Mystery remains about whether we'll ever know what happened to Malaysian Airlines flight MH370, which vanished en route to Beijing with more than 230 passengers and crew onboard 10 years ago.
It remains one of the world's most captivating aviation mysteries.
Australian officials were convinced the Boeing 777 went down in the southern Indian Ocean and searched over 120,000 square km of water to no avail.
The plane disappeared on March 8, 2014. It wasn't until July 30, 2015 that pieces of debris started to wash up on the French island of Réunion in the Indian Ocean and later in Tanzania.
But the wreckage itself has never been found.
Marine security expert, then-Australian Naval current operations manager, Jennifer Parker oversaw the search a decade ago.
On Friday, Parker told AM due to the large area the plane could've gone missing and the weather at the time, it's not surprising they couldn't find the debris field.
"That might seem strange to the listeners, those watching, but you just had no idea where it could have gone down," she said.
"The Indian Ocean is a vast area... it's a deep area and there isn't actually a lot of data in terms of the last location of the plane before it went down."
Parker described the challenges of the search, in which over 19 ships from five counties took part, including weather, visibility and not knowing exactly where currents could have pushed the plane.
The search went on for years.
Between 2014 and 2017, an underwater search took place, before company Ocean Infinity tried to do it in 2018.
"But the challenge again with the Indian Ocean is it's incredibly deep," Parker said.
"There's areas of the Indian Ocean that are not chartered at all so it's really, I hate to use the analogy, but it's that needle in a haystack analogy in terms of the size of the area and the depth of the water. It's going to be difficult to find."
Parker said it was "a really significant and sad day as we reflect on 10 years since the loss of 239 lives on MH370, including Australian and New Zealand lives".
A sad reality is that "unfortunately no" we're not any closer to finding answers on what happened that day.
"As the Malaysian Government has said, without any further information coming out that could reduce down that search area and when you look at the nature of the water in the southern Indian Ocean and the depth, I think it would be heavily challenging," Parker said.
"I do hope for the families of those lost that it is [found] but I'm not confident that it would be."
