What happened to Malaysia Airlines Flight 370? That has been the question for the last decade. And now, on the 10th anniversary of the plane's disappearance over the Indian Ocean, families of those who were on board may have renewed hope for answers. Cnn's Anna Korn has a story.

Somewhere in the depths of this vast, seemingly endless Indian Ocean is believed to be the resting place for the 239 souls on board MH370. The annoying airline that vanished a decade ago. Multiple searches spanning hundreds of thousands of square kilometers found nothing. Dozens of pieces of floating and washed up debris, the only evidence of the 777. For the families and loved ones of those who made that fateful flight on the eighth of March, 2014, from Kuala Lumpur to Beijing, it has been an agonizing 10 years. At a memorial in Malaysia, time has not eased their anguish and pain.

Families need closure. The world needs closure, and somebody needs to be held accountable.

Sarah Bajack hasn't spoken to the media for many years. It's so lovely to meet you. Her partner, Philip, was on board MH370, and the search for answers consumed her life, as it did for so many others who shared in the collective anger, frustration, and grief.

Waking up in the middle of the and expecting him to be there. That still happened for a while. And maybe that's because of a lack of closure.

She believes closure only comes once MH370 is found, and there is now renewed pressure from the families and a verbal commitment by the Malaysian government to reactivate the search.

This is the biggest mystery of the aviation in the whole world, and we must solve this mystery. It is a commitment and a promise that the search will go on.

Malaysia has agreed to speak to Ocean Infinity, the US Marine Robotics Company that ended its last search in 2018. But world-renowned aviation expert Richard Godfrey believes they'd be looking in the wrong place again. Arms with new information from the latest technology, he believes he knows the coordinates of the crash site and the area they need to search, 1,500 kilometers off the Coast Perth.

I think it will only take one more search. Search technology has improved. The crash location has been more narrowly defined. It will take them, I think, just a few weeks to find MH317.

A bold statement yet one families clings to. Zhang Wei, who lost his mother on MH370, has taken Malaysia Airlines to court on behalf of the Chinese family. That represent nearly two-thirds of the victims. He says he knows his hard-working mother, who instilled the same ethos in him, is driving her son to find the truth. I can find her shadow in me, he says. Whatever I am doing now is what my mother wants me to do. As for Sarah, the trauma has forced her to rebuild her life, running an ecotourism resort in Panama with her new husband. But she says on this day, her thoughts are always with Philip.

I make my coffee exactly like Philip used to drink it. And I sit and I think about him and maybe look at some pictures, and then I put it away. I don't think that you can effectively walk forward. You can't walk forward with positivity and confidence if you're always looking backwards.
