File photo: AP</s>The search for missing Malaysian Airlines flight MH370 has expanded into a new area, after exhausting the main search zone without finding the plane.

The search for MH370 will enter its final phase this week, more than four years after it disappeared.

Searchers have so far failed to find the plane, despite exhausting a 25,000km “priority area” that had been identified by Australian experts as MH370’s most likely resting place.

The renewed search, conducted by US company Ocean Infinity, has covered 80,000 sq km of the Indian Ocean since January.

The Australian Transport Safety Bureau (ATSB) had previously searched for MH370 for three years, but the operation was called off in January 2017 after no success.

In a December 2016 report, the ATSB and Australia’s scientific research agency CSIRO announced a 25,000 sq km area north of the original ATSB search should be the next place to look.

This was based on the discovery of confirmed MH370 debris on the east African coast, which prompted new ocean current drift analysis from CSIRO.

However, on April 3, searchers finished scanning the ATSB priority area – known as Site 1 – and discovered nothing. The search ship, Seabed Constructor, continued to move north.

An April 17 report revealed the first northward extension, Site 2, had been completed with no results, and that a new extension – Site 4 – had been added to the search. Ocean Infinity has been contacted for comment on the new search zone.

On Monday, the CEO of Ocean Infinity, Oliver Plunkett said the company remained “absolutely determined” to find the plane.

“Whilst it’s disappointing there has been no sign of MH370 in the Australian Transport Safety Bureau search area and further north, there is still some search time remaining,” he said.

Under its contract with the Malaysian government, Ocean Infinity has 90 days – not including rest stops – to find the plane. The company will only be paid if it finds the plane, with the fee rising the longer the operation takes.

Seabed Constructor is in Fremantle for a scheduled refuelling stop, and will head out for the final leg of its search on Tuesday.

The search will officially end in the coming weeks when the weather in the southern Indian Ocean worsens.

Malaysia’s civil aviation chief, Azharuddin Abdul Rahman, has said the search will end in mid-June.</s>American technology company Ocean Infinity has conducted a 80,000 square kilometres scan of the area where the plane crashed is thought to have crashed, but failed to find any sign of it. The company, which previously claimed it had “a realistic prospect” of finding the aircraft, said on Monday that it had scanned up to 1,300 square kilometres per day since its mission began in late January. The search was conducted both inside and outside the 25,000-square-kilometres area previously identified by Australian authorities as most likely to contain the missing aircraft. Oliver Plunkett, chief executive officer at Texas-based Ocean Infinity, couldn’t hide his disappointment following the scan’s results.

He said: “Whilst it's disappointing there has been no sign of MH370 in the Australian Transport Safety Bureau search area and further north, there is still some search time remaining. “Everyone at Ocean Infinity remains absolutely determined for the remainder of the search.” He added that thanks to the technology used to scan the Ocean’s floor, the Ocean Infinity had gathered “significant amounts of high quality data”. The MH370 disappeared from the radars with 239 people, mostly Chinese nationals, aboard on March 8, 2014 en route from Kuala Lumpur to Beijing.

The drift patterns of few pieces of wreckage found on local beaches made authorities believe the plane crashed in the far southern Indian Ocean. The governments of Malaysia, China and Australia called off the nearly three-year official search in January 2017, but one year later the Malaysian government pledged to pay Ocean Infinity up to $70 million (£51 million) if it managed to find the wreckage or black boxes of the aircraft within 90 days. The company is using a groundbreaking technology to conduct its search. To scan the ocean it uses up to eight autonomous vehicles capable of operating in depths up to 6,000 metres.

Ocean Infinity is likely to end its operation before mid-June, as the southern hemisphere's winter could make the conditions at sea too dangerous for the search to continue. The mysterious disappearance of the aircraft led to the birth of many conspiracy theories about where the plane could be and why it went missing. The most popular one argues that the MH370 was shot down and originated from a claim made by Peter McMahon, a mechanical engineer who claimed to have found the wreckage, riddled with bullet holes, using Google Earth.</s>A new scan of the Indian Ocean scoured nearly 80,000 square kilometers but failed to find any sign of Malaysia Airlines Flight 370

But the company looking for the plane - which has been missing for more than four years - said it remains committed.

MH370 disappeared on March 8, 2014 en route from Kuala Lumpur to Beijing. There were 239 people aboard.

No transmissions were received from the aircraft after its first 38 minutes of flight, but it is believed to have crashed in the far southern Indian Ocean based on the drift patterns of crash debris that washed ashore on distant beaches.

WHY WAS THE SEARCH CALLED OFF?

The Sun reports, nearly a quarter-century after his slow-speed police chase in the SUV was televised live to captivated viewers around the world, the former grid great will land before the cameras aThe missing aircraft, which was carrying 239 passengers and crew, vanished on March 8, 2014 - with researchers saying they had been looking in the wrong place.

Despite experts never having found the body of any of its passengers, the hunt for MH370 was set to end after nearly three years.

On January 17, 2017, it was officially suspended by officials in Australia.

Only 33 pieces of wreckage were found during the hunt, which saw investigators searching the deep sea areas near to the suspected crash site in the Indian Ocean, and scanning the water from the air.

News the search teams had abandoned their mission saw a series of conspiracy theories resurface – so here are the key facts about the missing plane.

On the third anniversary of when MH370 went missing, the Australian government minister in charge of the suspended seabed search told victims’ families and friends at a church service that he remained hopeful that the plane would be found.

Darren Chester, minister for infrastructure and transport, said: “While to date we have been unsuccessful, we remain hopeful that at some stage in the future, there will be a breakthrough, the aircraft will be found, and we will be able to answer more of your questions.”

The Malaysian Government added: “We remain ever hopeful that we will be able to find the answers we seek when the credible evidence becomes available.”

On October 19, 2017, it was confirmed the Malaysian government was aiming to strike a deal with a US exploration firm to continue the search for the downed aircraft.

Proposals had been issued to Malaysia from US company Ocean Infinity, Dutch firm Fugro and a third unidentified company.

“Yes, we are negotiating with Ocean Infinity, but the agreement has not been finalised,” said Malaysia’s deputy transport minister Aziz Kaprawi.ain Thursday — this time from the Nevada prison he has called home for almost nine years after an armed-robbery conviction.

Malaysia Airlines Flight MH370 was en route to Beijing from Kuala Lumpur carrying 239 people on board.

They included Chinese calligraphers, a couple on their way home to their young sons after a long-delayed honeymoon and a construction worker who hadn’t been home in a year.

The plane had recorded 7,525 take-offs and landings as well as 53,420 flight hours when it made its last journey.

The MH370 Boeing was seen for the last time on military radar at 2.14am, close to the south of Phuket island in the Strait of Malacca.

Before that, Malaysian authorities believe the last words heard from the plane, from either the pilot or co-pilot, was “Good night Malaysian three seven zero”.

Half an hour later, the airline lost contact with the plane. It had been due to land at around 6.30am.

Evidence from a military radar suggested the plane had suddenly changed course.

Dozens of rescue planes and ships moved their search efforts to the sea west of Malaysia before the country’s Prime Minister Najib Razak claimed MH370 had been deliberately diverted by someone on board.

He added that they believed it had continued flying for more than six hours after losing contact with air control.

In the end, the search spanned to almost three million square mile - which is 1.5 per cent of the earth’s surface.

A week after disappearing satellite images of possible debris appeared to suggest that the plane crashed in the Indian Ocean, south-west of Australia.

But the search for the black box in this area was abandoned after nothing was found.

Now it seems that the search took place in the wrong location.

An international investigation revealed that the search area needs to be extended to an untouched 25,000 kilometre square area in the southern Indian Ocean.

In April 2017, a report by Australia’s national science body CSIRO supported the theory that the plane’s wreckage was north of the original search area. The report used data and analysis from ocean testing of an actual Boeing 777 flaperon.

At the end of August 2017, a diplomat investigating the doomed flight was shot dead in Madagascar’s capital in what is being called an assassination.

American adventurer-detective Blaine Gibson, who has been gathering suspected MH370 debris as it washes up on Madagascar and Mozambique, said Mr Raza had been due to deliver new items to Malaysian investigators in Kuala Lumpur.

In early 2018, conspiracy theories were sparked when the search vessel hunting for missing Malaysian Airlines flight MH370 disappeared from radar for 80 hours.

It is still unclear what caused the Seabed Constructor ship to lose its tracking on January 31.

The company, Ocean Infinity, was offered in excess of £39.5million if it found the missing plane within 90 days.

They conducted an 80,000 square kilometre scan of where the plane was thought to have crashed but did not find any trace of it on the sea bed.

On July 29, 2015 — more than a year after the plane’s disappearance — debris was found by volunteers cleaning a beach in St Andre, Reunion.

A week later investigators confirmed the debris did belong to MH370, but it did not help to locate the plane as it had drifted in the water.

On October 7, 2017, it was announced that two wing flaps found in Mauritius came from the missing flight.

Some shocked relatives found it difficult to believe that this was genuinely debris from the plane.

They said they think their loved ones are still alive and are being held at “an undisclosed location for unknown reasons”.

In August 2017, Australia released satellite imagery which it said showed 12 objects which were probably man-made floating near the suspected crash site.

The images were captured by a French military satellite two weeks after MH370 vanished, but were never released to the public.

If correct the French photographs point to an impact site in part of the Indian Ocean which was not originally searched, supporting the CSIRO April report.

WHAT HAS DEBRIS FROM MH370 REVEALED?

The wing flaps showed that the plane was not in a landing position when it plunged into the ocean, the Australian Transport Safety Bureau said.

If the pilot was planning a controlled ditching of the plane, the wing flaps would have been configured for landing.

As this was not the case, a report by the bureau concluded that the aircraft appeared to be “out of control” during its final journey.

Chief search operator Peter Foley said: “You can never be 100 per cent. We are very reluctant to express absolute certainty.

“You can draw your own conclusions as to whether that means someone was in control.”

If someone had been controlling the plane it could have glided much further than thought - meaning rescuers could have been searching the wrong area.

More than 20 bits of debris suspected or confirmed to be from MH370 have washed ashore on coastlines throughout the Indian Ocean.

However, a deep-sea sonar search for the main underwater wreckage found nothing.

WHAT ARE THE THEORIES ABOUT MH370?

Russian president Vladimir Putin was accused of being involved in the hijacking of MH370. by a US Science writer. Jeff Wise claimed Putin “spoofed” the plane’s navigation data so it could fly unnoticed into Baikonur Cosmodrome so he could “hurt the West”.

French ex-airline director Marc Dugain accused the US military of shooting down the plane because they feared it had been hijacked. A book called Flight MH370 – The Mystery also suggested that it had been shot down accidentally by US-Thai joint jet fighters during a military exercise and covered it up.

Malaysia police chief Tan Sri Khalid Abu Bakar suggested that the crash could have been suicide. He said that someone on-board could have taken out a large life insurance package before getting on the plane, so they could treat their family or pay back the money they owed.

Historian and writer Norman Davies suggested MH370 could have been remotely hacked and flown to a secret location as a result of sensitive material being carried aboard the jet.

Twitter users claim a terrifying voicemail sent to their phones could have links to missing Malaysia Airlines flight MH370, alien life and an impending Doomsday date.The creepy message features a robotic voice droning out to an automated message in NATO phonetic alphabet.

Australian amateur crash investigator Peter McMahon has claimed images from Google Earth show what he believes is the wreckage of the Malaysia Airlines plane.

He says it is located under the surface ten miles south of small islet Round Island - an area not included in the search operation by experts.

Images have emerged showing what could be the wreckage of missing Malaysia Airlines flight MH370 and it’s covered in bullet holes, an expert has claimed.

The Google Earth pictures show what appears to be the outline of the plane, which vanished along with 239 passengers and crew, under the surface of waters just north of Mauritius.

WHAT DID THE FINAL REPORT SAY?

In October 2017, Australian investigators delivered their final report into MH370’s disappearance and the subsequent search.

The Australian Transport Safety Bureau (ATSB) - the agency which co-ordinated the search has said the fact the plane has yet to be found is a “great tragedy”.

ATSB chief commissioner Greg Hood said: “I hope, however, that they can take some solace in the fact that we did all we could do to find answers.”

The report states that while the plane has yet to be found, the hugely expensive search, the most expensive in aviation history, has managed to rule out large areas of the Indian Ocean off the western coast of Australia.

The report said: “The underwater search has eliminated most of the high probability areas yielded by reconstructing the aircraft’s flight path and the debris drift studies conducted in the past 12 months have identified the most likely area with increasing precision.
