In 2014, as Malaysia Airlines Flight 370 was disappearing over the Indian Ocean, French scientists had coincidentally deployed underwater listening devices in the same waters. Nearly a decade later, their recordings might finally crack aviation's greatest mystery—except nobody realized they existed until now.

What happens when excitement takes over, a fake is passed off as the real deal, and someone's death gets caught up in a huge international mess? Here's the crazy story of how one phony mummy triggered a diplomatic showdown and led to the discovery of a murder victim.

Compare that to the previous record holder, which needed over a decade to cover the same distance. Pretty efficient, right?
