Narrator:
THEY'RE WATCHING YOU.

MORE THAN 4,000 SATELLITES
CIRCLE THE EARTH.

EVERY DAY,
THEY UNCOVER NEW,

MYSTERIOUS PHENOMENA
THAT DEFY EXPLANATION.

INSIDE THE TOP SECRET
TERROR DOMES.

THAT'S GOTTA BE
ONE OF THE MOST

UNUSUAL BUILDINGS
I'VE EVER SEEN.

Narrator:
ROMANS IN THE AMERICAS.

WHAT IS A ROMAN RUIN DOING
IN THE MIDDLE OF THE ANDES?

IT REALLY BOGGLES THE MIND.

AND DAWN OF THE ICE MUTANTS.

Carter: IT SOUNDS LIKE
SCIENCE FICTION,

BUT IT REALLY ISN'T.

Narrator:
BAFFLING PHENOMENA.

MYSTERIES FROM SPACE.

WHAT ON EARTH ARE THEY?

**

FEBRUARY 17, 2020.

CARLO MUNOZ IS
ON MAINLAND BRITAIN,

MAKING HIS WAY TO
THE COUNTY OF SUFFOLK

ON THE FAR EAST OF THE ISLAND.

A SATELLITE PASSING
ABOVE ITS COAST

HAS CAPTURED
SOMETHING BIZARRE.

Moran:
THIS IS REALLY PERPLEXING.

IT'S LIKE A HUGE FAN
EMBEDDED IN THE EARTH

LIKE SOME KIND OF GINORMOUS
ANCIENT BASEBALL DIAMOND.

Narrator: MUNOZ IS
A MILITARY JOURNALIST

AND RECOGNIZES
THE MASSIVE FEATURE.

THIS PARTICULAR STRUCTURE IS
PART OF COBRA MIST,

WHICH WAS BASICALLY A JOINT
AMERICAN-BRITISH INTELLIGENCE

PROGRAM DURING THE COLD WAR

SPECIFICALLY DESIGNED
TO SPY ON THE SOVIETS.

Narrator: CONSTRUCTION OF
THE HIGHLY CLANDESTINE

EARLY-WARNING RADAR STATION
BEGINS IN 1968,

BUT IT'S PLAGUED
BY TECHNICAL ISSUES,

AND THE GOVERNMENT SHUTS IT DOWN
BEFORE IT BECOMES OPERATIONAL.

Morgan: IT PICKED UP
A GREAT DEAL OF BACKSCATTER,

AND THAT BACKSCATTER MADE IT
THEREFORE ALMOST IMPOSSIBLE

TO TELL THE DIFFERENCE BETWEEN
A FLOCK OF BIRDS IN FLIGHT

OR A FLIGHT OF SOVIET
BACKFIRE BOMBERS.

Narrator: YET MUNOZ
HAS FOUND EVIDENCE THAT

THE STORY OF THIS STRANGE
FACILITY DOESN'T END THERE.

Munoz: LOOKING AT
THE SATELLITE IMAGE,

THERE'S SOMETHING
ELSE THAT REALLY BUGS ME.

ABOUT A MILE AWAY
FROM THE COBRA MIST LOCATION,

THERE'S ABOUT 10
BUNKER-LIKE STRUCTURES,

AND I CAN'T REALLY DETERMINE
EXACTLY WHAT THEY'RE THERE FOR

OR WHY THEY WERE BUILT.

Narrator:
THE BUNKERS DON'T LOOK LIKE

ANY KNOWN RADAR TECHNOLOGY,

NOR DOES MUNOZ BELIEVE THAT
THEY'RE GUN EMPLACEMENTS.

Munoz: NOW, IF THERE'S NO
DEFENSIVE PURPOSE FOR THEM,

WHAT ARE THEY DOING THERE?

AND WHY ARE THEY
SO HIGHLY FORTIFIED?

Narrator: FOLLOWING
THE IMAGE COORDINATES,

MUNOZ ARRIVES AT AN ANCIENT
VILLAGE CALLED ORFORD.

**

THE MYSTERY STRUCTURES
LIE HIDDEN ON

A STRIP OF LAND ONLY
ACCESSIBLE BY BOAT.

**

-Munoz: HEY.
-NICE TO MEET YOU.

Munoz: NICE TO MEET YOU.

**

Narrator:
THIS RIVER IS CALLED THE ORE,

AND 1,000 YEARS AGO,
IT CARRIED VIKING RAIDERS

SEEKING PLUNDER INLAND.

TODAY, IT FORMS
A PERFECT DEFENSIVE BARRIER

AROUND THE SITE
REVEALED FROM SPACE.

[ METAL SQUEAKING ]

[ SEAGULLS CALLING ]

IF YOU WERE TRYING TO
DISGUISE OR HIDE SOME SORT

OF PROJECT, POSSIBLY
CLASSIFIED OR TOP SECRET,

THIS REALLY WOULD BE
THE PLACE TO DO IT.

Narrator:
MUNOZ FINDS HIMSELF ON A BLEAK

10-MILE STRETCH OF SHINGLE
AND STONE,

BUFFERED BY THE FREEZING
WATERS OF THE NORTH SEA.

**

**

THIS IS REALLY,
REALLY BIZARRE.

I MEAN, THIS BUILDING,

IT LOOKS LIKE THERE'S BEEN
A LOT OF GRAVEL PILED AROUND

THE SIDES, WHICH GIVE IT
AN ADDED LAYER OF PROTECTION.

-[ METAL SQUEAKING ]
-[ MUNOZ GRUNTS ]

AH!

THIS -- THIS HALLWAY HERE,
IT'S JUST -- IT'S MASSIVE.

THIS WAS DEFINITELY
SOMETHING DESIGNED

TO BRING IN HEAVY MACHINERY,
HEAVY TRUCKS.

**

LOOKS LIKE THIS ROOF IS
GONNA GO ANY SECOND.

Narrator:
WHATEVER TOOK PLACE HERE,

IT APPEARS TO HAVE LEFT A TRAIL
OF DESTRUCTION IN ITS WAKE.

GOT A SIGN HERE.

**

"TRIAL IMMINENT.
NO ENTRY WITHOUT PERMISSION.

TRIAL IN PROGRESS."

SO IF YOU HAD TO WARN PEOPLE

TO KEEP AWAY FROM
THESE FACILITIES THIS FAR BACK,

THEY HAD TO HAVE BEEN TESTING
SOMETHING INCREDIBLY DANGEROUS.

**

Narrator: THE NEXT STRUCTURE
OFFERS A SINISTER CLUE

TO THE NATURE OF
THESE TRIALS.

WHAT'S REALLY INTERESTING IS,

LOOKING INSIDE,

YOU SEE THIS KIND OF STRANGE
SORT OF PANELING.

THAT TELLS ME THAT THIS IS

PROBABLY SOME SORT OF
RESEARCH FACILITY.

I KNOW THE BRITISH DID A LOT
OF RESEARCH INTO NERVE AGENTS.

YOU KNOW, THEY TOOK TECHNOLOGY
THAT THEY -- FROM THE GERMANS

IN WORLD WAR II AND STARTED
REFINING IT ON THEIR OWN.

I ALSO KNOW
THAT THE BRITISH DID

DO SOME WORK WEAPONIZING
THOSE NERVE AGENTS.

Narrator: THE EXPERIMENTS
ON LETHAL COMPOUNDS

SUCH AS SARIN LEAD TO
THE DEVELOPMENT OF

THE INFAMOUS VX NERVE AGENT
DURING THE 1950s.

AS IF THE COLD WAR
DIDN'T PROVIDE

ENOUGH OF A CATALOG OF
HORRORS FOR US,

ONE THING THAT WE NOW KNOW IS
THAT THESE ARE, IN MANY CASES,

TESTED ON SUBJECTS THAT
WEREN'T AWARE THAT THEY WERE

BEING EXPOSED TO THESE AGENTS.

Narrator: THE TESTS INCLUDE
PUMPING BACTERIAL SPORES

INTO THE LONDON SUBWAY SYSTEM.

[ INDISTINCT VOICE
OVER INTERCOM ]

Narrator: AND THE AERIAL RELEASE
OF CLOUDS OF PLAGUE MICROBES.

Moran: DURING ONE INCIDENT,
THE BRITISH DROPPED

THIS CHEMICAL SUBSTANCE OF
UNKNOWN TOXIC POTENTIAL

ON NORWICH,
WHICH IS ONLY 50 MILES

FROM THE EXACT SITE OF
OUR SATELLITE IMAGE.

Munoz: THIS AREA,
BECAUSE IT'S SO ISOLATED,

IS THE RIGHT PLACE TO DO
THESE KINDS OF TESTS.

Narrator: MUNOZ HOPES THE FINAL
STRUCTURES WILL SHED

LIGHT ON THE NATURE OF
THESE EXPERIMENTS.

THAT'S GOTTA BE ONE OF
THE MOST UNUSUAL BUILDINGS

I HAVE EVER SEEN.

[ BIRDS CALLING ]

**

YOU KNOW,
THE WAY IT'S DESIGNED.

IT'S LIKE SOMETHING YOU'D SEE
IN ANCIENT GREECE,

NOT THE COAST OF ENGLAND.

Narrator: THE WEIRD EDIFICE
IS UNLIKE ANYTHING

THE MILITARY JOURNALIST HAS
ENCOUNTERED BEFORE.

IF THIS STRUCTURE WAS USED FOR
SOME SORT OF WEAPONS TESTING,

WHAT WERE THEY TESTING, AND
WHERE DID THOSE WEAPONS END UP?

**

Narrator: COMING UP...

THE STRANGE COMPOUND'S
DEADLY SECRET.

Munoz: IT HAS SORT OF
A GRAVEYARD FEEL TO IT.

Narrator: AND WEIRD SCIENCE
AT THE END OF THE EARTH.

IT MAKES ME WONDER WHAT'S
REALLY HAPPENING HERE.

**

**

Narrator:
DRAWN BY A GROUP OF LARGE,

ISOLATED BUILDINGS
REVEALED FROM SPACE,

CARLO MUNOZ IS ON THE SUFFOLK
COAST IN ENGLAND.

HE'S DISCOVERED A FORSAKEN
MILITARY RESEARCH FACILITY

POSSIBLY USED TO DEVELOP
AND TEST NERVE AGENTS.

THERE'S NO ONE
AROUND HERE FOR -- FOR MILES.

SO, IF IT GOES BAD,
NO ONE WOULD REALLY KNOW.

Narrator: TWO STRUCTURES ON
THE CLANDESTINE SITE

REMAIN UNEXPLORED.

THEY APPEAR TO CONCEAL
LARGE PITS IN THEIR CENTERS.

Munoz: THE ROOF ON
THIS STRUCTURE IS JUST MASSIVE.

I MEAN, THAT'S GOT TO BE
A GOOD 4 OR 5 FEET THICK

OF JUST PURE CONCRETE,
AND IT'S SUPPORTED BY

THESE SERIES OF PILLARS.

Narrator:
TO THE MILITARY JOURNALIST,

THE DESIGN SUGGESTS HIS HUNCH

ABOUT CHEMICAL WEAPONS
TESTING WAS WRONG.

YOU DON'T NEED A WALL
THIS THICK TO TEST

HOW A CHEMICAL OR NERVE AGENT
AFFECTS A SOLDIER,

SO THAT CAN'T BE
WHAT'S GOING ON HERE.

THIS STRUCTURE WAS USED
FOR SOME SORT OF HEAVY

WEAPONS TESTING.

IF THAT TEST WENT WRONG,

WHAT WOULD LIKELY HAPPEN IS
THE EXPLOSION WOULD

BLOW THESE COLUMNS OUT

AND BASICALLY DROP
THIS MASSIVE CONCRETE ROOF

ON TOP OF THE BLAST PIT.

Narrator:
AND MUNOZ HAS SUSPICIONS

ABOUT WHAT KIND OF
WEAPONS TEST WOULD NEED

A SARCOPHAGUS THIS BIG
AND THIS FORTIFIED.

THE ONLY WEAPON I KNOW
WHERE, IF THE TEST GOES WRONG,

YOU WANT TO ENCASE EVERYTHING
IN CONCRETE,

IS A NUCLEAR WEAPON.

Narrator:
IF THIS IS A NUCLEAR FACILITY,

ITS APPARENT AGE
IS INTRIGUING.

Munoz: THE CONSTRUCTION

LOOKS LIKE SOMETHING
YOU'D SEE IN PROBABLY

THE EARLY FIFTIES.

AND IF THAT'S THE CASE,

THIS ENTIRE COMPLEX COULD
HAVE BEEN ONE OF THE SITES

WHERE GREAT BRITAIN DEVELOPED
ITS FIRST NUCLEAR WEAPON.

Narrator: FOR MANY PEOPLE,

THE ATOMIC AGE STARTS IN 1945

WHEN THE ENOLA GAY DROPS

THE LITTLE BOY BOMB
OVER HIROSHIMA.

YET THE JOURNEY TOWARDS
NUCLEAR OBLIVION BEGINS

WITH A DISCOVERY MADE IN
ENGLAND DECADES EARLIER.

IN MANY WAYS,
ENGLAND IS THE BIRTHPLACE

OF THE ATOMIC BOMB.

IT WAS ACTUALLY A BRITISH
PHYSICIST WHO

WAS THE FIRST ONE
TO SPLIT AN ATOM.

Narrator: THAT PHYSICIST
IS ERNEST RUTHERFORD,

WHO, IN 1917, BECOMES
THE FIRST PERSON TO CREATE

AN ARTIFICIAL NUCLEAR REACTION.

BY THE DAWN OF WORLD WAR II,

BRITISH ATOMIC RESEARCH
LEADS THE WORLD.

BUT FEARING A NAZI INVASION,

PRIME MINISTER WINSTON CHURCHILL
DECIDES TO ACCELERATE

HIS NUCLEAR BOMB PROGRAM BY

COLLABORATING WITH THE U.S.
ON THE MANHATTAN PROJECT.

Silbey: CHURCHILL HANDED OVER
BRITISH ATOMIC SECRETS

TO THE AMERICANS.

UNFORTUNATELY,
THE AMERICANS WERE NOT

QUITE AS GENEROUS IN RETURN.

Narrator: WHEN THE WAR ENDS,
PARANOID ABOUT SHARING

THE SECRETS OF
THEIR NEW MEGA WEAPON,

[ EXPLOSION BLASTS ]

THE U.S. CLASSIFIES
ITS ATOMIC RESEARCH PROGRAM.

Announcer: THE ATOM BOMB
CAREFULLY SCREENED, IS WHEELED

TO THE B-29 THAT'S ABOUT
TO CARRY IT TO BIKINI.

NOT EVEN A GLIMPSE OF
THIS EPOCH-MAKING MISSILE

IS PERMITTED.

WASHINGTON DECIDED TO CUT
THE BRITISH OUT OF THE PLAN

COMPLETELY AND KEEP
THE TECHNOLOGY FOR THEMSELVES,

WHICH LEFT LONDON NO OTHER
CHOICE THAN TO HAVE TO START

THE PROGRAM AGAIN
FROM SCRATCH.

Narrator: IN 1949, PRESSURE
ON THE BRITISH NUCLEAR PROGRAM

INCREASES WHEN RUSSIA
BECOMES THE SECOND

GLOBAL NUCLEAR POWER.

[ EXPLOSION BLASTS ]

[ INDISTINCT TALKING ]

THE UNITED KINGDOM SUDDENLY
FELT EXTREMELY VULNERABLE.

[ INDISTINCT TALKING ]

AND IT LEADS ONE BRITISH
POLITICIAN TO MAKE THE STATEMENT

THAT WE NEED AN ATOMIC BOMB,

AND WE NEED IT TO HAVE A BLOODY
UNION JACK ON TOP OF IT.

Narrator:
DECLASSIFIED COLD WAR FILES

REVEAL THE BRITISH GOVERNMENT
BUILDS THE SITE IN

THE IMAGE, CALLED ORFORD NESS,
TO COUNTERACT

THE COMMUNIST NUCLEAR THREAT.

Announcer: AND NOW,
AS THE MOMENT OF DETONATION

DRAWS NEAR,
THE ATMOSPHERE IN

THE CONTROL ROOM BECOMES
INCREASINGLY TENSE.

THE BRITISH NUCLEAR PROGRAM
DID ULTIMATELY SUCCEED.

IN OCTOBER OF 1952,
BRITAIN EXPLODED

ITS FIRST NUCLEAR WEAPON.

[ TICKING NOISES ]

[ EXPLOSION BLASTS ]

THAT EXPLOSION ANNOUNCED

BRITAIN AS THE THIRD
NUCLEAR POWER IN THE WORLD.

Narrator: BRITAIN'S FIRST
OPERATIONAL NUCLEAR WEAPON IS

A 10,000-POUND FREEFALL BOMB
CODE NAMED BLUE DANUBE.

THE PRECISE DETAILS OF ORFORD
NESS'S ROLE IN ITS DEVELOPMENT

REMAIN CLASSIFIED,

YET ITS DECAYING STRUCTURES
OFFER CLUES.

THIS LOOKS LIKE
A BALLISTIC STOP WALL.

WHAT THEY PROBABLY DID FOR
THE TEST IS THEY WOULD MOUNT

CAMERAS ON THERE

AND BE ACTUALLY ABLE TO FILM
THE IMPACT OF MISSILE CASINGS

AND SEE HOW THEY REACTED.

Moran: AT ORFORD NESS,
WEAPONS ARE TESTED WITH ALL

THE CONDITIONS THAT MIGHT
ACTUALLY OCCUR BEFORE THEY'RE

DETONATED -- VIBRATION,

EXTREME TEMPERATURES, SHOCK,
G FORCES, AND IMPACT.

[ EXPLOSION BLASTS ]

Narrator: IN 1958,
AFTER YEARS OF MISTRUST,

BRITAIN AND THE U.S.
REESTABLISH RELATIONS

AND BEGIN CONDUCTING
ATOMIC TESTS TOGETHER.

OVER THE FOLLOWING YEARS,
THE STRANGE TEMPLES TO SCIENCE

WHICH ESTABLISHED BRITAIN
AS A NUCLEAR POWER

SLOWLY FADE INTO OBSCURITY.

**

NATURE IS TAKING OVER.

IT HAS SORT OF
A GRAVEYARD FEEL TO IT.

BUT IF YOU REALLY
THINK ABOUT IT,

THIS PLACE WAS THE FRONT LINE
FOR THE COLD WAR.

**

COMING UP, ICE WARS --

THE DAWN
OF THE SUPER SOLDIER.

YOU WOULDN'T WANT THIS
TECHNOLOGY TO FALL INTO

THE WRONG HANDS.

Narrator: AND THE MEGA BLAST
THAT CHANGED HISTORY.

THE DETONATION IS JUST
ABSOLUTELY CATASTROPHIC.

Narrator:
NOVEMBER 8, 2019.

THE WorldView-3
SATELLITE SCANS

THE SEEMINGLY ENDLESS
ICE SHEETS OF ANTARCTICA.

Kourounis: YOU'VE GOT
THIS WHITE BACKGROUND OF ALMOST

INFINITE SNOW,

BUT RIGHT IN THE MIDDLE IS
THIS BLOOD RED SPLOTCH

AS IF SOMEONE HAS TAKEN
A GIANT KNIFE

AND DRIVEN IT INTO
THE HEART OF THE ICE.

Narrator: INVESTIGATORS
TAKE A CLOSER LOOK.

THE SHADOW MAKES YOU REALIZE
IT'S A VERY LARGE STRUCTURE.

I WOULD ASSUME
IT'S AN ANTARCTIC BASE.

Narrator: THERE ARE AROUND 70
RESEARCH STATIONS IN ANTARCTICA,

BUT LAND RECORDS REVEAL
THERE IS SOMETHING STRANGE

ABOUT THIS ONE.

THERE ARE ACTUALLY SEVEN NATIONS
THAT HAVE CLAIMS TO ANTARCTICA,

AND THE PORTION WE'RE LOOKING
AT IN THESE IMAGES IS ACTUALLY

CONTROLLED BY AUSTRALIA.

BUT IT TURNS OUT THIS ISN'T
AN AUSTRALIAN BASE.

Narrator:
FOR INTELLIGENCE ANALYSTS,

THE BASE'S COLOR IS SIGNIFICANT.

WHEN WE REFERENCED
THE RECORDS OF

THOSE FACILITIES
IN ANTARCTICA,

CHINA'S BASES
DO APPEAR AS BRIGHT RED.

SO WHY IS A CHINESE BASE IN

THE MIDDLE OF ANTARCTICA
ON AUSTRALIAN TERRITORY?

Narrator:
ACCORDING TO THE CHINESE,

THE FACILITY HOUSES
A 50-FOOT TELESCOPE,

WHICH WILL HELP STUDY EARTH-LIKE
PLANETS AND DARK MATTER.

YET IMAGE ANALYSIS SUGGESTS

THE STRUCTURE MAY SERVE
A DIFFERENT PURPOSE.

WE'RE NOT REALLY SEEING THINGS
ASSOCIATED WITH ASTRONOMY.

THERE'S NO LARGE TELESCOPE.

THERE'S NO HEAVY MACHINERY
FOR CREATING ONE.

IT MAKES ME WONDER
WHAT'S REALLY HAPPENING HERE.

Narrator:
THE BASE IS ONE OF THREE

THAT CHINA HAS CONSTRUCTED
IN THE REGION.

IT HAS NEVER BEEN INSPECTED
BY AUSTRALIAN OFFICIALS.

WHAT TYPE OF EXPERIMENTATION
IS BEING CONDUCTED?

THERE IS SO MUCH SPECULATION
ABOUT THIS FACILITY,

BUT SO LITTLE OVERSIGHT.

Narrator: MOLECULAR BIOLOGIST
ADAM RUBEN UNCOVERS EVIDENCE

THAT COULD EXPLAIN BEIJING'S

APPARENT FASCINATION WITH
THESE VAST EXPANSES

OF ICE AND SNOW.

I'VE COME ACROSS A SERIES
OF REPORTS THAT INDICATE

THE CHINESE ARE INTERESTED IN
BIOPROSPECTING IN ANTARCTICA.

THIS IS BASICALLY THE SEARCH
FOR ORGANISMS THAT

MIGHT CREATE MOLECULES THAT
COULD HAVE COMMERCIAL USE.

Narrator:
FROM MEDICINES TO TECHNOLOGY,

BIOPROSPECTING
HAS POTENTIALLY

REVOLUTIONARY COMMERCIAL
AND INDUSTRIAL APPLICATIONS.

Ruben: A LOT OF THE MEDICINES
AND CHEMICALS WE USE

ARE DESIGNED BASED ON THINGS
THAT LIVING CREATURES MAKE.

THIS KIND OF TECHNOLOGY
IS FASCINATING,

BUT YOU HAVE TO BE
CAREFUL WITH IT.

[ PENGUINS CALLING ]

Narrator: FOR BIOPROSPECTORS
LOOKING TO EXPLOIT NATURE FOR

TECHNOLOGICAL GAIN,

ANTARCTICA IS A 5.5-MILLION-
SQUARE-MILE GOLDMINE.

THE ORGANISMS OBVIOUSLY HAVE
SOME REALLY COOL PROPERTIES

THAT ALLOW THEM TO LIVE AT
SUCH EXTREME TEMPERATURES.

Narrator: ANTARCTICA IS
THE COLDEST, DRIEST,

WINDIEST, AND HIGHEST
CONTINENT ON EARTH.

IT MEANS THAT ORGANISMS HERE
HAVE DEVELOPED GENES THAT

ENABLE THEM TO THRIVE IN
THE HARSHEST

CONDITIONS IMAGINABLE.

THE GENES THAT WOULD POWER
THESE ORGANISMS ARE ONES

THAT WOULD BE OF GREAT USE
TO A GENETIC ENGINEER,

AND THE CHINESE ARE VERY
INTERESTED IN GETTING THOSE.

Ruben: THE MOST CONCERNING THING
THAT ANYONE COULD DO WITH

THIS TECHNOLOGY WOULD BE TO
USE IT ON HUMANS WITHOUT PROPER

REGULATORY OVERSIGHT.

Narrator: INTELLIGENCE HAS
RECENTLY EMERGED THAT BEIJING

IS POURING INCREASING AMOUNTS

OF ITS $250 BILLION
DEFENSE BUDGET

INTO BIOTECHNOLOGY.

AT THE FOREFRONT
OF THIS RESEARCH IS

A REVOLUTIONARY GENETIC
EDITING TOOL CALLED CRISPR.

Kourounis:
IT'S ALL ABOUT SPLICING

THE BUILDING BLOCKS
THAT MAKE UP,

WELL, US,

AND IT HAS THE POTENTIAL
TO CURE ALL KINDS OF

GENETIC DISEASES.

AS PROMISING AS THAT IS,

YOU WOULDN'T WANT
THIS TECHNOLOGY TO FALL

INTO THE WRONG HANDS.

Narrator: IN 2018, A CHINESE
BIOPHYSICIST SUCCESSFULLY

AND ILLEGALLY CREATES

THE WORLD'S FIRST GENE-EDITED
BABIES USING CRISPR TECHNOLOGY.

THE NIGHTMARE SCENARIO IS
THAT IT COULD ALSO BE USED

TO SPLICE SUPERGENES
FROM ANTARCTIC ORGANISMS

INTO HUMAN EMBRYOS.

IF YOU HAVE AN ORGANISM
THAT CAN SURVIVE THOSE HARSH

WEATHER CONDITIONS,

IN THEORY, THAT NEW ORGANISM
WILL HAVE THAT CAPABILITY.

**

Narrator: FOR THE MILITARY,
THESE GENETIC

CAPABILITIES WOULD BE
GAME-CHANGING.

YOU COULD ACTUALLY
END UP WITH A UNIT

THAT IS COMPRISED OF SOLDIERS
WITH INCREDIBLE STRENGTH,

INCREDIBLE ENDURANCE,
ON THE BATTLEFIELD.

Narrator: THE AGE OF
THE SUPER SOLDIER HAS BEGUN.

Carter: WHAT BETTER PLACE
IN THE WORLD THAN

THE ANTARCTIC TO DO
THIS KIND OF RESEARCH?

IT SOUNDS A LOT LIKE
SCIENCE FICTION,

BUT IT REALLY ISN'T.

Narrator: COMING UP, THE LOST
EMPIRE OF THE CLOUD WARRIORS.

JUST BLOWS UP RIGHT
IN FRONT OF THEM.

AN EARTH OBSERVATION
SATELLITE ORBITING OVER

THE PERUVIAN ANDES CAPTURES

AN ANOMALY FAR BELOW.

Paul: WHAT WE SEE
IN THESE IMAGES

IS A VERY LUSH
GREEN LANDSCAPE.

WHAT'S UNUSUAL IS,
IN THIS CLEARING,

WE SEE A CLUSTER OF
CIRCULAR STRUCTURES.

Krueger: WHEN YOU ZOOM IN
REALLY CLOSELY,

YOU CAN SEE THAT THESE ARE
ACTUALLY WALLS IN A STATE OF

GREAT DETERIORATION.

SO THEY MUST BE
REALLY, REALLY OLD.

THE QUESTION IS, WHY WOULD
SOMEBODY BE BUILDING

BUILDINGS LIKE THIS WAY
HIGH UP IN THE ANDES?

**

Narrator: FEW ANCIENT PEOPLES
SUCCEEDED IN CARVING OUT

AN EXISTENCE IN THE LOW OXYGEN
ATMOSPHERE OF THE HIGH ANDES.

THERE'S ONLY ONE PEOPLE
THAT WE KNOW IN THIS REGION

WHO ADAPT TO THAT
HIGH ALTITUDE LIFESTYLE.

WE CALL THEM
THE CHACHAPOYA.

Narrator: THE CHACHAPOYA,
ALSO CALLED THE CLOUD WARRIORS,

RULE THESE JUNGLES AND MOUNTAINS
BETWEEN THE NINTH

AND FIFTEENTH CENTURIES A.D.

ARCHAEOLOGISTS HOPE THIS SITE

REVEALED FROM SPACE
COULD SHED NEW LIGHT

ON THIS POWERFUL,
YET MYSTERIOUS, CIVILIZATION.

WE KNOW VERY LITTLE ABOUT
THIS CULTURE,

BUT IF THEY WERE BUILT BY
THE CHACHAPOYA, THESE CIRCULAR

STRUCTURES COULD BE
1,000 YEARS OLD OR MORE.

Narrator: THE CLOUD WARRIORS
LEAVE NO WRITTEN RECORDS.

BUT STUDIES SUGGEST
THEY ARE HEADHUNTERS,

MACABRE TROPHIES OF
THE MANY TRIBES THEY CONQUERED.

THEY BUILD GIANT SARCOPHAGI INTO
CLIFFS TO HONOR THEIR DEAD

AND TERRIFY THEIR ENEMIES.

SOME OF THE LEGEND REFERS TO
SHAMANS HAVING AN ABILITY TO

SHAPESHIFT INTO DIFFERENT
TYPES OF ANIMAL FIGURES.

SO THEY WERE DEFINITELY FEARED
BY OTHER PEOPLE IN THE REGION.

Narrator: CLOSE TO THE SITE
IN THE IMAGE,

WROUGHT IN STONE,
CAN BE FOUND

EVIDENCE OF
THE CLOUD WARRIORS'

IMMENSE POWER AND SKILL.

KUELAP IS
THE CHACHAPOYAS' LARGEST

MOUNTAIN CITADEL.

IT'S EVEN BIGGER THAN
THE FAMOUS MACHU PICCHU.

Narrator: AT ITS HEIGHT,
THE CLOUD WARRIORS' EMPIRE

SPREADS ACROSS
25,000 SQUARE MILES

AND NUMBERS 300,000 PEOPLE.

BUT AFTER 600 YEARS,
IT COMES TO A VIOLENT DEMISE.

BY THE END OF
THE FIFTEENTH CENTURY,

AS POWERFUL AND MIGHTY
AS THE CHACHAPOYA ARE,

THEY CAN'T RESIST THE FLOOD TIDE
OF THE INCA.

[ SHOUTING AND BATTLE NOISE ]

Paul: THESE TWO INCREDIBLE
WARRIOR CULTURES

CLASHED WITH ONE ANOTHER.

ULTIMATELY, THE MILLIONS
OF PEOPLE BEHIND

THE INCAN EMPIRE PREVAILED
AND DEFEATED THE CHACHAPOYA.

Narrator: YET WHEN INVESTIGATORS
VISIT THE SITE REVEALED

FROM THE SKIES,

THEY UNCOVER ANOTHER STRANGE
CHAPTER IN THE STORY OF

THE CLOUD WARRIORS.

Paul:
ARCHAEOLOGISTS DISCOVERED

AN ENTIRELY DIFFERENT
TYPE OF STRUCTURE

ON A GRID LAYOUT
WITH VERY STRAIGHT LINES.

WHAT'S REALLY STRANGE
IS IT'S MUCH MORE

Krueger: SIMILAR TO THE LAYOUT
OF A ROMAN RUIN.

WHAT IS A ROMAN RUIN DOING
IN THE MIDDLE OF THE ANDES?

IT REALLY BOGGLES THE MIND.

Narrator: SOME HISTORIANS CLAIM
THAT THE ROMANS VISIT

THE AMERICAS OVER 1,000 YEARS
BEFORE CHRISTOPHER COLUMBUS.

YET PATRICK HUNT
SUSPECTS THE MYSTERY RUINS

ARE A LEGACY OF ANOTHER
EUROPEAN NATION.

SOMETHING HISTORY-CHANGING
HAPPENS AT THE END

OF THE FIFTEENTH
AND THE BEGINNING

OF THE SIXTEENTH CENTURY --

SPAIN, THE CONQUEST
OF THE NEW WORLD.

Narrator: AS THE SPANISH MOVE
ACROSS SOUTH AMERICA,

THE CHACHAPOYA LEARN OF
THE CONQUISTADORS' PLANS TO

ATTACK THE INCA.

Hunt: THE CHACHAPOYA SEE
THE POSSIBILITY OF REVENGE

AGAINST THEIR INCA
CONQUERORS -- GLEEFULLY,

THEY JOIN THE RANKS
OF THESE CONQUISTADORS

TO TAKE DOWN THE INCA.

[ SHOUTING AND BATTLE NOISE ]

Narrator:
WITH HELP FROM THE CHACHAPOYA,

THE SPANISH CONQUEST OF
THE INCA IS SWIFT AND BRUTAL.

BUT FOR THE COLLABORATORS,
VICTORY IS SHORT-LIVED.

Paul: WITH THE INCA
PRIMARILY DEFEATED,

THE CONQUISTADORS
TURN ON THE CHACHAPOYA,

THE VERY PEOPLE THAT HAD
THROWN THEIR SUPPORT

BEHIND THE SPANISH.

Narrator: HISTORICAL DOCUMENTS
REVEAL THAT THESE STRANGE

ROMAN RUINS ARE A LEGACY OF
THE SPANISH SUBJUGATION

OF THE CLOUD WARRIORS.

KING PHILIP II OF SPAIN

ISSUED A SERIES OF LAWS
CALLED THE LAWS OF THE INDIES,

AND HE DECREED
THAT ALL NEW TOWNS IN

THE AMERICAS SHOULD BE BUILT
FOLLOWING A ROMAN PATTERN.

Narrator: DURING A DECADE OF
CULTURAL OPPRESSION,

THE SPANISH FORCIBLY RESETTLE
AROUND 1.5 MILLION PEOPLE

INTO THESE ROMAN-INSPIRED
TOWNS CALLED REDUCCIONES.

THE CHACHAPOYA
FIND THEMSELVES

MERCILESSLY ENSLAVED.

THIS VERY TERM
REDUCCIONES MEANS

THE REDUCTION OF A PEOPLE.

Narrator:
THE CONQUISTADORS FORCED

THE FORMER PROUD WARRIOR PEOPLE
TO WORK IN GOLD

AND SILVER MINES AND SHIP
THE RICHES OF THEIR FORMER

EMPIRE BACK TO SPAIN.

[ CHURCH BELL TOLLS ]

Hunt: THE ABSORPTION OF
THE WEALTH IS SUCH THAT YOU CAN

HARDLY GO INTO ANY RENAISSANCE
OR BAROQUE CHURCH

IN SPAIN AND NOT SEE ALTARS
COVERED IN PERUVIAN GOLD.

Narrator:
REDUCED TO SERVITUDE,

VANISH INTO THE MOUNTAINS

AND JUNGLES,

LEAVING BEHIND THE STRANGE
PATTERNS SEEN FROM SPACE.

[ TYPING NOISES ]

Narrator: FORMER INTELLIGENCE
OFFICER TREVOR ALBERTSON

RECOGNIZES THE STRUCTURES.

YOU CAN SEE THERE'S
A CEMENT FACE TO IT,

AND THEN IT'S COVERED
BY GRASS.

THAT'S EXACTLY WHAT
AN AMMUNITION DUMP LOOKS LIKE.

Narrator: THE SIZE OF
THE AMMO DUMP SUGGESTS

IT'S BIG ENOUGH TO STASH

TENS OF THOUSANDS OF
TONS OF HIGH EXPLOSIVES

AND SITS NEXT TO
A HIGHLY-POPULATED SUBURB.

CLOSER ANALYSIS REVEALS
SOMETHING EVEN WEIRDER.

ON THESE INTERSECTING ROADS,

THERE ARE FOUR-WAY STOPS,

AND I SEE CIVILIAN VEHICLES
ON THEM.

Narrator: UNSURPRISINGLY,
THE U.S. MILITARY

DOES NOT ALLOW CIVILIANS

TO DRIVE AROUND
ITS WEAPONS FACILITIES.

SO WHAT ARE
THESE CARS DOING IN

WHAT AMOUNTS TO A MASSIVE
MILITARY AMMUNITION DUMP?

Narrator: ALBERTSON LEARNS
THAT THIS BASE DOES HAVE

A HISTORY OF CATASTROPHIC
ACCIDENTAL EXPLOSIONS.

Albertson:
THIS SITE IS RIGHT NEXT TO

A FACILITY KNOWN
AS PORT CHICAGO,

FAMOUS FOR A DISASTER
THAT OCCURRED THERE

DURING WORLD WAR II.

Narrator: THE U.S. MILITARY
BUILDS PORT CHICAGO IN 1942.

MANY OF ITS SAILORS ARE
TASKED WITH

LOADING SUPPLY SHIPS WITH
WEAPONS AND HIGH EXPLOSIVES.

SHORT OF COMBAT,
THIS IS ONE OF THE MOST

DANGEROUS JOBS IN THE MILITARY.

Narrator: MUCH OF THE LOADING
IS DONE BY SOME OF

THE 1.2 MILLION
AFRICAN-AMERICANS

RECRUITED TO FIGHT NAZI TYRANNY
DURING WORLD WAR II.

YET AT PORT CHICAGO,
AS ELSEWHERE IN THE MILITARY,

THEY ENDURE DAILY
OPPRESSION AND RACISM.

Hymel:
THIS IS A SEGREGATED MILITARY.

THEY'RE LOOKED DOWN UPON.

THEY'RE NOT TRAINED
IN WHAT THEY'RE DOING.

Narrator:
WHITE OFFICERS SET ALMOST

IMPOSSIBLE QUOTAS
FOR LOADING BOMBS

AND EVEN ENCOURAGE COMPETITION
BETWEEN THE SAILORS.

IT'S A LEVEL OF PREJUDICE
THAT'S GONNA LEAD TO DISASTER.

Narrator: DURING THE NIGHT OF
JULY 17, 1944 HUNDREDS OF PORT

CHICAGO SAILORS ARE RACING TO
PACK TWO SHIPS WITH MUNITIONS.

Munoz: THEN ALL OF A SUDDEN,

THEIR WORLD JUST BLOWS UP
RIGHT IN FRONT OF THEM.

[ EXPLOSION BLASTS ]

THE ENTIRE CONTENTS
OF BOTH SHIPS DETONATES.

[ EXPLOSION BLASTS ]

THE DETONATION IS JUST
ABSOLUTELY CATASTROPHIC.

IT'S EQUIVALENT
TO LIKE 6,000 TONS

OF TNT EXPLODING
IN ONE PLACE.

Narrator: THE BLAST IS FELT
50 MILES AWAY.

Wawro: THE PIER DISINTEGRATES.
THE SHIPS DISINTEGRATE.

ALL THAT'S LEFT OF
ONE OF THE SHIPS IS

A PIECE OF WRECKAGE THE SIZE
OF A SUITCASE.

CLAIMS 320 LIVES.

15% OF ALL AFRICAN-AMERICANS
KILLED DURING

WORLD WAR II DIE
IN THIS SINGLE BLAST.

Hymel: THE AFRICAN-AMERICAN
SAILORS THAT SURVIVE,

THEY'RE TRAUMATIZED BY
WHAT THEY'VE GONE THROUGH.

AND YET, JUST A FEW WEEKS
LATER, THE U.S. NAVY

TASKS THEM WITH LOADING

ANOTHER SHIP
IN A DIFFERENT LOCATION.

WELL, THEY REFUSE.

Narrator: EVEN WHEN THREATENED
WITH THE DEATH PENALTY,

50 SAILORS REFUSE
TO OBEY THE ORDER.

Albertson: IT LEADS TO WHAT
AMOUNTS TO A MUTINY.

THESE MEN ARE THEN
COURT-MARTIALED IN ONE

OF THE LARGEST SINGLE COURT-
MARTIALS IN NAVAL HISTORY.

Narrator: THE SO-CALLED
PORT CHICAGO 50 ARE EACH

SENTENCED TO UP TO
15 YEARS HARD LABOR.

[ TYPING NOISES ]

THE VERDICT SENDS SHOCKWAVES
THROUGH AMERICA.

IT REALLY SHINES A SPOTLIGHT
ON THE DIFFERENT

TREATMENT OF AFRICAN-AMERICAN
TROOPS VERSUS WHITE TROOPS.

Albertson: WHAT STARTS AS A VERY
TRAGIC DISASTER ENDS UP

BECOMING THE CATALYST FOR VERY
MEANINGFUL AND POSITIVE CHANGE.

THE NAVY IS ONE OF
THE FIRST INSTITUTIONS

IN THE UNITED STATES
TO DESEGREGATE.

Narrator: YET THE MYSTERY
REMAINS OF WHY

A BASE THAT HAS
WITNESSED SUCH

A MASSIVE EXPLOSION APPEARS
TO HAVE CIVILIAN CARS WEAVING

AROUND ITS AMMO BUNKERS.

Hymel: MUNITIONS IS
A DEADLY BUSINESS,

AND THAT'S SOMETHING PEOPLE
IN THIS AREA KNOW

A LITTLE BIT TOO WELL.

Narrator: THE ROAD MARKINGS
AND VEHICLES APPEAR IN 2014,

A DATE THAT CORRESPONDS
WITH A SECTION OF

THE FACILITY BEING
DECOMMISSIONED AND LEASED

TO LOCAL COMPANIES.

Kourounis: THIS PLACE IS REALLY
CLOSE TO SILICON VALLEY,

AND PUTTING TWO
AND TWO TOGETHER,

AUTONOMOUS VEHICLES
ARE ONE OF

THE HOTTEST TECHNOLOGIES
RIGHT NOW.

PERHAPS THIS IS AN AUTONOMOUS
CAR-TESTING GROUND.

Narrator:
THE AUTONOMOUS CAR INDUSTRY

HOPES TO CUT ROAD DEATHS
BY OVER 90 PERCENT.

BUT THERE ARE STILL YEARS
OF TESTING TO COMPLETE.

YOU DON'T START BY DOING
YOUR TESTS IN THE MIDDLE

OF MANHATTAN.

YOU NEED A TESTING GROUND
THAT HAS, WELL,

EXACTLY WHAT THIS SITE HAS --

OPEN ROADS, LOTS OF SPACE,
STRAIGHTAWAYS, CURVES.

Narrator:
THE BASE THAT EXPERIENCED

ONE OF THE DEADLIEST
DISASTERS IN U.S. HISTORY

MAY YET SAVE
COUNTLESS LIVES IN THE FUTURE.

Kourounis: HOPEFULLY,

THE NEW TENANTS OF THIS LAND
WON'T FORGET THE MEN WHO

LIVED AND DIED ON THIS PLACE
SO MANY YEARS AGO.

Narrator: COMING UP,

WHERE RELIGION MEETS
THE UNDERWORLD.

THESE REPRESENT STONEMASONRY
ON AN EPIC SCALE.

Narrator:
OCTOBER 12, 2015.

HUNDREDS OF MILES ABOVE HENAN
PROVINCE IN CENTRAL CHINA,

A SATELLITE CAPTURES
THIS IMAGE.

Mosher: THIS IMAGE IS
REALLY INTERESTING.

IT LOOKS LIKE THERE ARE
PLOTS OF FIELDS,

BUT IN THE MIDDLE OF ALL THAT

ARE THESE STRANGE AND REALLY
BIG RECTANGULAR STRUCTURES.

Narrator: ANALYSIS REVEALS

THAT THESE ARE NO ORDINARY
STRUCTURES.

Ruben: WHEN YOU LOOK CLOSER,
YOU SEE THESE BUILDINGS

ARE NOT COMING
UP OUT OF THE GROUND.

THEY'RE SINKING DOWN.

SO THE QUESTION IS, WHO DUG
THESE PITS AND WHY?

Narrator:
MARK HORTON HAS A THEORY.

IT MAY WELL BE THAT
THESE CHINESE PIT STRUCTURES

COULD HAVE HAD
A RELIGIOUS PURPOSE.

THE IDEA THAT YOU'RE CARVING
OUT LIVING ROCK

IS A POWERFUL IDEA IN MANY
DIFFERENT RELIGIONS.

Narrator: IF THESE ARE
RELIGIOUS STRUCTURES,

THE ARCHAEOLOGIST THINKS THEY
COULD BE MANY CENTURIES OLD.

WHEN I SEE A PIT LIKE THIS,

THIS ACTUALLY REMINDS ME OF
A TRADITION OF ROCK-CUT CHURCHES

THAT ONE FINDS IN ETHIOPIA.

Narrator: IN A MOUNTAINOUS
REGION IN THE HEART OF ETHIOPIA

STAND AROUND A DOZEN
SUBTERRANEAN CHURCHES.

THEY HAVE DUG A GREAT BIG
SQUARE PIT,

AND LEFT INSIDE A PILLAR,
A PLUG OF THE ROCK,

WITHIN THIS IS THEN
CONSTRUCTED A CHURCH.

Narrator: STONEMASONS HAVE
CARVED ENTIRE FLOORS, ROOFS,

CAVES, AND CATACOMBS INTO
THESE GIANT COLUMNS OF ROCK.

THESE CHURCHES REPRESENT
STONEMASONRY ON AN EPIC SCALE.

THE WALLS ARE MADE OF STONE.
THE PILLARS WERE MADE OF STONE.

THE WHOLE THING IS SCULPTED
OUT OF THE LIVING ROCK.

Narrator:
WORK ON THE CHURCHES BEGINS

IN THE SEVENTH CENTURY A.D.,

THE SAME TIME CHRISTIANITY
IS INTRODUCED TO CHINA.

YET FURTHER EXAMINATION
SUGGESTS THE PITS IN

THE IMAGE DO NOT SERVE
A SIMILAR PURPOSE.

LOOKING AT THIS MORE CLOSELY,
I SEE SIGNS OF HUMAN ACTIVITY,

POSSIBLY SOME COLORED ROOFS.

IT REALLY LOOKS
LIKE THIS COULD

BE SOMEWHERE
THAT PEOPLE ARE DWELLING.

Narrator: A STUDY OF
LOCAL HISTORIC RECORDS

YIELDS FURTHER CLUES.

THESE ARE WHAT'S KNOWN
AS YAODONGS,

WHICH ARE UNDERGROUND CAVE
HOUSES DUG INTO EARTH

AND INTO CLIFFS.

YAODONGS, WHICH TRANSLATES
AS "HOUSE CAVE,"

FIRST APPEAR DURING THE XIA
DYNASTY AROUND 2000 B.C.

OFTEN HEWN OUT OF ROCK,

A COURTYARD OR ENTRANCE CAN
GIVE WAY TO MULTIPLE

CONCEALED ROOMS.

SOME OF THESE ARE
HUNDREDS OF YEARS OLD

AND HAVE HOUSED GENERATIONS
OF THE SAME FAMILY.

Narrator: YAODONGS HAVE PLAYED
A ROLE IN SOME OF

THE MOST PIVOTAL EVENTS
IN CHINESE HISTORY.

IN 1934, MAO ZEDONG LEADS
100,000 PEOPLE ON A YEAR-LONG,

6,000-MILE FLIGHT ACROSS CHINA,
THE SO-CALLED "LONG MARCH."

HIS RED ARMY SOLDIERS
THEN DIG OUT

CAVE HOUSES
NEAR YAN'AN CITY,

IN WHICH MAO FORMULATES MUCH
OF HIS COMMUNIST IDEOLOGY.

THESE AREN'T JUST
HOLES IN THE GROUND.

THESE ARE VERY
ELABORATE DWELLINGS.

Chamberlain: ONE INTERESTING
CHARACTERISTIC OF LIVING IN

THESE CAVE HOUSES IS THAT
IT'S ALMOST LIKE HAVING

A NATURAL AIR CONDITIONER.

THE ENVIRONMENT
IS REALLY HOT IN

THE SUMMER AND VERY COLD
IN THE WINTER,

YET INSIDE, IT REMAINS 50
TO 70 FAHRENHEIT ALL YEAR ROUND.

Mosher: LIVING UNDERGROUND
HAS ITS PERKS,

BUT THESE STRUCTURES ARE VERY
SUSCEPTIBLE TO NATURAL

DISASTERS LIKE FLOODING
AND EARTHQUAKES.

Narrator: IN 1556, THE DEADLIEST
EARTHQUAKE IN HISTORY

HITS THIS REGION,

KILLING 830,000 PEOPLE,
MANY OF WHOM

LIVE IN CAVE HOUSES.

YET DESPITE
THE POTENTIAL PERILS,

THESE ARCHAIC DWELLINGS MAY
PROVE TO BE THE FUTURE OF

URBAN HABITATION.

TWO-THIRDS OF THE WORLD'S
POPULATION IS PREDICTED

TO LIVE IN CITIES
BY THE YEAR 2050.

SO MAYBE STARTING
TO BUILD UNDERGROUND

IS THE WAY TO
SOLVE OVERPOPULATION.

Narrator:
TODAY, ENGINEERS IN CHINA ARE

CONSTRUCTING 21st CENTURY
VERSIONS OF

THESE 4,000-YEAR-OLD HOUSES
FOR FUTURE GENERATIONS OF

SUBTERRANEAN FAMILIES.

AND IN CITIES
AROUND THE WORLD,

MORE AND MORE PEOPLE ARE
MIMICKING THE ANCIENT WAY OF

LIFE REVEALED FROM SPACE.

THERE ARE ACTUALLY PLANS IN
MEXICO CITY FOR SOMETHING

CALLED THE "EARTHSCRAPER,"

WHICH IS LIKE A SKYSCRAPER
BUT BUILT DOWN INTO THE EARTH.

Mosher: IN LOOKING FOR HOW TO
DEVELOP CITIES INTO THE FUTURE

WITH A GROWING POPULATION,
WE'RE INCREASINGLY LOOKING TO

OLD TRADITIONS TO SOLVE
THAT PROBLEM.
