0:00

it is another mystery of the deep

0:03

as hopes fade for the five wealthy

0:06

Titanic tourists who vanished while

0:08

exploring the wreck aboard a mini

0:10

submarine

0:11

one question keeps arising what happened

0:16

it is possible that no one will ever

0:18

know after the sub call Titan suddenly

0:22

went silent hundreds of miles off the

0:24

coast of Canada and around 13

0:27

000 feet underwater beside the Titanic

0:31

on board was a British billionaire one

0:33

of Pakistan's richest men and his son a

0:36

feigned French explorer and the CEO of

0:39

the company running the dive

0:42

they began their Voyage early Sunday

0:44

with 96 hours of oxygen inside the sub

0:47

and have not been heard from since

0:51

submarine experts agree that five

0:54

possible accidents are the most likely

0:56

cause

1:02

perhaps the most obvious explanation is

1:05

that the submersible became Tangled in

1:07

the wreckage of the Titanic itself the

1:11

ship split into two pieces as it sank

1:13

back in 1912 and those sections now lie

1:17

amidst a huge debris field on the seabed

1:20

navigating the wreck is extremely

1:23

dangerous according to those who have

1:25

dived it it is possible that the subs

1:28

pilot got disoriented perhaps after

1:30

Communications were interrupted causing

1:33

the craft to get snagged another

1:36

Explorer has described how a sudden

1:39

undersea current swept his submarine

1:41

into the wreck getting it temporarily

1:44

stuck Titan is equipped with drop

1:46

weights which can be thrown overboard to

1:49

give it extra buoyancy potentially

1:51

freeing it and helping it float to the

1:53

surface but if it is stuck for example

1:57

inside the Titanic there could be little

1:59

the crew would be able to do except wait

2:02

for help a banging noise picked up on

2:06

Sonar could be the trapped crew knocking

2:08

on the hull of the sub to attract

2:10

attention but Rescuers have still been

2:13

unable to find the craft

2:19

Titan could also have suffered a power

2:22

outage or equipment failure the sub

2:25

relies on batteries to power the

2:26

communications and a failure could

2:29

explain why it lost contact with the

2:31

surface

2:32

but they also power the engines the

2:35

lights and the heating

2:37

a catastrophic failure would have left

2:40

the sub dead in the water in complete

2:43

darkness and in freezing temperatures if

2:48

that is the case experts say the cold

2:50

could kill quicker than the lack of

2:53

oxygen questions have been raised over

2:56

the quality of the sub after one

2:58

passenger pulled out over fears the

3:00

company building it were cut in Corners

3:02

he discovered that scaffolding poles

3:05

were being used as ballast and a video

3:07

game controller was being used for

3:09

steering after that he demanded his

3:12

money back an Ocean Gate engineer also

3:15

previously quit over safety concerns

3:17

about the structural Integrity of the

3:19

sub and an industry body wrote a letter

3:22

in 2018 criticizing the company's

3:24

experimental approach losing power would

3:28

make the sub harder to find and there

3:31

will still be the matter of getting it

3:32

back to the surface when its engines

3:34

aren't working they may still be able to

3:37

surface but there is no sign of the

3:40

vessel yet Aleister Grieg a professor of

3:43

marine engineering at the University

3:45

College London said rescue options will

3:48

be extremely limited if the sub is

3:51

without power

3:56

another possibility is that the sub has

3:58

become Tangled on a piece of debris like

4:01

a fishing net thousands of so-called

4:03

ghost Nets are swept around the deep

4:06

ocean after being lost by trawler men

4:09

back in 2005 a Russian submersible

4:12

called as-28 became Tangled on just such

4:16

a net while it was underwater off the

4:18

Kamchatka peninsula in Far Eastern

4:20

Siberia the net got caught in its

4:23

propellers and caused it to sink to the

4:25

seabed with a British underwater drone

4:27

brought in to cut the netting and free

4:30

it all seven crew members made it safely

4:33

to the surface two days later

4:37

but they were stuck under just a few

4:39

hundred feet of water compared to the

4:42

Titans 13

4:44

000 to cut the craft free Rescuers will

4:47

first have to find it and sonar is not

4:49

good at distinguishing the sub from the

4:52

wreckage of the Titanic scattered around

4:54

it and even if it can be cup free the

4:57

Titan will still have to make it back to

4:59

the surface on its own because

5:01

transferring the crew to another vessel

5:03

at that depth

5:05

is impossible

5:09

[Music]

5:10

after the submersible suddenly stopped

5:13

communicating with no explanation a

5:15

catastrophic implosion of the vessel has

5:18

become a leading theory G Michael Harris

5:22

an experienced Titanic Explorer fears

5:25

that is exactly what happened ten

5:27

thousand feet down where the pressure is

5:30

350 times greater than at the surface

5:34

when a submarine's hull fails at depth

5:36

the pressure of the ocean will almost

5:38

instantly crush it and anyone inside

5:41

even a small fault in the carbon fiber

5:45

and titanium Hull could have caused the

5:47

accident and Titans three previous

5:49

voyages were canceled over fears of

5:52

structural fatigue owners Ocean Gate

5:55

said the vessel which features many

5:57

homemade components such as hardware

5:59

store washers had been repaired since

6:01

and was equipped with a sophisticated

6:04

system to monitor for any problems in

6:07

the hull

6:08

but if an issue had suddenly occurred

6:10

deep underwater it is doubtful the crew

6:14

could have done anything in time to save

6:16

themselves just such an incident

6:18

occurred in 2017 when the Argentinian

6:21

Navy submarine ARA San Juan went missing

6:25

in the San George Gulf the wreck was

6:27

only located a year later scattered deep

6:30

down on the seabed it is not known

6:33

exactly what caused the accident but it

6:36

is thought an electrical failure caused

6:38

it to dive Beyond its Crush depth

6:40

causing an implosion killing all 44

6:43

people on board if that is what happened

6:47

to the Titan then the crew would have

6:49

been killed instantly

6:54

foreign

6:55

Ty is a fire on board perhaps caused by

6:59

water getting into the electrics in 2019

7:02

a blaze broke out inside the battery

7:05

compartment of the Russian submarine

7:07

lusharik while it was a thousand feet

7:10

underwater fighting the fire in

7:12

corridors as narrow as a few feet the

7:15

crew managed to get losherig back to its

7:17

parent submarine which hauled it to the

7:20

surface 14 submariners some of the most

7:23

experienced and highly decorated in the

7:26

whole of the Russian Navy were killed if

7:30

a similar Blaze were to break out on

7:32

board the Titan then the results could

7:34

easily be fatal even if the crew somehow

7:38

got the Flames under control the fire

7:40

could knock out the electronics and eat

7:42

up the oxygen inside the tiny 21-foot

7:46

craft

7:47

there is still a lot we don't know about

7:49

the Titan's fate or the fates of the men

7:52

on board if the craft can somehow get

7:55

itself to the surface then there is hope

7:58

that they can be saved

8:00

but if it is really stuck at the bottom

8:03

of the ocean

8:04

then the chances of finding them alive

8:06

are Slim

8:07

and fading fast
