This part of the Indian Ocean is only a tiny portion of the present search area - 469,407 square nautical miles of seasickness, about 2253 times bigger than the area of Singapore.

The search team is racing to find the black boxes which have battery life of up to 45 days after a crash. It is now Day 17.

Without the black boxes, it would be virtually impossible for investigators to definitively say what caused the crash.

Clarification: It has come to our attention that this video is actually a footage of the Atlantic Ocean during a hurricane season.

The Atlantic Ocean has the second deepest depth in the world (9,219 metres), and the Indian ocean comes third at 7,455 metres deep. With the rough weather conditions the MH370 Blackbox Search & Rescue team was facing, the conditions could be just as horrid as depicted in the video.

What Happened to MH370?: The Full List of Possibilities


It is known that the jet's communication and tracking systems - the transponder, and the Aircraft Communications Addressing and Reporting System or ACARS - were turned off deliberately.

This happened as the Boeing 777-200ER was leaving Malaysian airspace and entering Vietnamese territory. Shortly after, it diverted from its original flight path.

The last satellite transmission was at 8:11am on March 8 - 6½ hours after Malaysian air traffic control lost contact with the jet. Until that point, there was no distress signal from the cockpit.

No debris has been found.

What Did Not Happen

A major catastrophic mechanical failure is out. This would have caused a mid-air explosion which would have been detected.

A rapid fall in cabin pressure or in-flight fire is unlikely.

Even if there is a total engine failure at 35,000ft, a plane can continue to glide and pilots have about 15 to 20 minutes to do what they need to, such as send alerts.


So what we are left with is..
What Possibly Happened:

Botched hijack

It was a botched hijack where someone on the plane, or a pilot, took control but did not achieve his intention.

Malaysian authorities have said they did not receive any demands over MH370, but it is possible they were in negotiations with hijackers. Some questioned if the authorities or those on board could have tried talking with the hijackers, but the plane might have run out of fuel and crashed before a decision was made.

It is also possible the pilots or crew tried to stop the criminals. A fight could have broken out and the plane crashed.

Pilot suicide

Malaysia Airlines has confirmed that the co-pilot was the one who said 'All right. Goodnight', just before the transponder was deactivated.

Initial investigations showed that Fariq Abdul Hamid, 27, sounded calm at the time, suggesting he was not under any threat.

Fingers have also been pointed at Captain Zaharie Ahmad Shah, 53. Police seized a homemade flight simulator from his home which experts are analysing. They are probing whether the pilots had financial or other troubles.


'Ghost' flight

It is possible that something happened which knocked out everyone on the plane - without any criminal intent - causing it to fly of its own accord.

Experts say it could have taken less than a minute for the pilots, passengers and crew to lose consciousness during a catastrophic loss of pressure that somehow also led to a systems malfunction.

The authorities believe that after the plane lost contact with air traffic controllers, it could have climbed as high as 45,000ft - above the normal cruising altitude - which would have led to such a drastic fall in cabin pressure.

Combined theory

There is another explanation for MH370, aviation and security experts said - which contains elements of the earlier three.

It cannot be ruled out that something or someone was on the plane that was important enough for an organisation or group to stage a hostile takeover.

Hijackers could have taken the plane to 45,000ft to knock everyone out, then landed it in an unknown location. After getting what they wanted, they got the jet back in the air by remote flying and crashed it.


How fast MH370 fell and whether the aircraft broke before it plunged into the Indian Ocean or on impact, depends on which of the above theories you believe, aviation experts said. This in turn determines what sort of debris could be found and whether there might even have been survivors.

If it was pilot suicide, it is likely the plane nosedived steeply causing an impact which would have caused the aircraft to disintegrate into small pieces even before it hit the waters.

If a plane crashes because fuel runs out, it would plunge into the ocean 'within a few minutes', said Mr H.R. Mohandas, a former pilot who teaches aviation at Republic Polytechnic. Such an impact would be akin to hitting concrete and cause debris from the plane to scatter over a large area.

If there was someone flying the aircraft, the descent would have taken about 15 minutes before it hit the water, he said. While the impact could have left some survivors, they are unlikely to have survived long in the icy cold waters. 


These limited knowledge and theories could become all we know about the loss of MH370, should the black box not be found in another 11 days. The clock is ticking. However, the waters of the oceans remain treacherous. Watch the video and get a glimpse of what the search team faces everyday.
