The disappearance of Malaysia Airlines flight MH370 in 2014, with 239 people on board, remains one of the greatest mysteries in aviation history. The Boeing 777, en route from Kuala Lumpur to Beijing, vanished after its last transmission at 40 minutes into the flight. Military radar showed it veering off course and flying back over Malaysia before heading south into the Indian Ocean. Despite extensive searches, no wreckage was found, and the mystery of its final location persists.

A multi-nation search was conducted over a 120,000 square kilometer area in the southern Indian Ocean, based on satellite data, but it ended in 2017 without results. In 2018, a private company, Ocean Infinity, conducted a further search, covering 112,000 square kilometers, but also found no traces of the aircraft. Over 30 pieces of potential aircraft debris were discovered along the coast of Africa and nearby islands, but only three confirmed pieces were from MH370.

An investigation report published in 2018 concluded that the plane's flight path was likely manipulated deliberately, but the responsible party could not be identified. Conspiracy theories about the plane’s disappearance have ranged from mechanical failure to more fantastical ideas, including alien abduction.

In a new development, Malaysia has agreed to resume the search with Ocean Infinity after receiving a proposal. The new search will cover an additional 15,000 square kilometers and is scheduled to begin between January and April, lasting up to 18 months. If the wreckage is found, the company would receive a reward of $70 million.
