff for years now.

We've offered
the prize since '97.

No takers?

No winners.

Vertical takeoff's proven
to be a tough nut to crack

in the field of personal
aircraft.

Personal aircraft?

Some people believe

that once vertical technology's
actually conquered,

affordable and
easy-to-fly aircraft

will eventually replace
the automobile.

I'll tell you,
if this thing really flew,

I'd sure love to talk
to the team behind it.

Yeah, well, so would we.

We were hoping
you might be able to tell us

who'd be capable of putting
a plane like this in the air.

Just a handful of designers,
I can tell you that much.

Anyone out on the west coast?

There's a couple of
engineers that come to mind:

David Croft and Lane Gosnell.

How much do you know about them?

Croft and Gosnell
used to be partners,

until they had a falling out.

Over what?

The direction of the design.

MAN: You're saying
this thing actually flew?

At least 50 miles.

At heights varying from several
hundred feet to a few thousand.

This photo
what Gosnell gave you,

or did you actually see it fly?

Gosnell. You mean Lane Gosnell,
your former partner?

Well, this is his plane,
isn't it?

Is it?

Unless someone else
stole this wing design from me.

We understand that you and
Mr. Gosnell had some sort of dispute.

You might say that.

We were told it was about
the design of this aircraft.

The design had nothing
to do with it.

It was about Lane.

And his, uh,

obsession to be remembered.

You see, with Lane,

it was all about
making a statement.

Showing the world that the rules
didn't apply to him.

Not even the rules of physics.

Frankly, it didn't matter
how dangerous it was

or who might get hurt
by him doing it.

Mr. Croft, do you have any
idea where Lane Gosnell is now?

Not a clue.

But when you find him,

you tell him my lawyers are
gonna be talking to his lawyers.

( typing )

Hey.

Lane Gosnell.

Two years ago, at a conference
on air traffic safety in Seattle,

he gives a presentation in
which he claims the 9/11 hijackers

would someday be viewed
as pioneers in aviation.

He what?

He said the flights into the Towers
proved that the average person

was capable of piloting an aircraft
with a minimal amount of training.

That's twisted.

Twice he flew a Cessna into
restricted military airspace.

Twice he had to be escorted out
by U.S. warplanes.

Claimed he did this
in protest of news blackouts

of returning casualties
from Iraq.

Don, why haven't we
locked this guy up?

Oh, we did. He was held for
observation for three weeks,

and he was supposed to undergo
psychiatric counseling.

- What happened?
- He didn't show.

We got us an
emotionally disturbed man

trying to make aviation history.

MAN ( mutters ):
You believe this?

ALAN:
Still can't find it?

No.

ALAN: Why don't we just drop
another ball?

'Cause it has to be here.

The ball was traveling
on a trajectory

whose endpoint would put
it in this immediate area.

Charlie, there's one thing you
got to learn about this game.

Golf balls don't always
do what you expect them to.

Yeah, well, golf balls have
to follow the rules of physics!

Just like any other object.

Then why do people
keep losing so many of them?

Chaos.

Why don't we let this foursome
play through?

In a minute.

GOLFER:
We don't have all day!

Now where you going?

Well, there's no reason to think
the ball landed here.

So it's where I'm looking,

because it doesn't make sense.

It's where I don't expect it.

Eh...

Here it is.

Except that's not your ball.

- GOLFER: Let's go, guys.
- What?

Uh, found it!

Come on, let's go.

You can drop the ball over here.

Well, he hasn't been home
in a couple of days.

Uh, he's been working.

When was the last time
you talked to him?

Few days ago.

What's this all about?

Do you recognize this aircraft?

Where'd you get this?

So you recognize it?

Yeah, I mean, it's
my dad's plane,

but he didn't want
anybody else seeing it.

Maybe he shouldn't have
flown it over Los Angeles, then.

Flown it?

What are you talking about?

That image was captured
on radar two nights ago.

- No.
- Yeah.

Well, that's not possible.

Well, your father's plane was
tracked flying at low altitudes

in populated areas with no
flight plan and no radio contact.

If you have any idea
what he was planning, Blake,

and you withhold
information from us,

you're looking at
a serious felony here.

Blake we need to talk
to your father right away.

Okay, yeah, sure.

I mean, he's at his workshop,

but I'm telling you,
the plane is there.

Where's his workshop?

( dog barking )

That's his truck,
so he should be here.

Hey, Dad!

Dad, you in there?

Don, it's the same plane.

BLAKE: It's supposed to be here.

This is not possible.

DON:
Hey! Hey!

Hey!

It's the exhaust from
the vertical engines.

It must've burnt the grass.

So he did fly it, then?

Yeah, I guess so.

And where would he take it?

I don't know.
I-I have no idea.

Just because
he's an antiwar activist

doesn't make him a criminal.

Maybe not, but we're also aware
of his psychiatric history.

As well as his feelings about
the United States government.

He's not a violent person.

He would never do anything
to intentionally harm someone.

Why didn't he tell you
about the flight that night?

You don't know
his intentions, Blake.

A lot of innocent
people could be hurt.

You understand what I'm saying?

He wasn't supposed to fly it.

Not yet. We-we were
still testing the rudder.

So he talked to you about it?

No. Something must've happened.

What do you mean?
What, a crash?

No, no.

He's much too good of a pilot
for that.

Then what?

You have to understand,

my father's in a race
for the history books.

- Uh-huh.
- Okay?

An obsession like that
makes you do things

that-that you wouldn't,
and that you normally couldn't.

What? Like what?

What he's doing is very
expensive.

Uh-huh.

The materials, the tests,
the designs.

We don't have
that type of money.

So, where'd the money
for all this come from?

He sold an interest in his plane
to a venture capital firm.

Which one?

Ridenauer Investments.

It's a German company.

He was never happy
with the arrangement.

He always thought that they were
less interested in the history books

and more interested in what
the technology might do for them.

According to corporate records,

your company has put almost

$1.7 million
into Gosnell's work so far.

What can I say?

We're a venture capital firm
who just got bit by the bug.

The promise of the mass
production of personal aircraft.

Right. But it doesn't
look like your investors

have much to show for it.

Better a few years too early,
then a few too late, ja?

Besides, if Mr. Gosnell ever
gets his plane up in the air,

our share of the prize
offered by Nordell Aeronautics

more than makes for a very good
hedge on our investment, no?

Gosnell already got his plane
in the air.

What are you talking about?

The unidentified aircraft
that was recently in the news.

The one spotted
over downtown Los Angeles.

You didn't know how far along
he was with his project.

Uh, Gosnell began refusing us
any access to his workshop

over three months ago.

Which means you knew where
his workshop was located, then?

I also noticed the source of your
investments come from overseas.

What difference does that make?

Well, I was just wondering
if your motivation

is less the production
of personal aircraft

and more the sale of Gosnell's
technology to your foreign investors.

I have no idea
what you're talking about.

Mr. Ridenauer, if this plane
is used to harm anyone,

you will find yourself
facing serious charges.

- There were rumors.
- What sort of rumors?

That Gosnell was getting very
close to creating a working prototype.

But he wasn't
letting anyone see it.

And naturally, you felt
obligated to pass

that information along
to your foreign investors.

Amita... you know, I didn't
think you could make this work.

But you've come up with a novel
approach to solve this problem.

Spent six months getting nowhere
until I thought...

if you can't
come in the front door,

climb through a window.

( laughs )

Well, you've obviously,
certainly,

come a long way in
your thesis work.

Thank you.

You know what
the weird thing is?

What's that?

Well, I realized how much I
enjoy being here at CalSci.

That's good.
I'm glad to hear that.

Well, I was hoping
you'd say that, because

I'm seriously considering
getting a second PhD.

In astrophysics.

No. Don't do that.

Don't tell me I've been working with
you for over two years on combinatorics,

and you're just going to throw
that all away for physics.

Charlie, astrophysics and computer
science make a pretty good match.

- Mm.
- Besides,

I've really realized
how much I like being here.

So you'd do your work here?

Of course,
I'd have a different advisor.

Of course.

Which means that I wouldn't
be your student anymore.

I guess that's true, isn't it?

ERICA:
Dr. Eppes.

I'd like... Uh, sorry.

Is this a bad time?

No. No, no, no,
not anymore.

What's up?
What have you got?

We found the location
where the plane took off from,

and we have a suspect.

But we haven't been able
to find him or the plane.

Also, your brother thinks that
this man may not be in this alone.

Really?

There were foreign investors
in Gosnell's aircraft,

so there's a possibility
this technology

could end up in the
hands of a country

that's hostile
towards the United States.

What's this?

Weather radar of the Los Angeles
area the night the plane disappeared.

Weather radar?

We know that the plane
wasn't picked up

by conventional
air traffic radar.

Probably because
the material it was made out of

didn't have enough metal in it.

And that's what traditional radars
are designed to pick up -- metal.

Right, 'cause that's what
most airplanes are made of.

But the weather radar will show
us locations of cloud formations,

because it's tuned
to detect water vapor.

So, by re-tuning
the radar signal...

We might be able to track
the path of the plane.

Because this time, the radar
won't be looking for vapor or metal.

It'll be looking
for something in between.

I called the State Department
with a list of Ridenauer's investors.

They're trying to track down
their whereabouts right now,

see if any of them
are in the country.

- All right, that sounds good.
- Don.

- We found it.
- What, the plane?

We re-tuned radar to look
for nonmetallic materials.

We found a new flight path.

- We know where the plane went.
- Where?

Should be within a
quarter-mile area in Signal Hill.

- Right.
- Okay. Let's go.

Get on the phone to LAPD.

Tell them we need
Search and Rescue teams.

I'm on it.

( helicopter blades whirring)

( officer speaking
indistinctly )

No sign of Gosnell or the plane.

Charlie, I mean,
are you sure about the location?

- The math is right.
- All right.

I mean, I'll see if I can get
some more people out here, but...

Well, maybe we should be
considering the possibility

that the plane might be hidden
in plain sight.

How do you mean?

Kind of like
the Gary DeVore case.

Oh, yeah. This guy that just
disappeared driving back from Vegas.

Right.

And then some months later,

they find him in his car
buried under 20 feet of water.

Just yards away from where the
Highway Patrol were looking for him.

CHARLIE: Right. Gosnell's plane
could be right in front of us

yet be in an environment that's
preventing us from detecting it.

It's like Charlie said.

Look. I mean, if he went down,

here's a place it'd be pretty
hard to find any wreckage.

A junk yard.

A place already
full of wreckage.

( indistinct voices )

( machinery creaking )

Hey, guys! Over here!

She found something...

Don. It's Lane Gosnell.

He's dead.

DON:
You find anything?

Yeah, the rudder controls show
evidence of being tampered with.

- It was?
- Mm-hmm.

- Tampering? You sure?
- No question.

The box holding the rudder servo
controller was unsealed.

The mechanism was altered.

The plane went down
as a result of sabotage.

- Want me to talk to him?
- No, I got it.

Blake? All right, Blake...

Was that him?
Was that my Dad?

I'm sorry.

Can you tell me if he suffered?

We're pretty sure
he died on impact.

How does this happen?

How does something
like this happen?

Well, see, the thing is, it-it
wasn't an accident.

What?

Apparently, the rudder
was tampered with.

The rudder?

Your father was murdered.

I'm sorry.

All right, so, Lane Gosnell

was definitely killed
by an act of sabotage.

Yeah, but by who, and why?

Well, I mean, working theory has
to assume the worst, right?

I mean, it has to be because of
what that technology could do.

Just got a preliminary analysis
of Gosnell's flight data record.

Mm-hmm?

Apparently, because Gosnell
didn't know about the rudder problem,

he over-corrected,
put the craft into an uncontrolled dive.

He wasn't able to recover.

Any chance that flight recorder
can tell us where he was headed?

Not without a filed flight plan.

Most of the data on the recorder
is just pretty basic information

about changes in his
speed and altitude.

So, you can't even tell us the
Staples Center was his intended target?

You can't eliminate it, either.

Because of the sabotage,

the rudder wasn't
behaving as expected,

so we can't tell what his
true course might've been.

I mean, so, he took the plane up
for what that night? A joy ride?

Wasn't the impression I got
from his ex-partner.

Croft was pretty sure that Gosnell
intended to try something spectacular.

What do you hear
from the State Department?

So far, they've come up
empty-handed.

None of Ridenauer's investors
are in the country.

Doesn't mean they don't have
people here working on their behalf.

Hey, Charlie.

- Hey.
- What's up?

Just grading tests
for my Nonlinear Dynamics class.

Glad to see you're taking my
advice and having some fun.

Well... you don't look like
you've been having too much fun.

( sighing )
Oh, man...

this Gosnell case...

I spent all that time trying to
figure out where the plane went.

Turns out the pilot didn't even know,
because the rudder was busted.

See, that's the thing -- I got to
find out where he was headed,

'cause I think that's
why he was killed.

You got any ideas?
Anything at all?

Maybe. Could I, uh...

could I get some data
off the flight recorder?

Yeah, I mean, I can see if, uh,
Erica can drop some by.

Maybe Amita can help you out.

Dad said she's sticking around.

Did he?

Well, you happy about that?

Um... are you asking me
as her thesis advisor or...?

( chuckling )
You tell me.

Yeah, I'm happy.

Hey, what's the deal?

I thought you were
playing golf today.

Oh, no. You know, I'm really
no use on the golf course.

Charlie...

you know why he likes playing
with you, don't you?

I have no idea,
because I-I've got to be

the worst golfer
in the history of the game.

No. It's the one time
he gets to teach you something.

You understand?

That's the one time.

( phone rings )
Oh, excuse me.

- Eppes.
- Don...

the forensic report from
Gosnell's workshop just came in.

We found David Croft's
fingerprints all over the shop.

But I thought you said
he hadn't seen him in years.

And so he said.

All right, look, uh,
take a team, pick him up.

I'll meet you
at the office, okay?

You got it.

I didn't kill Lane Gosnell.

But you were pretty pissed
at him, right?

I've been pretty angry at
Lane Gosnell for over ten years.

Because he stole your design.

Is that why you led us to think he
was planning something pretty big?

All I said was
that it was in Lane's nature

to do something crazy,
and it was.

Crazier than sabotage, you mean?

I don't know
what you're talking about.

Your prints were found
in his workshop.

If you hadn't seen him in ten
years, how'd they get there?

What was it?
You couldn't let him win?

- Is that it?
- Okay, look, look,

I-I ran into Gosnell's kid
at an air show a few months ago,

and he let slip that his old man was
getting pretty close to a working aircraft.

Uh-huh.

And I had to see
that plane for myself.

Now, Lane was a great designer,

but he was an ungrateful
son of a bitch.

He just could never acknowledge
anyone's contribution.

For ten years, I worked
on that design.

So you went into his workshop?

Look, I know you think
I killed Gosnell.

I know you're thinking that.

- Yeah.
- But not this way.

I could've never touched
that airplane.

Not ever.

Don't you understand?

As much as that airplane
was Lane's,

it was mine, too.

Tell me how this works.

A servo is basically
an automatic device

used to control
large amounts of power

with small amounts of power.

What happens is the pilot moves
the flight controls,

the servo translates
those movements to the rudder.

And where was
the tampering done?

Three places: amplifier,
actuator and feedback element.

Why would somebody break
three things instead of one?

Have you considered

maybe... whomever it was...

wasn't trying to break it?

They were trying to fix it.

Don. Hey.

We think we know
who tampered with that servo.

Great. Who?

Well, we don't have a name.

What-what are you talking about?
Do you know who did it or not?

The rudder wasn't sabotage.

Right -- it wasn't sabotage

in the traditional sense
of the word.

Now, we assumed
because the plane crashed

that someone was trying
to cause it to crash,

but maybe that's wrong.

Yeah? What do you mean?

Well, what if the adjustments
were actually intended

to be design improvements?

Improvements?

But you said the flight recorder
clearly showed

that Gosnell didn't know
anyone messed with the rudder.

CHARLIE: Doesn't disprove
my theory.

It merely eliminates Gosnell

as the person
who made the improvements.

I was hoping to hear
from you guys soon.

Have you made any progress?

Actually, yes.

So do you know who did it, then?

We're still waiting
on final fingerprint analysis,

but, uh, we have
a pretty good idea.

Well, can you tell me?

Why don't you tell us, Blake?

Uh, I don't know what you mean.

See, the thing is,
I remember the look on your face

when we walked in your father's
workshop and that plane wasn't there.

And the first thing you wanted
to know at the crash site

wasn't what happened
to the plane

but was whether your father
had suffered.

You didn't have to ask
about the plane

'cause you knew why it crashed.

Whose fingerprints are we going
to find on that servo, Blake?

I was just trying
to make improvements.

That's all.

You should've told him you
changed the design, right?

- No, he wouldn't have listened.
- No?

No, I could never tell him.

He'd just remove it.

The man was so sure...

He was so sure that I could
never do the things that he could.

And you wanted to show him that you
were good enough to carry on his work,

carry on his legacy?

He wanted to be the first.

He wanted to be
the next Henry Ford.

You know what I mean?

Yeah, I think I follow you.

Do you have any idea
what it's like to live like that?

To know that your father cares
more for his accomplishments

than he does for his own son?

I mean, I wonder
if for one second,

I entered his mind that night.

I wonder if he thought that...

that I might want to be there...

to share that moment with him.

Guess I'll never know.

- Where's Chuck?
- I don't know.

Last I looked,
he was right behind us.

There he is.

CHARLIE:
Hey, Dad.

Your clubs weigh a ton.

Are you kidding? I've used
those clubs for ten years.

There's nothing wrong with them.

Dad, they're older than he is.

I don't even think
they make wood clubs anymore.

Yeah, I know, but each one
of 'em's got a great sweet spot.

DON: We'll put 'em in a museum.

ALAN: Eh, when Charlie gets better,
I'll buy him a set of his own.

Come on, Charlie, maybe this is
the day you'll par a hole.

I'd just like to get the
ball in the hole. That's all.

Hey, Charlie.

Charlie, maybe, uh,

if you're getting
that frustrated,

there's always something else
we could do together, you know.

Actually, you know what?

I love golf.

You see, huh?

( both chuckling )

I knew it would grow on you
once you gave it a chance.

Well, what can I say?
You're a great teacher.

All right, Alan.

Show us how it's done.

ALAN:
Oh, yeah!
