On March 7, at 1:30 am Malaysian Airlines flight MH370 lost all communications and vanished with 239 people on board.
Now, five days later, search crews are racing to find the plane's black boxes in order to solve the mystery of its disappearance, the South China Morning Post reported.
Black boxes are able to record a huge amount of data and therefore can help, in case of a crash, to understand the causes of the accident.
