An early investigation by the National Transportation Safety Commission (KNKT) showed Tuesday that the flight system of a Boeing 737-500 jetliner with 62 people on board that crashed in the sea off Jakarta was functioning during the impact.

Data of Sriwijaya Air Flight 182 that had been recorded until the plane descended to 250 feet (76.3 meters) above the water's surface before the crash on Saturday have "indicated that the flight system was functioning and able to send data," according to Soerjanto Tjahjono, chief of the KNKT.
