All language subtitles for Ancient Aliens s15e11 The Ultimate Guide to UFOs.eng

NARRATOR: Flying disks
make impossible maneuvers.

MAN:
Oh!

MICHIO KAKU:
Gravitational forces

inside these objects

would crush
any living individual.

NARRATOR:
Triangular craft

appear out of thin air.
- (alarm blares)

He actually was a hundred feet
away from that flying triangle

and could see through it
and the stars above.

NARRATOR:
Enormous cylindrical objects

fill the sky.

RICHARD DOLAN: It had
the radar return equivalent

to ten aircraft carriers,

except this was up in the air.

NARRATOR:
UFO witnesses

have reported objects
of all shapes and sizes.

Could they offer important clues

about other intelligent life
in our galaxy?

NICK POPE:
Might there be links

between the shapes of UFOs

and the different types
of entities

that are sometimes reported?

GEORGE NOORY: It's very
conceivable they're coming

from different planetary systems

throughout the universe.

NARRATOR:
There is a doorway

in the universe.

Beyond it is
the promise of truth.

It demands
we question everything

we have ever been taught.

The evidence is all around us.

The future is
right before our eyes.

We are not alone.

We have never been alone.

At dawn on April 14, 1561,

the citizens
of this Bavarian city

at the center of Europe
awake to a commotion in the sky

unlike anything they have
ever experienced before.

People went outside,

and they saw what they described
as a celestial battle.

The witnesses
observed seeing hundreds

of these strange-shaped objects.

What were these strange shapes
that they were describing?

NARRATOR:
The aerial scene,

illustrated
in this contemporary woodcut,

is described
in the accompanying text

as a very frightful spectacle.

Strange objects
seemed to launch projectiles

as onlookers below
watch in amazement.

This was actually witnessed

by thousands of people.

Had it been a meteor shower

or something like this,
then the reports

would have been,
"Okay, this happened before

because we've seen this before."

But that was new.

HENRY:
The witnesses

wouldn't have had a conception

of some kind
of a mechanical spacecraft,

but that seems to be exactly
what they were describing.

And this has to be

one of the greatest
mass sightings

of a UFO phenomena
in all of recorded history.

NARRATOR:
Incredibly,

a very similar incident
was reported

in Basel, Switzerland
five years later

and was illustrated in a woodcut

that still exists to this day.

Is it possible

that these two events
witnessed by thousands

represent the first mass
UFO sightings on record?

TSOUKALOS: The UFO
phenomenon is not modern.

It goes back
as far as we can remember,

because we have accounts
of lights and craft

not only in modern times

but also in ancient times.

NARRATOR: Ancient astronaut
theorists find it remarkable

that the depictions
of these 16th century sightings

include every shape of craft
that has been reported

by UFO witnesses
in modern times.

But it also poses
an important question.

If these are, in fact,

representations
of alien vehicles,

what could explain
all the different shapes?

BIRNES: So, it well might be
that different types

of UFOs are tasked
for different purposes.

There are scout ships.

There are ships that only orbit.

There are mother ships.

They're all tasked
for different purposes.

NOORY:
If you look at our planet today,

almost every country has
some kind of flying machine

that is different from
what we have.

I think the same thing is
the case with extraterrestrials.

Let's assume there's ten
different E. T. Races

within our Milky Way galaxy.

Each one could have a different
shape to its craft

because that's just the way
they created it.

And I think that's very
conceivable when we see

cigar-shaped UFOs,
triangular-shaped UFOs,

round UFOs.

They're coming from different
planetary systems

throughout the universe.

NARRATOR: Could the various shapes
that have been witnessed in the sky

for hundreds of years

all represent
extraterrestrial crafts,

as ancient astronaut theorists
suggest?

And if so, with a more
advanced technological

frame of reference, might modern
humans be able to gain insight

about who, or what,
is visiting Earth

by examining these shapes?

Are there conclusions
that you can make about

the different shapes of UFOs
that are reported?

Might there be links even
between the shapes of UFOs

and the different types
of entities

that are sometimes reported?

NARRATOR: In modern times,
the most commonly reported UFO shape

is the iconic "flying saucer."

The term was coined in 1947

after pilot Kenneth Arnold
spotted a number

of flying objects near
Mount Rainier in Washington,

traveling at incredible speeds.

He described them as skipping
through the air

"like a saucer," he said.

And this is really where the
term "a flying saucer" arrives

in English language, is from
Kenneth Arnold's description.

NARRATOR: With more saucer-shaped
objects reported around the globe,

the United States government
began to investigate reports

of UFO activity.

It wasn't just the United States
that was interested

in potential UFOs
in the mid-century.

Canada, France, the Soviet
Union, the United Kingdom

and Brazil all had various
programs to determine

whether or not it was a threat
for humans.

NARRATOR: Could it be
that reports of flying saucers

caught the attention of world
governments because they have

a shape unlike any
man-made aircraft?

Ufologists suggest that these
sightings triggered

a competition by world powers
to manufacture their own craft

based on this exotic design.

A design that many presumed
must have some unknown

but inherent advantage
for flight.

There's no question that,
historically,

governments have attempted to
recreate the shape

of UFO craft that have been
seen, spotted or crashed.

NARRATOR: In the 1950s,
the Pentagon funded a prototype

for a disc-shaped craft.

This once-classified project
yielded

a nearly three-ton
flying saucer:

The VZ-9 Avrocar.

TEITEL:
The Avrocar was one attempt

to develop a flying saucer.

And it was a VTOL design.
A vertical takeoff and landing.

It was designed by
a Canadian company, Avro,

for the U. S. Military.

The U. S. Air Force wanted it to
be a supersonic interceptor

and fighter,

and the U. S. Army wanted it
to be something stealthy

that could hover above
the ground in silence

and detect radar.

Avro engineers thought that this
big circular wing might be

the design that could meet
both requirements.

NARRATOR:
In 1959,

after years
of top secret development,

this flying saucer prototype
was finally put to the test.

ANNOUNCER: In preparation for
the final contractual demonstration,

a representative course
was selected

where the vehicle could
demonstrate its capability

while remaining in view
of the observers.

TEITEL: It turned out that the
cushion of air under that wing

became extremely unstable
just a few feet off the ground.

There was one model built,
and some wind tunnel tests done,

but ultimately
it was deemed completely

aerodynamically unstable.

NARRATOR:
While the Avrocar failed,

in 2019, Romanian engineer
Razvan Sabie

and aerodynamicist Iosif Taposu
unveiled their answer

to the flying saucer problem.

The "All Directional
Flying Saucer," or ADIFO,

demonstrates precision
maneuverability,

and outperforms all previously
known flying saucers

constructed by humans.

TEITEL: The ADIFO design
looks really interesting.

It looks like
a highly maneuverable

flying saucer design.

But it's small,
and it's a drone.

It would be interesting to see
how the engineering works

with a full-size design,

because engineering is
very difficult,

and usually doesn't scale up
very cleanly.

NARRATOR: This saucer
utilizes four ducted fans

like a quad copter drone,

and it is also equipped
with jets for added thrust,

and lateral nozzles that provide
side-to-side mobility

and rotation.

The saucer only currently exists
as a miniature prototype,

but its creators plan to pursue
a full-sized, manned version

capable of hypersonic speed.

If successful, will we have
finally achieved the same

technology as extraterrestrial
space travelers?

Or could recent events reveal

that they are still
light-years ahead of us?

NARRATOR: Ancient astronaut
theorists have speculated that one reason

extraterrestrials might have
designed disc-shaped craft

is so that they can instantly
change direction,

and at tremendous speeds.

CHILDRESS: We can learn a
lot from modern UFO reports.

These disc-shaped craft are able
to make sudden turns,

turning at-at high speeds
in any direction.

DOLAN: When you're thinking
in terms of aerodynamics,

shape should matter
a great deal.

But what if aerodynamics
is not really relevant?

What if these objects are able
to employ a different kind

of a science that makes
aerodynamics irrelevant?

CHILDRESS:
One of the concepts here

is that these circular
or disc-shaped craft

are using antigravity
for propulsion.

They're not rockets.

They're antigravity.

They're generating
their own gravitational field,

which would likely be

a spherical field
around the craft.

NARRATOR: Is it possible that
reports of disc-shaped objects

changing direction
at incredible speeds,

some of which have
even been captured on video,

are alien craft
with antigravity technology?

While there is no hard evidence

that antigravity aircraft
do exist,

there has been much speculation

as to how such craft
might function.

One theory
is that they could be,

in part,
driven by centrifugal force,

the force that is felt by
a rotating or spinning object.

The shape of these craft
is consistent

with these different models
of rotation

around a central axis

involving something
with high mass

and high energy.

NARRATOR: Ancient
astronaut theorists point out

that such
spinning wheel-like machines

bear an eerie resemblance
to one of the most famous

and enigmatic stories
from the Hebrew Bible,

the story of Ezekiel's wheel.

TSOUKALOS:
When you have these ideas

that are currently proposed

of these gigantic wheels
in the sky

that spin on their own axis

in order to create
artificial gravity,

I might as well be reading
Ezekiel.

It's very similar.

NARRATOR:
In the Bible's Book of Ezekiel,

the prophet describes
a fiery chariot

drawn by four living creatures.

Each creature is flanked
by a metallic object,

a wheel within a wheel,

that Ezekiel observes
as it descends,

making a tremendous
amount of noise.

In his 1968 book,
Chariots of the Gods?,

ancient astronaut theory pioneer
Erich von Daniken

proposed that what was actually
being described in Ezekiel

was a spaceship.

NASA engineer Josef Blumrich

was determined to debunk
this controversial theory.

But after painstaking research,

the author was shocked
to find himself agreeing

with Erich Von Daniken.

In 1974,

he published his own book
supporting Erich's theory,

entitled
The Spaceships of Ezekiel.

TSOUKALOS:
Blumrich reads Ezekiel,

and he has an epiphany.

Because what is he describing?

He's describing
a wheel up in space.

Blumrich says,

"By gosh, Erich is right."

And so he conceived
what Ezekiel may have described

in that ancient biblical text.

TAYLOR:
Ezekiel describes

that the outside of the wheel
doesn't spin.

The inside of the wheel spins.

So he's-he's telling us
that's the engines.

None of this
necessarily has to be magic.

This could all be technology.

HENRY: Perhaps what the wheel
actually signifies

is the secret of the gods,

the secret of their
extraterrestrial spacecraft

and how humans might be able
to reverse engineer that wheel

and ultimately make
their own craft.

NARRATOR: Is it possible that a
story from the Bible's Old Testament

describes the propulsion system

of an extraterrestrial
spacecraft?

While Ezekiel's description
of wheels within wheels

may represent
a primitive interpretation

of highly advanced technology,

one man claims
to have firsthand knowledge

that antigravity craft do exist:

Area 51 whistleblower Bob Lazar.

Investigative journalist
George Knapp was the first

to interview him in 1989

about the notorious
military base

that has long been rumored
to be hiding alien technology.

He told this incredible story,
that he'd been working

at this facility called S4,
south of Groom Lake.

That they had a hangar hidden
in the desert to make it look

like it was actually a part
of the desert terrain,

and inside those hangers
were, uh, nine flying saucers.

So Bob Lazar was tasked at
area S4, a subsite of Area 51,

to reverse engineer
the power and propulsion

of what we know
as a flying saucer.

All of the nine craft that Lazar
was able to see with his eyes

were said to have worked
on the same gravity system.

Bob Lazar said the craft
would turn belly-first

and the gravity wave amplifiers
would all point to the place

in time-space
where you want it to go.

We're talking about
a gravity-propelled craft.

We're talking about
something that...

y-you don't have any effect
of the inertia or-or momentum.

It's just instantaneously
voom-voom-voom!

One place, then the next.

BOB LAZAR:
Element 115 was

what we would call the fuel
that provided the power

for the reactor to work.

Element 115 affects gravity.

Element 115 produces
its own gravitational energy.

The resulting gravity wave
creates a distortion

in front of it, allowing
the craft to slide forward.

And that's how it proceeds.

NARRATOR: Could Bob Lazar's
extraordinary claims

about the flying saucers
he allegedly worked on at S4,

along with video evidence
of UFOs,

reveal that there are
alien aircraft in our skies

equipped
with antigravity technology?

KAKU: Antigravity is not possible
with the known laws of physics.

So when I talk to my physicist
friends about flying saucers

and stuff like that,
I get the giggle factor.

They start to giggle, their eyes
roll up into the heavens,

because, you see,
I think they make a mistake.

They assume
that the aliens are maybe

100 years more advanced than us,
in which case, yeah,

it is impossible for
a civilization 100 years from us

to reach us from the stars.

But what if, what if they are
a million years ahead of us?

New laws of physics
are gonna open up

once you have a civilization

that is a million years
more advanced than us.

And a million years is nothing
but a blink of an eye

compared to the age
of the universe.

NARRATOR: Many UFO
researchers believe the flying saucer

is designed to take advantage

of an antigravity
propulsion system,

and is the optimal shape

for maneuvering quickly
in any direction.

But what could explain
the numerous other types

of unidentified craft
that have been reported?

Perhaps further clues can be
found by examining a UFO shape

that more closely resembles
man-made aircraft:

The flying triangle.

NARRATOR: At 6:55 p. M.,
local police receive a report

of a massive V-shaped object

traveling southeast
across the night sky.

Over the next three hours,

the craft is witnessed
by thousands of people

as it journeys down through
Arizona and into Sonora, Mexico.

With most of the reports
coming from Phoenix,

as well as photographs
and video footage,

the incident becomes known
as the Phoenix Lights.

DOLAN: The entire city
of Phoenix was able to see

this half a mile-long display
of lights over the city

in a very,
very distinctive pattern.

It was a triangular-ish shaped
object seen very reliably

by quite a large number
of witnesses.

BIRNES:
Who's our best witness

to that, the best one?

Governor Fife Symington
of Arizona.

FIFE SYMINGTON: As a pilot
and a former Air Force officer,

uh, I can definitively say
that this craft did not resemble

any man-made object
that I'd ever seen.

BIRNES: He says, "Yeah, I really
did see the UFO," and he describes it.

He actually was, maybe, 100 feet
away from that flying triangle,

and could see through it
and the stars above.

DOLAN: Governor
Symington was a qualified pilot,

and in the Air Force Reserve
as well.

I think he knew
what he was seeing.

NARRATOR: The governor
of Arizona described

a strange triangular UFO
that appeared translucent,

camouflaging itself
amidst the star field above.

This incredible
mass UFO sighting

made the front page
of USA Today.

And then three years later,
it happened again.

At 4:00 a. M.,

three large triangular objects
are seen by multiple witnesses,

including police officers,

flying silently
in the night sky.

I looked up in the sky
and observed

this huge arrow-shaped,
triangular-shaped object.

NARRATOR: They are observed
for at least two hours

and over more than one town.

SCHRATT:
This is known as the famous

Southern Illinois
Flying Triangle.

We have about four different
police officers.

What they describe seeing

are three distinct
arrowhead-shaped craft.

Officer Craig Stevens...

he was directly below
one of these triangles.

And he said

that it was trying to cloak

or camouflage itself
against the night sky,

and was projecting
the star field above it

on the bottom surface,

allowing it to effectively
blend in with its background.

NARRATOR:
The ability

of triangular-shaped objects
to hide in plain sight

reminds many observers
of modern stealth technology.

Developed by the U. S. Military

in the 1970s and '80s,

stealth technology allows
triangular-shaped aircraft

to appear invisible to radar,

sonar and other
detection methods.

MICHAEL DENNIN: To make
something invisible to radar,

all you have to do is make sure

that the radar doesn't
reflect back to the receiver.

So, you send out a radio signal,
you bounce it off the plane,

you get the signal back,
and now you detect it by radar.

This all comes down to mostly
the shape of the planes,

though it's a little bit
the material, too,

but it's predominantly
the shape.

You want it shaped in a way

so that the radar either
scatters in random directions

or literally just bounces off
in a completely opposite way.

NARRATOR:
Could the masking technology

attributed
to the Illinois flying triangle

and to the craft observed during
the Phoenix Lights incident

be a highly advanced version
of this same principle?

Some kind of alien stealth?

MICHAEL SALLA: Stealth
technology has been developed

to hide some of these spacecraft

to simulate an environment
behind the craft.

So this can be done in a way
to make a craft disappear.

NARRATOR: Ancient
astronaut theorists suggest

that the triangular shape
employed

by the Phoenix
and Illinois craft,

and now by the U. S. Military,

has populated the skies
since ancient times.

As proof, they point to evidence

of triangular E. T. Surveillance
craft in the ancient world,

in the form of a symbol often
called the "all-seeing eye."

BRUCE FENTON: The triangle
with an eye in the center

is commonly used as a depiction
of God, particularly

in ancient Egypt,
but we also see this

in the Catholic faith,
Masonic circles.

We see it
on the U. S. Dollar bill,

and indeed, you know,
in some of the ancient artwork.

Now, could it be
because the craft,

which we have reported
in the skies...

they look like a triangle
with a light in the center,

rather like an eye
looking down on us?

NARRATOR: Some believe
that the eerie similarity

between triangle-shaped UFOs
and the U. S. Military's

stealth aircraft is
no mere coincidence.

Stealth technology traces
its roots back to

a single series of papers
written by a Soviet physicist.

This Soviet physicist realized

radar doesn't see
the way that the human eye sees.

And so, if you change the shape
or composition of an object,

that'll affect how it shows up
on radar.

American engineers,
when they learned about this,

went back and started
experimenting with

how to apply that
to an aircraft.

And a lot of their test work was
done at Area 51 and Groom Lake,

which, of course,
has just made it a mecca

for conspiracy theorists.

And then, later, people started
to wonder if there were actually

alien technologies there.

NARRATOR:
Area 51?

The U. S. Air Force installation
in Nevada,

long suspected to be hiding
alien technology?

Is it possible that the
conspiracy theorists are right,

and that the stealth bomber is
the result of

reverse engineering
extraterrestrial craft?

A lot of people say
this is actually something

we've developed,

back engineered from
extraterrestrial technology.

This is absolutely
quantum leap technology.

NOORY:
I think there's no question that

we have reverse engineered,

or have looked at
the shapes of these craft,

and have tried to create it
for ourselves.

Look at some of the new
stealth jets

that are coming out right now.

They're amazingly close to what
we saw 20 years ago

from UFO reports.

NARRATOR: UFOs shaped
like triangles and saucers,

reported in the skies
for centuries,

can potentially teach mankind
a lot about the alien entities

who may be piloting them.

But are these craft
the actual mother ships

that carried alien visitors
across the vast distances

of interstellar space?

Or are they simply smaller
probes designed to enter

and navigate the Earth's
unique atmosphere?

And if so, did these probes
arrive here on board

much larger vessels...

vessels with entirely
different shapes,

and with sizes that would
stagger the human imagination?

NARRATOR: Two Chilean pilots
are conducting a training mission

at 35,000 feet when they detect
something highly unexpected:

A massive cigar-shaped object.

They encountered visually
and on their airborne radar

an absolutely enormous object
in the sky.

And in fact, two separate
ground-based radars

tracked this object.

We are told that it had
the radar return

equivalent to ten
aircraft carriers.

Except this wasn't floating
on the water,

this was up in the air.

NARRATOR: One aircraft carrier
alone is a massive vessel that stretches

to about 1,000 feet in length,

and towers 30 stories
above the water.

Some can hold upwards
of 75 aircraft,

and can accommodate
over 4,000 personnel.

DOLAN: I don't know what could
be as large as ten aircraft carriers

up in the sky, but this was
quite immense.

As the pilots approached
this object...

and you have to imagine they
had to be somewhat terrified...

one of them described it as
a very elongated object

swathed in smoke.

As they got to
a certain distance,

this thing instantly accelerated
and was just gone.

NARRATOR: Based on the
descriptions of the two pilots,

many researchers believe
this to be

the largest UFO ever reported.

And, in fact, many of the larger
UFOs on record

have a similarly
cylindrical shape.

The cylindrical craft is
a typical UFO shape,

one that we see a lot of.

And, in fact, the very first
photo of a UFO is of a huge

cylindrical craft over Mount
Washington in New Hampshire,

taken in 1870, right at the very
beginning of photography.

NARRATOR:
On March 25, 1989,

an infrared image was taken
by an unmanned

Soviet Martian probe
called Phobos 2

that was beamed back to Earth.

It captured a massive 15-mile
long, cylinder-shaped UFO

approaching one of the two
small moons of Mars.

Mysteriously, moments after
the photo was taken,

the Soviet probe disappeared.

PAUL STONEHILL:
JPL was in the know.

They kept watching, I think,
every second of the mission.

They knew when
the probe disappeared

and then was destroyed.

So I think there is something
on that moonlet

that is capable of destroying
spacecraft from Earth,

and they know it.

NARRATOR Officially,
the loss of the Phobos 2 probe

was blamed on a malfunction of
the on board computer,

but no explanation was ever
provided for the enormous

cylindrical object that was
captured by its camera.

Could it be that the cylindrical
craft was in fact a mother ship

from a distant star system?

In 2017, another massive
cigar-shaped object was spotted

traveling towards Earth.

And this time, astronomers made
international headlines

when they announced that this
strange intruder had, indeed,

arrived from a distant star...

the first interstellar object
ever proven to have entered

Earth's solar system.

In October of 2017, there was
the very strange object...

very cylindrical and long
called Oumuamua,

which was, I believe,
sent to our solar system.

POPE:
We've had some space stories

which have been pretty
eye-opening, like Oumuamua,

where we've had open speculation
about how this thing might be

an interstellar spacecraft.

NARRATOR: Is it possible that
massive cigar-shaped objects

like Oumuamua, the image
captured by the Phobos 2 probe,

and the UFO witnessed by pilots
in Chile represent alien craft?

Ancient astronaut theorists
say yes,

and believe that these craft
serve a specific purpose,

one that can be found by
examining sacred Hindu texts

that date back thousands
of years.

DEEPAK SHIMKHADA:
In Hindu texts, such as

the Ramayana or the Mahabharata,

a vimana is primarily
a flying ship that God use

to travel back and forth
between spaces...

in heaven, from one planet
to another planet,

from one universe
to another universe,

and also come to Earth.

CHILDRESS: The vimana texts
describe at least five different types

of vimanas that have
different shapes.

Some vimanas are tubular,
cylindrical craft

that can carry large amounts
of people in them.

All these Vedic texts
speak of a time

when three cities were
orbiting Earth.

And from these cities,
smaller vehicles were used

in order to reach the realm
of the Earth.

Even extraterrestrials

with their advanced technology

would have to arrive
with a larger mother ship

orbiting the Earth.
And from that mother ship,

smaller vehicles will enter
the Earth's atmosphere,

going back and forth.

And this is why we have
these stories of vehicles

with which to reach the larger
palaces up in the sky.

Personally, I also think that
whatever it is seen today

with the modern UFO phenomenon,
the big craft is out there.

The so-called cigar shape
could be the larger vehicles,

which were orbiting the Earth.

NARRATOR: Could it be that
reports of cigar-shaped UFOs

are really sightings
of alien mother ships?

Are these
the interstellar barges

that transport
both extraterrestrials

and their fleet of aircraft
across vast distances of space?

Ancient astronaut theorists
say yes,

and suggest that
by more closely examining

the behavior of these
variously shaped UFOs,

we may learn something about
the beings that pilot them,

or if they are even piloted
at all.

(chatter in foreign language)

NARRATOR: An unidentified glowing
object descends from the darkness

and hovers above
the Temple Mount,

a holy site revered
in Judaism, Christianity

and Islam
for thousands of years.

(excited chatter
in foreign language)

The 2011 UFO sighting
over the Temple Mount

is absolutely fascinating.

You see this light
slowly descend.

RABBI ARIEL BAR TZADOK:
That happened in Jerusalem

on a Friday night on a Sabbath.

We have too many witnesses
from too many sources

that can prove that this
actually happened.

And this is what happened.

There was a light that appeared
over the Temple Mount.

And it was just there.
A glowing globe.

And it was picked up on film
by multiple different people

from multiple different forms.

- And suddenly...
- MAN: Oh! God!

It accelerates vertically
upwards at immense speed,

and you can hear
some of the passersby gasping

- in shock and amazement.
- MAN: Oh!

If this is genuine,
it's of extreme significance.

NARRATOR: The Jerusalem UFO
exhibited astounding acceleration

and maneuverability,
but it's hardly alone.

MAN:
Whoa!

NARRATOR:
On September 18, 2013,

in Wittenberge, Germany,

a witness records
an unidentified

triangular object
that is also capable

of accelerating
at impossible speed.

And in December 2017,
infrared footage goes public

showing a Tic Tac-shaped object
off the coast of California

that radio operators track
at 3,600 miles an hour.

The fastest man-made aircraft,
the Lockheed SR-71 Blackbird,

tops out at just over
2,000 miles an hour.

DOLAN: When you're looking
at all of the different UFO reports

over the many years,
with all of the shapes

and types of performance
that are noted...

flying saucer-shaped objects,

spherical-shaped objects,

cigar-shaped objects...

all of these have shown
incredible ability

to accelerate.
All of them.

NARRATOR:
For UFO researchers,

the most compelling accounts
are those in which the object

maneuvers in such a way
that it not only exceeds

the abilities of
any man-made aircraft,

but would actually kill
a human pilot.

DENNIN: So when you think
about things moving

and having very high
accelerations in g-forces,

we know that most things
based on organic matter

that are living
are going to be unlikely

to survive those forces.

TEITEL: There's only so many
g-forces the human body can take

before you run into
a lot of medical problems.

So with some of these
fast-moving objects...

people have seen move in ways
that would kill a pilot.

NARRATOR:
Are extraterrestrial crafts

flown by
incredibly resilient beings

capable of withstanding forces

that would otherwise
kill a human pilot?

There was this DIA report,
Defense Intelligence Agency,

about these different types
of alien creatures,

one of which is fascinating.
It's called transmorphic.

And what that means is,

these creatures aren't
corporeal the way we are.

They're energy beings,
they're light beings.

NARRATOR: Some believe these
objects that fly at bone-crushing speeds

could be piloted by beings
that are not bound

to a rigid physical form.

But others suggest
a more likely explanation

is that the craft don't have
pilots inside them at all.

KAKU:
These are hypersonic devices.

They can also zigzag,
and the amount of zigzagging

is so great that
the gravitational forces

inside these objects as they
jerk through space and time

would crush
any living individual.

In my opinion,
whatever these objects are,

they're guided
either by remote control

or by an autonomous
cybernetic system.

FENTON: Now when we look
at the cutting edge

of science today,

we realize that
space exploration

probably won't be carried out
by living people,

but instead by robot craft,

and this is already happening.

You know, our explorations
of Mars and of the solar system

involve robot craft,
not human beings.

Could it be that an advanced
extraterrestrial civilization

would have gone down
the same route

and sent living AI craft
to explore our planet?

NARRATOR: If aircraft
of all shapes and sizes

have been sent to Earth
from alien mother ships,

as ancient astronaut
theorists suggest,

could they be robotic drones
that are remotely controlled

from far above the planet?

Or is it even possible
that the craft possess

highly advanced
artificial intelligence,

and fly autonomously?

And if there are no pilots
to accommodate,

could this suggest
that these crafts are capable

of more than we ever imagined?

NARRATOR: A robotics team at
NASA's Jet Propulsion Laboratory

announces a new prototype
robotic system

that will one day be able
to explore

the most inaccessible areas
of distant worlds.

Mini-robots that can combine
and transform

to roll, fly, float,

and swim in any environment.

NASA is calling them
"Shapeshifters."

NASA is looking at
shape-shifting robots

to explore other moons
and planets.

Like Saturn's moon, Titan.

It's looking at having
a shape-shifting robot

as part of a probe
that could adapt

to the different environment
on Titan's surface.

Flying through the air,
exploring the ground,

and even going into the methane
and ethane seas.

The individual components
are kind of

self-contained mini-robots

that work together
as a collective

and create new
and interesting shapes,

depending on what you need
to go through.

It's been noted with a number
of UFOs that have been observed,

sometimes they change shape.

At one point,
they look like a triangle

and then they look like a disc.

NARRATOR: Another
technology that NASA is developing

for deep space travel
is self-replicating robots:

Artificially
intelligent machines

that are able to use
the resources found

on celestial bodies
to create more of themselves,

colonize planets,

and even evolve into
more sophisticated machines.

This has led some to speculate

that the UFOs witnessed
in our skies

are not dependent
on external control at all.

KAKU:
If you're an alien civilization

looking at the galaxy
with a hundred billion stars,

you may not want to send
Captain Kirk hopping one by one.

You'd send
self-replicating robots.

They would land on the planet,

make hundreds of carbon copies
of themselves

that would launch off
and colonize other moons.

From one robot, you would get
a hundred, then a thousand,

then a million, billion.

While we are certainly dealing
with technological craft

in certain instances,

it's also true
that we are finding evidence

for conscious entities
that are spacecraft.

NARRATOR:
From an ancient Egyptian symbol

to a 16th century
Swiss illustration,

and modern-day footage
captured by military aircraft,

is there overwhelming evidence
that UFOs

and extraterrestrial craft
not only exist,

but they have been present
on planet Earth

for thousands of years?

Flying discs
with exotic propulsion systems,

stealth aircraft that can appear
and disappear at will,

and massive mother ships
carrying space travelers

from light-years away.

As new technologies allow us
to capture more and more

unidentified flying objects,

perhaps we will soon discover

that their numbers
are far greater

than we ever imagined,

and it is not
that they are in our airspace,

but that we are in theirs.
