10 years on, is the world any closer to finding MH370?

CNN —

For the past 10 years it has remained one of the modern era’s greatest mysteries.

A commercial airliner with a strong safety record carrying 239 people vanishing from the map, spawning a wide variety of competing theories, books and documentaries and leaving the families of those left behind asking themselves every March 8 – what happened to those aboard Malaysia Airlines flight 370?

In an era when black boxes have been successfully hauled up from the very depths of the ocean and whole chunks of a downed airliner painstakingly pieced back together to determine what caused a catastrophe, the fate of MH370 remains infuriatingly elusive.

It is a plane crash without a plane. A disaster without conclusive proof of what happened to its victims. A story that anyone who embarks on a commercial flight can instantly relate to but one that, for now at least, doesn’t have a closing chapter.

Yet many experts believe there is still a strong chance MH370’s wreckage could be located, if someone looks hard enough and – crucially – coughs up the staggering amount of money that might be required to achieve that goal.

“But we never found MH370. I never found my mother,” Jiang told CNN. “I can’t commemorate my mother just like everyone else.”

His mother, Jiang Cuiyun, is still listed as “missing” back home in China, he
