- [Heather] Phil, do
you see anything?
- [Phil] Nothing.

- [Heather] There's nothing?
- [Phil] What did it look like?

- [bleep].
- Oh.

- [Phil] Look at that.
- [Heather] Holy [bleep].

[Josh] On this episode of
"Expedition X"--

[Phil] All right,
there's a lake.

[Josh] Norway's ice-cold
Hessdalen Valley

is one of the world's
hottest spots for UFO activity.

Who here has seen the lights?

[Josh]
With hundreds
of reported sightings

dating back
two centuries.

Using cutting-edge tech,

Heather and Phil will
scour the skies.

[Phil] I see two lights.

[Heather] Oh,
you're [bleep] right.

- [cracking]
- [screams]

[Josh] And dive the depths
in search of the truth

behind the Hessdalen lights...

What is that?

[Josh]...asking
the earth-shattering question--

are aliens among us?

[Heather] Yes!

[Phil, on radio]

[theme music plays]

OK, guys, as you may recall,
when I was 11,

I think
I saw a UFO.

Ah, yes, that
extraordinarily nerdy letter.

Yes, I saw this diamond shape
up in the sky.

It suddenly disappeared,
and I wrote down every single

detail I could remember.
- [Heather] It's cute.

- [Josh] It's cute.
- And I'm still obsessed

with getting to
the bottom of what

may be up in the skies.
And here's the thing.

There's been some really
compelling recent evidence of,

you know, potential UFOs.
Take a look at these.

- [Josh] Look at that!
- And there's another.

- [Heather] Oh, wow!
- [Phil] Right there.

[Josh] Wow.

[Phil] None of these are planes,
none of these are satellites.

Every single one of them
is unexplained.

And they all come from the same
remote valley in Norway,

in northern Europe.
It's called Hessdalen.

Oh, I've heard of this,
the Hessdalen phenomenon.

- [Phil] Yes.
- Right?

There are, like, hundreds
of these sightings, right?

And it goes back,
like, centuries.

This is not some instance
of the Northern Lights,

this is something that's, like,
out of this world.

[camera snapshot]

[Josh]
Just south of the Arctic Circle

lies Norway's Hessdalen Valley,
an area that's infamous

for being the world's most
active location for UFOs.

The first documented sighting
comes in the winter of 1811.

Priest Jacob Krogh writes
about a huge, glaring star

with bright branches
in the night sky.

Then, in 1895,
a local newspaper runs a story

about more strange lights
above the valley.

The phenomenon intensifies
following World War II.

In 1947, multiple witnesses
including a town mayor claimed

to see an egg-shaped craft land
or crash in a nearby lake.

[people yelling]

[Josh]
The early 1980s see another
surge in sightings with as many

as 50 recorded
in a single week.

News cameras capture
the eerie lights,

drawing scientists
from around the world.

In 1998, a multinational
effort establishes

the world's first automated
anomaly detection system

to monitor Hessdalen 24/7.

Researchers capture hundreds
of videos, radar readings,

and electromagnetic anomalies.

But, today, more than
25 years later,

there is still no consensus
on what is causing

the Hessdalen lights.

UAP are airborne objects

that cannot be
immediately identified.

We are committed
to a focused effort

to determine their origins.

In the wake of the Pentagon's
admission that there are

unidentified aerial objects
among us, there's been

a renewed interest in what's
been happening over Hessdalen.

Meanwhile, reports of strange
activity only continue to rise.

Wingless craft are reported
flying over the valley

every week.

Stranger still, some say
they see otherworldly lights

alongside these UFOs,

as if the lights and the UFOs
are communicating somehow.

So far, no one has been proven
right or wrong.

Is the truth out there
in the Hessdalen valley?

I'm obviously not saying
it's definitely aliens,

but the fact that scientists
have been studying

this phenomenon for 40 years

and still haven't managed
to crack the case,

there's something
really special here.

This is a huge mystery.

I think it demands
our attention.

Totally agree with you, we have
to check this out, right?

We've done UFO stories before,

but not one with hundreds

of scientifically-investigated
sightings.

What do you think, Heather?

Well, look, for the record,
I've seen some UFOs as well.

When I was in high school,
I saw six unexplainable lights

in the sky.
So this is right up my alley.

- I'm all-in.
- [Josh] All right,

so we all agree
this needs to be checked out,

and the timing really
couldn't be better.

This close to the
Winter Solstice this far north

means very short days
and a lot of dark skies

to look for
unexplained lights.

Exactly. And I've already put
the word out for witnesses.

So by the time we land,
there should be a long line

of people ready
to share their stories.

And maybe we can go
to a Christmas market.

- [Phil] If we have time.
- [Josh] You're not gonna

have time for anything
if you don't

beam yourselves out of here.
Get going.

- Maybe a snowman?
- [Josh] Oh, my word.

- Maybe a snowman.
- Snow alien?

- Oh, yeah.
- OK.

[Josh] It's an eight-hour flight
from New York to Oslo, Norway,

then another six hours driving
north on snow-banked roads

to the Hessdalen Valley,
only a few degrees latitude

from the Arctic Circle.

[Phil] It is
a winter wonderland out here.

Look at this place.

[Heather] Well, I've got a fun,
little, Norwegian fact for you.

- [Phil] Let's hear it.
- [Heather] Did you know

that only a couple of hours away
from here is where they filmed

the ice planet Hoth
in "The Empire Strikes Back"?

- No way!
- [Heather] I know.

So if you get cold enough,
does that mean you're gonna

slice open a reindeer
and crawl inside?

No, I'm not doing that.

You could then
eat the reindeer.

Reindeer meat's great.

I am not eating
reindeer either.

We need to find some reindeer
meat when we get to town.

- I am not eating Rudolph.
- Delicious.

No.

[Heather] Oh, look!

It's the Christmas market
of my dreams!

At the mouth of Hessdalen Valley
is the town of Roros,

world famous
for its Christmas market.

[Phil] I mean, this has got
to be the most festive town

on the planet!
- It's adorable!

This is amazing!

See the Christmas tree
back there?

[Heather gasps]

[Heather] I love it.
I love it.

Did you know this is
one of the places

that inspired "Frozen"?

So, this is like
a mini Arendelle.

Yes.

And I feel frozen right now,
so it all makes sense.

[Heather] Oh, my gosh!

Ooh, look, candy canes
and Christmas garland.

- Ooh, and Santa Claus hats.
- Oh, my God, those.

That's exactly what
I was looking for.

- Two reindeer sausages, please.
- Two?

Uh-uh.

One reindeer sausage
and one cookie.

- [both] Ooh.
- [Phil] Thank you.

- [Heather] Oh,
it's like a hot dog.
- [Phil] Yeah.

[Phil] What did you think?
It's in the shape of
a little reindeer?

- [Heather] Well, I don't know.
- Ketchup's frozen.

I'll eat it plain.

[Phil] Do I have reindeer
in my teeth?

- [Heather] No.
- [Phil] OK.

[Phil] After our tasty treat,
we drive another hour north,

deeper into
the Hessdalen Valley.

We head to a local church
where we've arranged a town hall

in order to hear from as many
local witnesses as possible.

Thank you all for joining us.

Only 150 people
live in the region,

but because the phenomena
is such a chilling mystery,

our town hall appears to be
the hottest ticket around.

To me, the Hessdalen phenomena
is the most underappreciated

mystery in the entire world.

The fact that they are real,
they are here, they're being

studied by scientists, they're
being seen countless times

for hundreds of years,
and we still don't know

what it is, what they are,
who they are.

By a show of hands,
who here has seen the lights?

All right, that's awesome!
There's a lot of y'all.

Anybody care to start out
and share your story?

Two years ago, when I was out
ice-fishing at night,

I was there on the ice,
waiting for the fish to bite.

And I can see an orange light
in the sky,

quite strong.

I forgot about the fish.
My heart was moving so fast.

[heartbeat thumping]

And then...

the light disappears.

I've never seen
anything like that.

It's amazing.
Thank you.

[speaking foreign language]

[translator speaking]
First time I saw the objects
was early '80s.

[speaking foreign language]

[translator speaking] At first,
I thought it was an airplane,

and it was hovering
above the river.

It had the shape of a banana,
but it was a bit bigger

in the middle.

It followed the rivers,
and then it disappeared

into the woods.

So we call them
the Hessdalen Lights,

but what you're talking
about seeing that sounds

more like a physical object
flying around here.

Many people have
seen object, many.

The light stops,
and change direction,

and disappears.
It was very big.

- 20 meters wide, maybe.
- That's huge!

When it was two meters
from the ground, it stopped.

The impression I got
was not welcome.

One of the cases we have
where there's seen beings

rushing over the field.

Wait, so people are reporting
seeing beings?

[witness] Beings.

Listening to all the stories,
if you add together,

it doesn't sound
like natural phenomenon.

It sounds too intelligent.

There is something that
interacts with people.

There is some kind of
phenomenon we don't understand.

What did it do?

[scientist speaking]

You think
it mimicked your light.

[Phil] You've been
studying them for how long?

40 years.

Where do we start
if we want to try to see this?

[Phil] The White Box is
a small research station

perched atop Skarvan Mountain,

overlooking
the Hessdalen Valley.

It was established in 2018
by local scientists

to study the light phenomena.

And Heather and I have been
granted exclusive access to it

for our investigation.

I think right around here
is as close

as the road's gonna
take us.

But getting there will be
a serious workout.

All right.

It looks like we've got
a four-mile hike

and 2,000-foot elevation gain.

Yeah and we gotta get there
before the sun sets.

- Yeah, so we should get moving.
- [Heather] All right.

[Phil] The terrain is too rugged
and rocky for snowmobiles,

so the only option, snowshoes.

We've got to get a move on.

There's less than two hours
of daylight left

before a 19-hour night falls
when temperatures can get as low

as negative 22 degrees
Fahrenheit.

- [Phil] Ready?
- [Heather] Yeah.

- [steps crunching]
- [music plays]

Gotta get up there.
A long ways to go.

[bleep].

[Phil] You got it.
Tall steps.

This is some harsh,
harsh conditions.

- [Heather] Whew, OK.
- [groans]

- [Phil] Having fun?
- [Heather grunts]

[Phil] You got it.

[wind whistling]

[Phil] There it is, look!
The White Box!

[Heather] We made it!
Finally!

[Phil] Oh my god.

[Heather] Phil, I see something.
Holy [bleep].

[Phil] We're almost
right on top of it.

- [bleep].
- What is that?

[Phil, on radio]

[whoosh]

- [Heather] We made it!
- [Phil] Woo!

[Heather] Oh, home sweet home.

[Phil] Oh my gosh!

Wow!
This is wild!

[door squeaks]

- Woo.
- [Heather] Woo.

- Oh, my gosh.
- [Heather] Look at this place.

[Phil] That...

was a mountain.
- Yeah, you're not joking.

Look, we got bunks, table,
roof over our heads.

OK, life of
a research scientist up here.

- Control room?
- Let's check it out.

[Phil] Wow.
OK.

- [Heather] This is it.
- [Phil] My contact said,
all the computers are running.

[Phil] We just gotta
open them up.

[Heather] OK.

[Phil] Look at that.
Incredible!

So, over here, looks like
a weather station.

It's got wind,
temperature, solar radiation.

Amazing!

Geiger counter,
measuring microsieverts.

We got different
live feed cameras.

[Heather] Definitely
an airline tracker.

We know when flights
are going over.

[Phil] Yes.
Star tracker right there.

This is the EMF reader.
What else do we got?

360 camera
and magnetometer.

- A lot of toys in this toy box
- [Phil] Oh, yeah.

But we got a couple more toys
we can add to the mix.

Should we set up the DAP-cam?

[Heather] Yeah, let's go
set up our stuff.

[Phil] The DAP-cam stands for
Data Acquisition Project.

It's something we deploy
any time we're on

a sky-watching
expedition like this.

We had great success
with it in Japan

and in Utah's Uinta Basin.

OK.
DAP-cam should be live.

This thing has a 360 view
of this entire area.

It will lock on and track
anything flying in the sky.

And because it's connected
to the internet, it can identify

those things and categorize
them as airplane,

as satellite, or--
- UFOs.

Other.
All right.

[Heather] As we begin our
sub-arctic skywatch,

I set up in the cozy
White Box control room,

where I'll monitor
the DAP-cam

and the other instruments.

Meanwhile, Phil got
the short straw

and will be braving
the elements outside,

keeping an eye on the skies
over the valley.

You set it on a time-lapse

because this is
a light phenomena,

and any light should show up
pretty well on this.

I've got nothing on the DAP-cam.

I do have the town in sight,

so I can see if something is
coming up from the ground,

which some of our witnesses
have spoken about.

I've got a pretty good range,
and I'm tracking the sky,

so if something shows up,
we'll be able to see it.

[Phil] Oh, my God!

It is freezing out here!
The wind is relentless

So, this camera has
a super-high ISO sensor,

meaning it can capture
even the dimmest of lights.

And I paired that
with my wildlife lens.

This is a 500-millimeter lens.

It's basically
like a telescope.

As far as I know, no one has
had a camera combination

as powerful up here,
meaning we potentially could

document the Hessdalen Lights
like never before.

[ominous tone plays]

[Phil] Wow.

What is that?

I got a light.

[Phil talking]

I can't tell if that is
a farm below that I'm seeing

in the valley,

but that's the way we came up,

and I didn't see any farms
down there.

It's really hard to tell
if the light is moving

or if it's stationary, so...

I'm a little skeptical,

but I have no idea
what that is.

And it's gone.
Disappeared.

What I do know,
I got some good video of it

so we can review the footage
and find out.

Bizarre.
Heather, you copy?

Yeah, what's going on?

- Saw my first light.
- No way, where?

It was over the lake.

As far as I can tell,
it looks stationary.

So there's still a chance
it could have been a farm

or a campground or something
out there, but got it on video

and then disappeared.
- No.

Yes.

Anything showing up
on the DAP-cam?

I've got nothing so far,
and nothing on

the Geiger counter
or the EMF detector.

Well, the night is young,
so let's keep at it.

Copy that.

[anticipatory music plays]

[camera shutter snaps]

[computer beeps]

[Heather] Holy [bleep].

- Phil, I see something.
- [Phil] What'd you see?

Go to city side.

Look at this!
Holy [bleep].

Phil, tell me you're seeing
something out there right now.

[Phil] Where, where, where,
where, where, where, where?

I'm over here, Heather.
I don't see anything.

[Heather] EMF is spiking.
We're at 104 right now.

It just disappeared.

I'm getting out there.

- [Heather] Phil,
you see anything?
- [Phil] Nothing.

- [Heather] There's nothing?
- [Phil] Just city lights.

Saw some headlights from cars
that would flash at times?

[Heather] No, that's not
what I saw.

[Phil] What did it look like?

[Heather] It looked
like this light.

It was up in the sky
on the horizon,

and then it disappeared.
- [Phil] Wow.

- [bleep].
- Oh!

Look at that!

- [Heather] Holy [bleep].
- [Phil] Oh my God!

[whoosh]

- [Phil] There it is!
- [Heather] I told you
I saw something!

[Phil] Oh my god!

No way!
Recording, recording.

Just got to get it in focus.

- [Phil] Yo, where'd it go?
- [Heather] It's gone.

[Phil] What?

- [Heather] Oh, there it is.
- [Phil] It's back.

[Heather] [bleep].

- Wait, I see two.
- No.

- [Phil] I see two lights.
- [Heather] Oh, you're
[bleep] right.

- [Phil] You see it?
- [Heather] Yes!

[Phil] What the hell?
I mean, yeah, I see flashing.

It looks like a plane,
but it moved

to the right and left.
- [Heather] It did.

[Phil] OK, I'm getting this.

What the [bleep]?
Where'd it go?

Where'd it go?
Where'd it go?

[Heather] It's gone!

There's two of them.
There's two of them.

We got to check that
on flight tracker.

Wow!
Totally different than
what we saw before.

You saw it move to the right,
too, right?

I did.
It was moving left,

and then it
looked like it jumped right.

I'm not getting
any sleep tonight.

[Phil] No. Hessdalen Valley's
putting on a show for us.

Yeah.

[Phil] All right.

Eager to finally get a break
from the bitter cold,

I head into the White Box
control room

to see if our DAP camera

managed to capture any of
the strange lights we witnessed

with our own eyes.
- [Heather] Did we get it?

Yes.
Take a look at this.

[Heather] Wow!

[Phil] You really get a sense
on the DAP-cam how the light is

getting brighter.
- [Heather] Yeah.

[Phil] And dimmer,
moving left, right.

[Heather] And it's tracking it
the whole time.

[Phil] Yeah.

[Heather] There's no flights
on the flight tracker?

[Phil] Nothing!

And those are stars that are
starting to show up.

OK.

That is so much brighter
than a star.

- Yeah.
- [Heather] And the DAP-cam
didn't identify it.

[Phil] Isn't that wild?

DAP-cam is still running,
and we have one

very good recording.

- Of a UFO.
- Of the Hessdalen phenomena.

It's getting late, and we need
to constantly be watching

this thing, I think we should
take some shifts.

OK.

Does that mean
you're taking first shift?

[Heather] Sure.
It looks like you need a nap.

[Phil] Yeah, I'm gonna
get some shut-eye.

I call bottom bunk.

[Heather] We take turns watching
the valley skies from

the control room throughout
the rest of the night.

But we don't capture
anything else as compelling

as that light.

[dramatic music plays]

[Phil] After a long night
becomes a very short day,

Heather and I split up to find
out more about the possible

sources behind the lights
we saw at the White Box.

Thank you so much for granting
us access to the observatory.

- That place is wild.
- Yes.

- Not easy to get to.
- No, it is not.

[Phil] I go to meet
Anna-Lena Kjoniksen,

an engineering professor
at Norway's Ostfold University.

She and a team of scientists
have been trying to solve

the Hessdalen light phenomena
for more than 25 years.

We've talked
to many witnesses here.

- Yeah.
- People claiming to see
different types of lights

in the sky, people claiming to
see crafts flying around here.

We saw some interesting things
ourselves at the observatory.

We saw some brief flashes
of light in the valley.
- [Anna-Lena] Yeah.

Could that have been
the Hessdalen phenomena?

This first clip here,

believe me when I tell you,
it was weird.

[ominous music plays]

[Anna-Lena talking]

- [Phil] Really?
- [Anna-Lena talking]

What are they?

What is under the ground
in Hessdalen Valley

that's unusual?

[Anna-Lena talking]

- [Phil] OK.
- [Anna-Lena talking]

So there are so many metals
in the ground that

they've basically
formed a circuit...

- Yes.
- ...under the ground

that can carry electricity
from one side

of the valley to another?

So how does what's happening
underground

connect to
what's happening in the sky?

It seems like
you've got a tough job.

All right, see what
we can find.

[Heather]
While Phil is off gathering
intel at the local university,

I head to the other end
of the valley to meet with

a leader of another group
researching

the Hessdalen phenomenon.

[Rune talking]

[Heather] Good to see you.

- [Rune talking]
- [laughing]

[Heather] Rune Rostad is one of
the local with local witnesses

we met at the town hall.

He spent a fortune building
this one-of-a-kind mobile

research station devoted
to solving the mystery

of the Hessdalen lights.

Tell me about this place.

[Rune talking]

Yeah, and it's hard to get to,
and it's cold.

[Rune talking]

[Heather] I imagine you can
go anywhere in this thing.

[Rune talking]

Wait, so you saw something,
too, last night?

We saw lights last night, too.
What did yours look like?

Because I know at different
points in the valley,

they look different
to different people.

[Rune talking]

But theoretically, when
you see these lights

and you have this unit,
what are you gonna do?

You think it's
a physical object, then?

[Heather] Now, in all your years
researching, what has been

the most exciting
piece of evidence?

[Rune talking]

[Heather] What am I looking at?

So I'm looking at a UFO
right now, under the water.

The mayor saw this UFO land
on this lake?

[Rune talking]

You think that maybe
it's still there today?

[Rune talking]

Well, maybe we can
help you with that.

- [Rune talking]
- Yeah.

You share those coordinates,
and we'll figure out

what's going on.

I think I'm gonna
send Phil on that one.

[laughing]

Rune's story may sound
like science fiction,

but after doing further
research,

it actually checks out,
except for the year.

In the summer of 1947, the same
year the Roswell Incident

made headlines in the US,
multiple sources

described an unidentified
object plunging

into Lake Djupsjoen.

The event sparked a UFO search.

Nothing conclusive
was discovered.

Rune's sonar anomaly

is the best evidence
captured to date.

Could it confirm the bizarre
reports from 80 years ago?

Phil and I meet back up
to follow Rune's coordinates

to the frozen lake
and discover for ourselves

what's really down there.

[engine humming]

- [Phil] All right,
there's the lake.
- [Heather] Oh, yeah.

- [Heather] All right.
- [Phil] OK.

[Phil] Let me check GPS,
see where we're going.

My lord!

So, according
to Rune's coordinates,

the crash site should be
about a mile from shore,

and see the island?

Let's aim about 300 yards
to the right of there.

You think this thing is
really gonna hold us, though?

- I mean, I say let's find out.
- Oh, Jesus.

[engine rumbles]

[Phil] Lake Djupsjoen is
about three miles long

and has an average depth
of 420 feet.

[Phil] What could
be under the ice?

That's the question.

[Phil] By mid-December,
it's already been frozen

for over a month,

and the locals say it should
be able to hold us.

[Heather] So far, so good.

[Phil] GPS shows about
100 meters out.

Should be about 20 feet
in front of us.

Stop, stop, stop!

We're almost
right on top of it.

- [cracking]
- [screaming]

[whoosh]

[Heather] Oh my god.

I am incredibly nervous
right now.

See any cracks in the ice?

- No.
- OK.

- That was loud.
- Yeah.

I mean, listen,
a lake this big

should have thousands
of tons of ice, very thick.

It's gonna make little
adjustments here and there.

It's growing pains.
It's winter.

- [Heather] So that's normal?
- Within the realm of normal.

[Phil] But do you see
what's right in front of us?

Are we here?

[Phil] GPS says we're
basically right here.

X marks the spot.
Time to bring out the big guns.

[Heather] All right.

[Phil] OK, first things first.

We'll drill down,
see how thick this is.

[Heather] Oh, boy

This goes against everything
inside of me right now.

[scraping]

Why are you getting so far away?

I'm just playing it safe.

[Phil] Whoa!

I'm in!
Look at that!

- It's about six inches thick.
- I'm sorry, what?

Six, seven inches.

- Isn't that not that thick?
- That is.

We could probably drive a car
on this ice.

- [Heather] So what's next?
- [Phil] Let's get the chainsaw.

- [dramatic music plays]
- [motor cranks]

[Phil]
Our plan is to carefully cut
a hole in this lake ice

big enough for
our state-of-the-art ROV

to squeeze through.

If it sees anything
on its sonar,

particularly any possible traces
of the reported UFO crash

from 80 years ago,

then I'll dive down into
the lake myself

to try and confirm

and maybe even recover
a piece of it.

To be able to dive under
the ice using this hole too,

the triangular shape allows
for the easiest entry and exit

because of its closer angles.

All right, look at that!

We officially got
our hole in the ice.

- Let's push them under.
- All right.

- Ready to start with this one?
- Yep.

OK, on three.

One, two.

[grunting]

[Phil] Wow!

[Heather] You got that one?

- [Phil] Giant ice cube.
- [Heather] All right.

[Phil] Get this thing under.

[Heather] OK.

- You know what they call that?
- [Heather] What?

- An ice-osceles triangle.
[isosceles].
- Oh, god.

[Phil] But to be honest,
it's a giant hole in the ice.

- Let's not fall in.
- [Heather] Yeah, of course.

Let's get eyeballs
on this thing.

[Phil] Let's do it.
Grab the ROV.

The alleged UFO at the bottom
of this lake is believed to be

buried under a thick layer
of mud.

- [Heather] There she is.
- [Phil] Oh, yes.

[Phil] Luckily, our ROV sonar
can penetrate those layers.

So, similar to what we use
in Loch Ness,

this is an underwater ROV
with the normal lights and sonar

and video, but has this
technology that's not even

on the market yet
from Norbit Subsea.

It is a sub-bottom scanner.

This thing supposedly crashed
here 80 years ago,

so there's gonna be some muck
on top of it.

Using this technology,
I think we'll be able to see

what's down there.
- [Heather] OK.

[Phil] All right,
help me throw it in.

All right, ready?
One, two, three.

[splash]

Now let's get this thing...

moving.

[Heather] Phil, is that
a Nintendo controller?

Oh, yeah.
OK, going down.

So the way this scan works,
if we look on this sub-bottom

profiler right here,
that line right there,

that is the bottom of the lake,
first layer.

Anything below that, that's
where it gets interesting.

OK, so we'll keep
eyes on that.

[Phil] So, going straight down.

OK, 16 meters.
Should be close to the bottom.

Right now,
it is just pitch black.

- [Heather] Whoa!
- [Phil] Holy [bleep].

[Phil, whispering]
It's the bottom.

Look!
Something's showing up!

[Phil, normally] That top layer,
that's the bottom.

Right there, we got
something solid.

- It's huge!
- [Phil] There's
something down there!

[bleep] is there
something there?

Holy [bleep].
What is that?

[Phil] Look at that.
Look at that shape.

It's almost triangular.

It looks like
debris or something.

[Heather] Yes.

- [Phil] Oh my god.
- [Heather] I think we found it.

The Hessdalen phenomena

might be Scandinavia's most
active UFO mystery,

but it's far from the first.

On April 8, 1665, six fishermen
in the Baltic Sea,

south of Sweden,
reported an astonishing sight.

Flying vessels locked in
an epic aerial battle overhead.

And things would
only get stranger.

A massive, flat, round shape

then began hovering ominously
directly above them.

The men sailed home in terror,

reportedly still shaking
the next day.

Newspapers were
in their infancy,

but they jumped
on the story,

publicizing it
throughout the region.

So what's the truth?

Is this story an example

of 350-year-old
media sensationalism?

Or is it the chilling first
evidence of the UFOs

that many say still visit
Scandinavia today?

[whoosh]

[Phil] Look at that.
You can see it.

There's something
down there.

Holy [bleep], we found it!

This confirms it.
We're in the right spot.

Yeah, this is exactly where
Rune said it would be.

[Phil] Shoot, that's silting up
the entire bottom.

[indistinct] where to go.

We're losing visibility.

We're losing it.

[bleep].

Whoa, is it dead?
It's just dropping.

- Lost manual control.
- Lost control.

[Phil] Oh my god.

OK, back on.

Now, before
we really lose this thing,

I think we should
pull it out.

We've got the data.

It's gonna take a while
to analyze to give us a sense

of the scale and actual shape
of this thing.

But while it analyzes,

I think I should dive and see
if I can figure out what

it's made of, maybe even
collect a sample.

- You sure about that?
- Oh, yeah.

[Phil] This will be the most
dangerous dive of my life.

I'll be diving using a special
dry suit to shield me

from the near-freezing
water temperatures,

at least temporarily.

I'll only have about
20 to 30 minutes down there

before I'm risking hypothermia.

If anything goes wrong, I will
have to abort immediately.

And because I'm diving
under solid ice,

I have to be constantly aware
of my surroundings.

I can't just surface anywhere
like a normal dive.

There's a real risk I could
end up trapped.

under the ice.
The stakes could not be higher.

- [Heather] You're insane.
- [Phil] Do you want to join me?

[Heather] No.

[Phil] Once I get under and get
adjusted to the temperature,

Heather will pass down
the metal detector.

It will hopefully confirm that
the object down there

is indeed metal,
and will also help me find it

in the near total darkness.

Phil, you ready?

[Phil talking]

[Heather] Copy that.

- [splash]
- [bubbling]

[Phil talking]

[ominous music plays]

Don't be a hero, Phil,
if you're too cold, surface.

[Phil talking]

How's visibility down there?

[Phil talking]

Are you OK?

[Phil talking]

- You got a hit?
- [Phil talking]

Great job Phil,
I think we found it.

I think you found a UFO.

[Josh] Next time
on "Expedition X"--

The team's investigation
of Hessdalen comes crashing down

to earth with reports it's not
just lights people are seeing

out in the frozen forest.

Suddenly, I saw two creatures
running on two legs.

[Josh] It's alien beings.

And you are certain they were
not human,

they were not wildlife?
- Very, very certain for that.

[Josh] Their search for answers
leads them underground.

Look at that.

[Phil] Holy [bleep].

[Josh] Then, back to the skies.

Can Heather and Phil find a way
to have a close encounter

of the third kind?
- [Phil] Holy [bleep].

[Phil] Look, look, look.

[dramatic chord strike]
