Authorities in Indonesia are hoping to find the black box of the crashed AirAsia plane today, after ping signals from the device were detected.
The search team detected signals 3.5 kilometres from where the aircraft's tail was discovered.
Bambang Soelistyo is the Head of Indonesia's National Search and Rescue Agency.
"We can confirm that we have detected ping signals from the black box, but the black box has not been found yet. I repeat, the black box has not been found yet."
A team of navy divers has also found a wing and debris from the engine at the bottom of the Java Sea.
In the meantime, the tail of the ill-fated plane has been brought ashore in Indonesia.
AirAsia Flight 8501 lost contact with air traffic control during a storm less than half-way into a two-hour flight from the Indonesian city of Surabaya to Singapore.
There were no survivors among the 162 people on board.
