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.
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
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 attach 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.
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.
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.
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.
We all use math every day...
to forecast weather...
to tell time...
to handle money...
We also use math to analyze crime...
reveal patterns...
predict behavior.
Using numbers, we can solve the biggest mysteries we know.
It's over here.
Came right over those trees.
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.
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 I 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.
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.
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.
- This is Civilian Air Traffic Control? -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?
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.
That noise you're hearing
is really the noise of the system.
Without a signal,
all we're hearing is random energy.
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.
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.
Okay,you two,you make your little jokes.
The fact remains,
we may not be alone.
What-What's that?
That's the Squish/Squash
program calculating the object's
likely flight path.
Well,it looks like the flight path of
our mysterious little object
is suddenly becoming a lot less mysterious.
This is the path of the object as calculated
by the Squish/Sguash algorithms.
And what happens here?
The signal becomes too thin to track.
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.
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...
There.
Now it's working off of all seven radar sources.
And it's building an image of the object.
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?
This is similar to the blended wing design.
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 yomight 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.
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.
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.
You believe this?
Still can't find it?
No.
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.
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.
Here it is.
Except that's not your ball.
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?
That's his truck,so he should be here.
Hey,Dad!
Dad,you in there?
Don,it's the same plane.
It's supposed to be here.
This is not possible.
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?
See,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 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.
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?
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 prey 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?
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.
'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.
Okay. Let's go. Get on the phone to LAPD.
Tell them we need Search and Rescue teams. I'm on it.
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...
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.
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.
Hey,guys!
Over here!
She found something...
Don.
It's Lane Gosnell.
He's dead.
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.
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...?
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.
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...
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?
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.
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.
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.
We'll put 'em in a museum.
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?
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.
