Divers have been finding bodies of passengers still strapped into their seats amid debris on the seafloor from the Lion Air jet that crashed Monday, an official of the Indonesian search and rescue team said Thursday.
The 2-month-old Boeing 737 Max 8 plane crashed into the sea northeast of Jakarta on Monday just minutes after takeoff, killing all 189 people on board.
Of the 189 passengers, no survivors were found, according to The Associated Press.
Indonesia's Transport Ministry said the Boeing 737-800 plane, which took off from Jakarta about 6.20 a.m., crashed just 13 minutes later.
Lion Air, a low-priced carrier, was barred from flying in US or European Union airspace due to its poor safety record.
Search and Rescue Agency chief Muhammad Syaugi said search teams are going "all out" to locate the aircraft's fuselage.
Once retrieved, it could take up to three weeks to download their data and up to six months to analyze it, said Soerjanto Tjahjono, head of the National Transport Safety Committee (KNKT).
Black boxes are mandatory on all aircraft and record both flight data from the plane and audio in aeroplane cockpits.
She said at least another 10 minutes elapsed before the flight taxied and during the flight the engine still sounded unusual to her.
But the desperate search for the recording devices has been roundly hampered by strong sea currents.
Not long after take-off, the flight's pilot requested to return to Jakarta, but communications were soon lost.
The crash is the first one involving the Boeing 737 MAX 8, a new fuel-efficient version of the legendary passenger jet.
Although pieces of the plane, passengers' personal belongings and at least six bodies have now been recovered from the seas to the north of Java island, it remains unclear about the circumstances surrounding the flight's crash.
Meanwhile Lion Air has sacked its technical director.
On Monday, Lion Air chief Edward Sirait acknowledged the plane had an unspecified technical issue fixed in Bali before it was flown back to Jakarta, calling it "normal procedure".
Indonesian airlines were barred in 2007 from flying to Europe because of safety concerns, though several were allowed to resume services in the following decade. The Federal Aviation Administration lifted that ban in August 2016.
Speaking to CNN by phone Tuesday, transportation ministry official Captain Avirianto said Lion Air now has 11 of the models in its fleet while national carrier Garuda Indonesia has one.
Local airline traffic more than tripled between 2005 and 2017 to 97 million people, according to the CAPA Center for Aviation, and is dominated by flag carrier PT Garuda Indonesia and Lion Air Group.
