The wife of MH370's captain has gone into hiding and is refusing to answer questions over her husband's state of mind two years after the jet disappeared with 239 on board.
Faizah Hanun has been questioned several times by Malaysian police and FBI investigators who have asked her about rumours she and pilot Zaharie Ahmad Shah had separated.
The 53-year-old pilot and his wife had continued to live under the same roof in Kuala Lumpur, despite the split, it is claimed.
What she has told investigators is understood to have been an important factor in the interim conclusions to be released about the airline's fate.
But she has refused to reveal intimate details about her husband's thoughts and behaviour leading up to him taking control of the doomed Boeing 777.
Shah and his wife are reported by friends to have continued living under the same roof in an upmarket part of Kuala Lumpur, despite being separated.
But whether the marriage breakdown would have led to him killing himself and all on board the jet is still unknown.
The Malaysia Airline MH370 took off from Kuala Lumpur and disappeared en-route to Beijing on March 8, 2014, two years ago today.
A new report into the disappearance released today failed to shed any new light on what may have happened to the missing jet.
In Australia, Irene Burrows - whose son Rodney and his wife Mary were on board the plane as it flew from Kuala Lumpur to Beijing - said: "I'm convinced the pilot did this terrible thing."
Speaking to MailOnline, Mrs Burrows said: "I believe he took the plane up high until the oxygen ran out, causing everyone to lose consciousness before the oxygen bags dropped down and then the auto-pilot took over and nobody knew anything when it came down."
Mrs Burrows, 86, and her 88-year-old husband George, suffered a second tragedy that year when their step-granddaughter died on MH17 after it was shot down over Europe.
"But at least we know what happened to that plane and we have been able to grieve," she said at her home in Biloela, Queensland.
"But we are only left to wonder what happened to MH370 and while our grieving for all those on that plane continues, life must go on. We had all the family here at the house at the weekend and all the photographs came out and it was a very emotional time.
"Two years ago, before we heard the news about the plane missing, we were just two ordinary people having a quiet day just like any other - and then our world was turned upside down.
"I know that everybody is doing everything they can to find out what's happened but I just hope that George and I live long enough when, or if, the answer comes in. I know it must be the same for everyone who had someone on that plane - the 'not knowing' is the worst.
"I've often wondered if she and Rodney should have followed Mary's intuition and not got on that plane.
"She told other family members that she had a bad feeling about the flight before they took off, but I don't know any more than that."
MH370 took off at 12.41am for a six-hour flight to Beijing with Captain Zaharie at the controls, assisted by co-pilot Fariq Hamid.
But as it flew over the South China Sea, heading towards the southern tip of Vietnam, it suddenly lost all contact with ground control. At Beijing airport families waiting to greet loved ones stared anxiously at the arrivals board, waiting to see the word "landed".
But it never appeared. The South China Sea was searched for signs of wreckage, before aviation and satellite experts agreed that radar and automatic electronic "handshakes" with the aircraft pointed to it turning back from its north-east course and heading across the Malaysian peninsula and in a south-easterly direction towards the southern Indian Ocean.
A detailed search using sophisticated underwater drones scouring 85,000sq km of the sea floor has to this day failed to find any clues as to where the aircraft came down, assuming it had continued flying until it ran out of fuel.
French investigators have yet to release a final report on the discovery of a flaperon - a wing part - found on the island of La Reunion, near the east coast of Africa, confirming that it is from MH370.
And the result of a detailed examination of another possible part found off the coast of Mozambique last week is also expected within days.
The metal parts have brought mixed feelings to families of the passengers, for the pieces suggest that the plane was smashed to pieces when it hit the sea - but it also takes them a step nearer to what many agree would be "closure".
"Maybe he will come back, maybe he won't," Maira Elizabeth Nari, 20, eldest daughter of MH370 chief steward Andrew Nari, said in Kuala Lumpur today. "Wherever they may be, I have never stopped praying to God to give them protection.
"Dead or alive, may God bless them all. You see us smile and laugh, but only God knows what is in our hearts and minds," she told the Bernama agency. "Your heart cries every night or at any time when you suddenly feel sad."
