On Saturday afternoon, the Sriwijaya Air flight went missing en route from Jakarta to Pontianak on the island of Borneo. The Boeing 737-524 aircraft disappeared from radar shortly after take-off from the Soekarno-Hatta International Airport. The airplane reportedly plunged into a steep dive and then crashed into waters off Jakarta.
According to reports, the passenger plane carried 62 people on board, including 12 crew.
Early this week, the joint team retrieved the flight data recorder (FDR) of the airplane from Java Sea and subsequently handed over the first part of the black box to the National Transportation Safety Committee (KNKT).
