It's been a decade since flight MH370 vanished. Now an expert thinks we're close to the truth.

It's hard to fathom it's been a decade since the disappearance of flight MH370, families and loved ones still desperate to find answers.

The Malaysia Airlines flight disappeared from radar on March 8, 2014 on its way to Beijing from Kuala Lumpur. 

Six Australian citizens and one New Zealand resident of Western Australia were on board, a total of 227 passengers and 12 crew on the plane. Approximately 40 minutes into the flight, the plane disappeared from the radar and was never found. Its fate remains unknown. 

Many experts have assumed amid the available evidence that the plane crash was an intentional act of murder, committed by the plane's captain, Zaharie Amhad Shah. John Dawson, a lawyer who represents some of the victims' families, told News Corp the evidence pointed towards one of the crew being involved.

Former Prime Minister Tony Abbott — who was the leader of Australia at the time of the plane's disappearance — says he was told "very early on" by Malaysian officials that the pilot hijacked his own aircraft in an act of murder-suicide.

The first search was co-ordinated by Australia in 2014 and involved the Malaysian and Chinese governments before it was officially called off in early 2017.

In June 2015, a piece of debris from the plane was believed to have been found on Réunion Island, east of Madagascar. Some experts don't believe this is part of the plane. The bulk of the aircraft and its black box has not been located.

Two formal investigations failed to uncover what happened on the aircraft. The Malaysian report said there was no definitive evidence the pilot hijacked his own plane.

Amid the 10-year anniversary, the families have gathered in Malaysia and called for another search.

But interestingly, there's one journalist who thinks someone knows exactly what happened.

Are we any closer to finding out the truth of MH370?

Florence de Changy is a French journalist and the author of The Disappearing Act: The Impossible Case of MH370. She has been following the case for a decade now, and with her extensive research in mind, she has a theory or two.

What we've been told from officials is that MH370 at some stage in its journey did a u-turn, and then it supposedly ended up somewhere in the Indian ocean southwest of Australia. De Changy believes differently, alleging there has been a cover-up of sorts.

"I looked at every moment of this official narrative starting with the u-turn and that is beyond capability for this sort of Boeing plane. Even when they tried with a simulator to recreate the u-turn, they could not do it," she tells Mamamia's news podcast The Quicky.

"It's impossible. It's beyond the altitude." 

Another point of investigation for de Changy has been reports of unusual cargo aboard MH370.

"I found that there was a problem with the cargo. Some of the cargo that was delivered on the night to the plane was under escort and also wasn't scanned — this is an enormous no-no," she claims.

"You have people at the highest level of government who know. The people who know obviously have no interest whatsoever in the truth being uncovered. I don't think we will find the plane, but I do think we will find the truth. The secret for the few people who hold it is a very heavy and unpleasant secret to live with. Among the few people who know, there would be someone with a conscience. I hope they speak out."

Malaysian Prime Minister Anwar Ibrahim has said he is inclined to reopen the investigation if new evidence comes to light. American company Ocean Infinity has offered to search for the wreckage but the Malaysian Government has requested new evidence before it signs off on another operation. The company's 2018 search came up empty.

"If we have a compelling case to reopen the investigation, we will," Prime Minister Ibrahim said this week.

Maritime security expert Jennifer Parker — who oversaw the operation — told AAP the Malaysian Government is right to ask for more evidence before it searches again and gives false hope to families.

"Finding a plane at such depths was a needle in a haystack operation and the actual depths of the southern Indian Ocean remained unknown because they are uncharted," she said. 

But new technology could help a new search. If one piece is found it's likely the whole wreckage would be too and the cold and calm nature of the bottom of the ocean meant parts could still be preserved.

With the anniversary front of mind, Foreign Affairs Minister Penny Wong this week said Australia's sympathies remained with the families and loved ones.

"We recognise their ongoing heartache and grief without the answers they seek. While the searches have not been successful, and families continue to endure such heartache, the effort to find MH370 demonstrates the close co-operation between our countries through difficult times," she said.

"The Australian government is supportive of all practical efforts to find MH370."

"It's still on everyone's minds in Malaysia," de Changy tells The Quicky. "239 people perished in the southern Indian ocean. It's time to say enough of this nonsensical official narrative."
