The ill-fated Lion Air plane, with 189 people on board, en route to Depati Amir Airport in Pangkalpinang, crashed into the waters of Tanjung Karawang just 13 minutes after takeoff from Jakarta`s Soekarno-Hatta Airport at 6:20 a.m. West Indonesia Standard Time and scheduled to arrive in Pangkal Pinang at 07.10 WIB.
"We found a ping locator, there was a device in the black box, the Commander and I had heard the voice," head of the National Search and Rescue Agency (Basarnas) Head Muhammad Syaugi said at a press conference at the JICT II port in Tanjung Priok Port, Jakarta, Wednesday night.
According to an explanation, there are two different sounds of the ping locator with strong and rather weak intensities.
The rather weak ping sound came from one part of the black box which was covered in sand or seabed sediment.
After these findings, a number of reliable divers from the Taifib and Marines and a "Remote Operating Vehicle" (ROV) were also deployed to ascertain the origin of the underwater ping signal.
Therefore, his team will seek permission from Pertamina to be allowed to sell anchors so that they can carry out diving missions safely and smoothly.
Although they have not succeeded in finding the physical black box or fuselage, the team is sure that the location of their search is right because they found other physical evidence on the seabed.
In addition, a team of divers and ROV managed to find a number of objects related to the aircraft.
