A US company has resumed searching for missing flight MH370

The Malaysian Airlines Flight 370 disappeared March 8, 2014 with 227 passengers and 12 crew members aboard.

Malaysia's government announced on Saturday that it had given the go ahead to a private company to attempt to find the wreckage of Malaysia Airlines Flight 370, nearly four years after its baffling disappearance. The Texan company, Ocean Infinity, has just this week dispatched a fresh search vessel in the southern Indian Ocean to search for the plane's debris. The flight, which disappeared four years ago this March, was scheduled to travel from Kuala Lumper to Beijing when it made a mysterious turn off course, and eventually disappearing.

The ongoing search for MH370 was called off by the governments of Malaysia, China and Australia after nearly three years in January 2016. The Australian Transport Safety Bureau's final report on the search revealed that authorities were no closer to knowing the reasons of the plane's disappearance, or its exact location.

Conspiracy theorists have speculated several theories for the Boeing 777's disappearance – hijacking, it was switched with another flight, shot down over Ukraine, it landed on a British-owned island in the Indian Ocean or simply a planned suicide and revenge attack – but no one can be sure just yet.

The initial search for the plane played out over 52 days, where the surface searched covered an area of several million square miles in the Indian Ocean west of Australia, before an underwater search mapped 274,000 square miles of seabed at depths of up to 20,000 feet.

According to the Australian Transport Safety Bureau, these were the largest aviation searches of their kind in history.
