The latest search for Malaysia Airlines flight MH370 comes to an end today, more than four years after the plane disappeared and triggered one of the world's greatest aviation mysteries.
The passenger plane disappeared on 8 March, 2014 while flying to Beijing from Kuala Lumpur with 239 people on board, most of them Chinese.
A private US firm, Ocean Infinity, has been searching for the missing airliner since January on a "no find, no fee" basis.
No sign of the Boeing 777 was found in the original 120,000sq/km Australian-led hunt, which was the largest in aviation history, and was suspended in January 2017.
Although the underwater search turned up nothing, pieces of debris from the plane were washed up on islands in the Indian Ocean and on the African coast.
