Tonight,

one of the most chilling aviation mysteries in modern day.

239 people vanish over the Indian Ocean without a trip. With not

enough oxygen feeding the brain, people can't do the simplest thing, let alone

something as complicated as piloting a commercial aircraft.

Now we'll uncover the top theories surrounding the world's most infamous

aircraft. The officials and most of the media convinced themselves that the

satellite data could only mean one thing, that the plane went south.

But they were wrong.

Was it potentially a murder -suicide? There's 227 passengers on board. Any of

them could be responsible.

Can new clues bring us closer to answers?

If the plane isn't flying itself, was it something more sinister?

Because planes don't just disappear.

What really happened to Malaysia Flight 37?

March 8, 2014.

Kuala Lumpur International Airport.

Malaysia Flight 370 sits on the runway, awaiting clearance for takeoff.

The cabin has been secured.

Tray tables and seat backs are in their upright and locked position.

And the flight attendants are ready for what they hope will be a routine flight.

On board, we have 239 people, 227 passengers.

We have 12 crew members.

The 12 crew members are all Malaysian citizens, and up front we have Captain

Shah.

They're headed to Beijing International Airport. It's a routine flight. They

make it twice a day.

March 8th is no exception.

This flight was a flight that Zahari Shah, the captain of the flight, was

familiar with.

Normally, the flight takes about six hours, flying over a handful of

and international waters.

At 1240 a .m., MH370 is cleared for takeoff.

Recording inside the radio chatter back and forth between the aircraft and the

tower shows that everything is routine, mundane even.

At 106.

The plane's computer sends an automated position report.

The transponders are continuously communicating with air traffic control,

relaying information about the flight status.

These messages show up on what's called secondary radar.

At this point, Malaysia 370 is flying on course and has 96 ,000 pounds of fuel

remaining. That's enough fuel for another six to seven hours of flight.

A few minutes later, at 119.

Captain Shaw radios air traffic controls as he transitions from Malaysian to

Vietnamese airspace.

Air traffic control in Kuala Lumpur radios MH370 and says contact Ho Chi

120 .9. Good night.

That means it's time for MH370 to call the Vietnamese controllers on the

frequency given.

Captain Tahari then says, good night, Malaysia 370.

So everything seems fine. The next thing that should happen is that air traffic

controllers in Ho Chi Minh City should hear from Malaysia 370.

But that's not what happens.

The Vietnamese air traffic controller at Ho Chi Minh never hear from that flight

at the scheduled time.

And all of a sudden, the flight transponders aren't responding at all,

disappear from the air traffic controller's screen.

Just 38 minutes into the flight, Malaysia 370 simply disappears from

It's really inexplicable that this aircraft, which had been flying and

transmitting this secondary data all along, would, at this point of

just disappear. The transponder was turned off, and the power was in some

stopped to the transponder. We don't know why it happened.

In modern aviation, air traffic controllers know exactly where their

are through secondary radars and precisely scheduled communications.

So this is something that doesn't happen.

Planes don't just vanish.

Alarm bells immediately ring, and Vietnamese air controllers desperately

to contact the aircraft.

It's just not the case that an airliner would be flying through some nation's

airspace without the controllers knowing who it is, where it is, and why it's

there. That's the way it works. It doesn't happen otherwise.

They tried to contact the cockpit through the satellite phone several

there was no answer.

Then it was clear to them that the aircraft crashed into the sea.

How could this happen so suddenly? Why was there no warning from the pilot? No

mayday? Nothing.

This kicks off what will eventually become the most expensive search in

history.

Everyone, dozens of governments, hundreds of families, all want to know

happened to MH370.

By 5 .30 a .m., a massive search and rescue mission is underway.

They gather 26 countries.

to help with the search by sending 50 ships and about 60 aircraft.

They're looking for anything on the water, wreckage, oil slick.

The search starts naturally where the last transmission from the aircraft

occurred and the last radar trace was found.

It was right on the border between the Gulf of Thailand and South China Sea.

So they do find some oil slick. They test it.

to see if it's aviation fuel, but it's not.

They look at satellite imagery, they see what they think is debris, but they

physically go out there and there's nothing there.

If the aircraft had crashed in that area initially, there'd be debris and oil

slick and plastic and stuff all over the China Sea. It makes no sense that

there's no sign of this airplane anywhere.

After two days of searching, Investigators turn to military radar

Radar on military bases are constantly tracking to see if there's anything in

range.

Malaysia Flight 370 would have been in radar range for bases in Thailand,

Malaysia, and Vietnam.

So their radar records track the plane as well, and they do it slightly

differently. Civilians rely on secondary radar, which requires a signal from the

airplane's transponder.

and that's what they've been using to search for MH370 so far.

But the military uses what's called primary radar.

Primary radar doesn't require a special signal from an airplane.

It sends out radio waves where it bounces off any object that might be in

sky, and it reflects that radio signal back.

It's kind of like echolocation, like a bat would use, but on a large scale.

A Boeing 777 has two transponders.

Specifically in case one fails, the other one is still going to be fine.

So when MH370 vanishes from all the radar, that means both transponders are

at the same time.

After the transponder is turned off.

The secondary radar can't see the airplane anymore. But guess what? The

radar can still see the airplane and continues to track it. It shows the

airplane keeps flying.

Not only does it keep flying, it makes drastic course changes, just as it's

supposed to cross into Vietnamese airspace.

So MH370 turns a little bit to the east, then kind of loops back around. It's

almost like it's turning back, back towards Malaysia.

Then MH370 approaches the Isle of Penang and flies near the Strait of Malacca.

Military radar tracks MH370 for another 230 miles into the Andaman Sea until

the aircraft finally goes out of range.

So in other words, they're looking in the wrong place.

The searchers move their search to the Andaman Sea, but once again, there's

nothing there. So the investigators are closer, but they're clearly not close

enough.

Keep in mind, military radar doesn't pinpoint where this airplane stops

As far as we know, it's still in the air all the way until it goes out of range.

After that, it could have gone in a lot of different directions.

The radar records raise an important question.

Why does the plane fly off course?

Before Malaysia Flight 370 vanishes on March 8, 2014, investigators are shocked

to learn that the plane deviated from its route.

The MH370 planned flight path would have had it flying over the South China Sea

towards Beijing.

But the radar tracking shows it made a series of turns going towards the west.

And it just keeps flying until it goes out of radar range.

Once investigators...

realized the airplane kept flying, every possible theory was out there.

Was it a bomb?

Was it terrorism?

Was it a crime?

Was it something more sinister?

Because planes don't just disappear.

The Internet went crazy, and so did every global government agency.

To some, there's an obvious explanation.

Right away, we know that the aircraft continues flying after the transponders

offline. The aircraft continues on its path and drops off of military radar. We

know that because it's recorded on the military radar until 2 .22 a .m.

Take this radar information and combine it with the fact that the transponder

was cut off just prior to the aircraft veering off course.

Combine that with the fact that there is no emergency distress call made, and it

creates a truly terrifying possibility.

Was it potentially a murder -suicide?

Early in the investigation, they thought they should look very deep into the two

men in the cockpit, which is natural with this type of investigation.

The question is, would anything motivate these two men to bring that aircraft

down? In the cockpit, we have Captain Zahari Shah and First Officer

Fariq Abdul Hamid.

Farik is not fully qualified yet on the 777. However, this is his last flight to

qualify on the 777.

This is a big deal, the realization of a lot of hard work.

He's been with the airline for seven years. He's 27 years old. He's getting

married soon. He has a long career in front of him.

And as a result of that, the investigative bodies rule him out pretty

They don't think he did it.

leaving only one other suspect in the cockpit.

People who subscribe to the murder -suicide theory believe that the

Tsar Shah, deviated from the flight plan and intentionally crashed that airplane

into the Indian Ocean, sadly taking everyone with him.

Investigators dig deeper into Captain Shah, and a search of his home turns up

disturbing clue.

Zara Shaw had a very sophisticated simulator, an actual 777 simulator, in

house. When the investigative bodies pull the data from it, it shows a

of flight paths.

We see that they run out over the Indian Ocean. They just stop.

And ultimately, this is the path that MH370 takes.

It seems as though Captain Shaw had rehearsed this.

So the flight path is somewhat telling in itself.

Captain Shaw is from the island of Penang.

The final maneuver recorded by the military radar was northwest of Penang,

very close to it. It was a clear night, perfect visibility, and this turn gives

him a perfect view, a final view of his home in Penang.

Some people believe that when you...

finally decide to commit suicide, that person has a level of serenity.

So some people believe that this final turn towards Penang was

him waving goodbye to his home.

While all of this evidence paints a damning picture for the pilot, it is not

enough to close the case.

So officially, MH370 is not ruled suicide by pilot because there's no

note, and they determined it's impossible to know what's in his mind.

If the plane wasn't brought down by the pilot or co -pilot, could it be someone

else on the inside?

Investigators turn their attention to the crew.

There's always another possibility that one of the...

cabin crew was trained and familiar with the aircraft and how to get into the

cockpit. So the investigators looked into every one of these crew members,

170 interviews, looked into their bank accounts, social media accounts,

their love life, everything that they could possibly look into, and they

find anything.

Ultimately, There is no substantial evidence to tie the pilot or crew

any wrongdoing. There's absolutely no proof that this was a murder -suicide.

But authorities have this nagging problem.

Why is there no a stress call? What could have happened?

Months after disappearing, the public is desperate for investigators to find

Flight 370.

But with so little evidence, they have their work cut out for them.

One of the most common things that investigators can use to determine the

of the crash is radio chatter.

When there's something unusual happening on the airplane, the flight crew

usually gets on the radio about it.

Whether there's an emergency, they see something out the window, or there's a

passenger acting up, they usually radio that in.

And in this case, there's no radio distress call. We don't have that clue

help us.

Unless the lack of a distress call is the clue.

Based on what we know, I think the most logical explanation is that the airplane

depressurized.

causing everyone on board the aircraft to become unconscious and die from a

of oxygen.

The reason this airplane is flying off course and on an unusual path is because

the pilot is not thinking clearly.

This theory says that a terrible accident happened on board, disabling

and probably the passengers as well.

So the problem with MH370... could have actually started before it left the

craft.

Just before takeoff, maintenance logs show that work was performed on

MH370's oxygen system.

The pressurization system in a 777 handles all the air that everyone

board. And it also handles the cabin pressure.

At a high altitude, the pressure outside the aircraft is very low, too low to

sustain life.

Inside the aircraft, it's pressurized and it's comfortable.

So it's possible that the maintenance fault could have resulted from the work

they did on the pressurization system, essentially causing the aircraft not to

pressurize properly.

It's not terribly uncommon, but if it does happen, someone has to pressurize

aircraft, typically using an emergency procedure.

But what if they didn't?

The last communication with air traffic control was made by Captain Zahari, good

night Malaysia 370.

And that means that he was not flying the aircraft.

On a commercial airliner, there are two pilots, one who is doing the flying and

the other who is doing the monitoring.

The pilot who is making the radio call is not the pilot flying.

That's just the way it works.

Every radio call from the time that Malaysia Flight 370 took off was made by

first officer, Fareed Abdul Hamid.

Captain Shaw was handling the takeoff, getting out of Kuala Lumpur airspace,

sort of the more difficult parts of the flight.

Captain Shaw was a highly experienced airline captain. He had 18 ,000 flight

hours, and he was only 53 years old. That's just 1 ,500 hours less than

Sully Sullenberger had when he famously landed his airliner in the Hudson River.

After takeoff...

We can assume that 38 minutes into the flight, when Captain Shaw's voice is on

the radio, he has handed control of the aircraft to the first officer. Remember,

this was his last flight before becoming qualified on the aircraft.

Now we have the first officer who's operating an aircraft for which he's not

fully qualified.

We have 227 passengers on board, 12 crew members, and the aircraft is climbing,

and we may have a maintenance problem.

A pressurization issue.

This is a dangerous situation.

It can lead to hypoxia.

Hypoxia is a lack of oxygen in the body tissue and brain, which can occur in any

aircraft flying over 16 ,000 feet.

With not enough oxygen feeding the brain, people can't do the simplest

let alone command an airliner.

To be blunt, hypoxia makes you stupid, makes you unable to have rational

thoughts.

At a cruising altitude of 35 ,000 feet, incapacitation due to hypoxia can occur

in less than a minute.

The statistics indicate that for pilots, the time of useful consciousness could

be as low as 15 seconds.

Gradual onset hypoxia has caused numerous airline crashes over the years.

It's a deadly scenario with very little time to react.

There are a number of cases in which an airplane takes off and the pilots have

failed to pressurize the aircraft or the aircraft simply doesn't pressurize.

And because of the nature of hypoxia, there are cases in which pilots got a

cabin altitude warning horn, a warning that the aircraft was not properly

pressurized, and they may not respond to it correctly if their brains are

already lacking oxygen.

Could this have happened aboard MH370?

So at first it makes sense. There is a lack of a mayday call.

There's no call for help.

But under hypoxic conditions, they might not even think they're in danger.

The erratic flight also speaks to a hypoxic event. The pilot turned the

around, heading back to Kuala Lumpur as part of a response to the emergency.

According to radar, the plane makes one last turn.

So the final move made by the first officer could have been to turn the

toward the runway that he knows.

That airport is Langkawi International, set on an island just west of the

Malaysian Peninsula.

This is where he did his flight training.

He's familiar with the terrain. He knows that the runway is long enough to land

a fully loaded 777.

Instead of landing, the plane continues to fly for 230 miles.

So at this point, we think that both crew are incapacitated by hypoxia.

passed out. Then the autopilot takes over.

The aircraft is carrying 239 people who are most likely dead.

And they are flying until that airplane runs out of fuel.

Not everyone is convinced the cabin depressurer.

Could it be something more sinister?

When Malaysia Flight 370 goes missing, investigators from nine countries join

the search, including the United States.

Their biggest challenge is the lack of evidence, almost all of which lies on

that missing airplane.

But several months into their search, authorities get a treasure trove of new

data, and it changes the course of the investigation.

They hear from a company called MRSAT.

They handle satellite data for commercial airlines.

Things like satellite phones in the back of your seat to make calls, TV and

entertainment systems.

These systems are in constant communication back and forth with the

system. It's pretty much just checking in.

While MRSAT has records of this communication, first thing that happens

airplane logs into the MRSAT system at midnight Malaysia time, which is

right before takeoff.

Then the satellite system checks in with the airplane.

on an hourly basis using automatic pings.

It checks in to see, hey, are you there?

And we call that a handshake.

While the aircraft transponder is offline, the Inmarsat communication

keeps going.

It takes months to analyze the data, and at the time, they didn't have the

technology to make full sense of it. But then when they finally figure out the

Inmarsat data, guess what? It shows something incredible.

Previously, the last known contact of the airplane was 2 .22 a .m. when it

disappears from military radar.

And investigators assume that the plane crashed not too long after.

The MR site data shows seven automated pings after 2 .22 a .m. And those pings

go all the way until 8 .19 a .m.

If the plane continues flying for six more hours, where did it go?

So the technology at the time didn't allow them to get a specific location

the Inmarsat ping. All they know is that the plane is within range of a certain

satellite. So they calculate that to cover a large area off the western

coast of Australia, which is way farther south than anywhere they'd previously

looked.

This means that MH370 turned south and flew for six hours into the middle of

nowhere.

Some theorists say that it's not on autopilot. And why fly around for so

you intend to kill yourself? So if the plane isn't flying itself, and the

are not committing suicide, that leaves one other option.

A passenger took control of the aircraft.

There are 227 passengers on board. Any of them could be responsible.

In the world post -September 11th, we look very carefully at who's on a plane.

As they dig deeper, investigators realize not all of the passengers are

claim to be.

So they checked everybody's info, and then there was this red flag.

Two people had boarded.

using stolen passports, one Italian and one Australian.

When these two guys checked in, for some reason, the passports were not

discovered by Interpol.

So we have two men on board this airplane that are trying to hide

clearly, and we didn't know about it. We don't know who they are, fake names,

fake passports.

These guys could be anybody.

So fortunately,

It's not 1950.

It's 2014.

And there's a large number of surveillance everywhere.

We can trace these guys' steps.

The police found out these are two friends using stolen passports. Turns

these two passports were stolen in Thailand about two years before.

They bought a one -way ticket through a payphone in Thailand.

From Thailand, they entered Malaysia using their real passport.

So now we know who they are.

The men have a valid reason to hide their identities.

These are two Iranian refugees, 19 and 29, seeking asylum in Beijing.

They don't have any knowledge about airplanes.

So with those maneuvers that MH370 went through, whoever was doing it knew what

they were doing in that cockpit. So it turns out these guys were not really

suspects.

Investigators also believe...

The culprit knows how to work the plane's internal systems, like the

transponder. There's a passenger on board who might fit the bill. He's a

engineer from Switzerland.

The Boeing 777 -200 has access to the avionics bay, which is under the

cockpit.

That's in the forward first -class cabin.

And it's a small loft to get there.

This is where the flight computers are. This is where the pressurization and

everything is.

So if you could get access to this room, you could cause serious harm to an

aircraft in flight.

Would a flight engineer know about this?

Possibly.

But does the flight engineer have a motive?

When we look into this person, we find that he has a clean background.

He works on completely different type of aircraft. He works on corporate jets.

he's probably not a suspect.

With no evidence to implicate any passenger, the search goes cold for

years. Remember that proving what happened is all about the evidence, and

is none until suddenly something washes up.

It's 2017.

There's been almost no lead from MH370.

But one day, somebody's walking on the beach and makes an incredible discovery.

Over 6 ,500 miles from the Malaysian airport, wreckage appears on several

islands.

So now we finally have some hard evidence that we could look at that were

pieces of that airplane.

For three years after Malaysia Flight 370 disappears, there's no sign of the

actual aircraft.

Until 2017.

when debris begins to surface.

So now we're getting some of these chunks that are washed ashore over the

coast of Africa, Mozambique, and Reunion Island.

In all, 33 pieces are found in six different countries.

They even found this big piece. It's a flaperon unique to the 777.

That had a serial number on it that matches MH370, so it's got to be from

airplane. The parts also hold an important clue.

There was some scorch marks on the debris, and that tells me that there may

been a fire.

What we know for sure is that the transponder went off 38 minutes into the

flight. Maybe.

It is caused by the fire on board.

Fires happen for a variety of reasons, electrical, mechanical, maybe something

in the cargo hold or something in the cabin.

MH370 was carrying about 500 pounds of lithium ion batteries in the forward

cargo hold.

And we know this is more than enough to possibly bring down an aircraft, as has

happened before.

On September 3rd, 2010, UPS Flight 6 takes off from Dubai International

This was a massive 747 -400 freighter, UPS, piloted by Captain Lampe

and First Officer Matthew Bell.

138 miles into that flight, the cockpit fills with smoke.

At this point, it's chaos.

It's not smoke like from a campfire. This is thick smoke.

So thick you can't see through it.

They had no chance.

First Officer Lampe disconnected the autopilot, perhaps trying to make a

turn towards Dubai.

And when he did that, he realized the primary flight control system had failed

because of the fire, and now he couldn't quite fly it properly. The captain got

out of his seat to get a...

fire extinguisher, unfortunately succumbed by the fumes and smoke and

immediately.

Bell couldn't see his instruments, but he was given a heading towards Dubai

Airport, runway 12 left.

Sadly, he crashes a few miles on the other side of the runway.

Both pilots were killed.

The subsequent investigation

discovered that there was a pallet with 81 ,000 lithium -ion batteries on board

that freighter.

Lithium -ion batteries are extremely volatile.

Even the ones that you have in your phone, they have a high amount of charge

them, but very thin walls.

Because of the thin walls on these batteries, if one of them catches fire,

very easy to propagate.

into the other batteries adjacent to it. In rare cases, lithium ion batteries

actually combust in almost like a mini explosion.

The FAA has recorded 340 airplane incidents involving lithium batteries.

In 2019, regulations were put in place to safeguard passenger planes.

It is now prohibited to carry lithium -ion batteries in passenger airliners

in the cargo compartment of an airliner, and a very limited amount on

freighters. But that was years after pieces of MH370 began to wash up on

shores. So in the case of MH370, you have some charred wreckage. You also

a large amount of fuel in the form of lithium batteries on board.

What about the unusual flight path and erratic maneuvers?

A lot of people are questioning that sharp left turn. That could also be

explained by the fire.

We're trained that in case of a fire, what you do is you immediately get off

airway. And at first, that's what it appears that MH370 does.

Your next step is to find an airport to land.

Some of these sporadic turns could be possibly trying to figure out where are

they going to land this airplane as soon as possible.

You have to either put out this fire or get that airplane on the ground as fast

as you can.

Usually, they say it's between 12 to 14 minutes to get that airplane from

altitude down to the ground.

to basically glide, it is very hard to get it on the ground that quickly,

if you literally nosedive.

People always ask why there was no Mayday call, why they didn't call on a

Well, first of all, the aircraft may not have been capable at that point of

calling for help. The radios or the communication systems could have been

knocked out.

Additionally, you need to understand what it's like to fly in a cockpit or a

cabin that is full of dense smoke.

If your car is on fire or your truck or your boat, you can step out and jump

out. Unfortunately, you can't do that out of an aircraft.

There's no help.

Fire department is not coming.

The crew is on their own, so what they would be doing is working to put out the

fire.

777 has a very sophisticated onboard fire detection and fire suppression

But unfortunately, it was not designed to fight a lithium ion battery.

So when there's nothing else to do, the other choice is to climb the aircraft

and starve the fire of the oxygen. But the problem with that is the fire

needs oxygen to breathe.

And so do the folks in the back.

It's a gamble.

Would the fire run out of oxygen first or the people? If you don't climb,

everyone is going to burn alive.

It's very possible that everybody was dead long before it crashed into the

water. And perhaps that was the autopilot flying the airplane, and no

control until eventually he runs out of fuel.

But this evidence doesn't close the case on Malaysia Flight 370.

We have only a few pieces of this airplane that weighs almost a million

So we can make educated guesses.

We can keep digging. We can make assumptions. But the truth is we don't

answer.

In fact, some experts are highly skeptical about this physical evidence.

Some people look at patterns.

and the incredible amount of time that passed before the wreckage washed up.

And they wonder, could this evidence have been planted?

On January 17, 2017, the official search for Malaysia Flight

370 is suspended.

Despite a sweep of 46 ,000 square miles of the Indian Ocean seabed, the rest of

the plane isn't found.

So the official search, which took hundreds of millions of dollars and

to conduct, came up empty.

According to some theorists, the search might have been in the wrong area.

The officials and most of the media convinced themselves that the satellite

could only mean one thing, that the plane went south.

But they were wrong. There's another possible interpretation of the data.

The reason that search officials thought that the plane must have gone to the

southern Indian Ocean was because of satellite metadata.

MH370 remained visible to ground -based radar systems until about 2 .30 in the

morning.

After that, until 8 .19 in the morning, the only clues are the satellite data

pings.

They're able to calculate the distance of the plane from the satellite using

these pings.

and how it travels through time and space.

The time delay between the satellite sending its signal and the plane

allows you to calculate how far away the plane is from the satellite.

But that only tells you one part of the story.

The problem with those pings is it's really challenging to identify where the

airplane exactly flew.

In fact, at the time of the crash, we didn't have the technology to fully

analyze the data that was provided by MRSAT.

And then we have an airplane that's on the move. We don't know how fast it's

going, and we don't know how high it is.

These calculations have to be within milliseconds, or you could be off

of miles.

Once they did their calculation, they came to the conclusion that this data

meant unequivocally that the plane could only have gone to the southern Indian

Ocean.

But there's another possible route.

It's taken years to figure out the math here, but the data also aligns with a

northern arc.

Following the northern arc, the aircraft would have passed through northern

Thailand and then Central Asia.

If the plane did fly along the northern route, the final ping puts it over

central Kazakhstan.

If MH370 went to Kazakhstan, it opens up a frightening possibility.

This theory says that terrorists hijack the aircraft, take it to Kazakhstan,

kill the passengers, and then they could have refueled and continued to anywhere

within Russia.

If the plane went north, it could have landed safely.

It takes a lot of runway to land a big plane like the 777, and there aren't a

lot of long runways in the remote central part of Kazakhstan.

But it turns out that there is a runway not too far away that is a suitable

runway for a 777 to land on.

The place is called Yubilany Runway, and it's part of the former Soviet military

base. The big question is, did anyone on the plane have ties to Russia?

In first class, there's a Russian national named Nikolai Brodsky, and he's

sitting about 15 feet from an unlocked hatch.

which contains the electronic brain that controls all of the flight surfaces of

the plane and all the communications with the ground. And in economy class,

have two Soviet Army veterans sitting directly under the box that makes the

satellite thing.

It's entirely possible that somebody took control of the plane, killed

on board, flew off into perfect safety, refueled, went and hid the plane

somewhere.

and got away scot -free.

But if MH370 didn't crash, where did the debris come from?

Some theorists say pieces were taken off the aircraft, thrown into the Indian

Ocean to throw up investigators.

The idea that these pieces might have been planted by perpetrators would

why no debris was spotted from the aerial searches over the area where the

was presumed to be missing for months.

Was MH370 an accident or was it a crime?

Perfect.

Despite the end of the official investigation in 2018, there remain

private citizens.

dedicated to solving this mystery.

Around the world, scientists, journalists, non -profits, even major

continue to hunt for answers about what really happened to Malaysia Flight 370,

answers that will hopefully bring closure to the families of those on
