A new search for missing flight MH370 off Perth coast

The search for missing flight MH370 is back on, more than a decade after the plane mysteriously vanished.

UK-based company Ocean Infinity has struck a "no find, no fee" deal with the Malaysian government to scan about 15,000 square kilometres of the Indian Ocean, roughly 1500km off the coast of Perth. This time, the search will be much more focused than previous efforts, which covered a massive 200,000 square kilometres.

The crew aboard Ocean Infinity’s search vessel, the Armada, will zero in on four key hotspots. But it's not going to be easy—experts say the deep-sea terrain is rough, with underwater cliffs and even volcanoes making the job extra tricky. Swells in the area are also pretty intense, thanks to Cyclone Bianca churning off the WA coast.

If wreckage is found, there's still a lot of uncertainty over what happens next—who takes charge of the recovery, how the black boxes would be analyzed, and what it all might reveal.

MH370 disappeared on March 8, 2014, with 239 people on board, including six Australians. Despite multiple searches over the years, no definitive answers have ever been found. Now, with this latest effort, families and aviation experts are hoping for a long-awaited breakthrough.
