San Francisco, Jan 16 (IANS): American airplane giant Boeing has said that its technical experts are assisting with investigation in last week's Sriwijaya Air plane crash.

"Boeing technical experts are assisting with the investigation and we continue to offer any support needed during this difficult time," the company said in a statement on Sunday.

"Our thoughts are with the Sriwijaya Air flight SJ-182 crew, passengers and their families," Xinhua news agency quoted Boeing as saying.

The Boeing 737-500 passenger aircraft with 62 people aboard slammed into the Java Sea on January 9, minutes after take-off from Jakarta en route to Indonesian city of Pontianak in West Kalimantan province.

Indonesian authorities have downloaded the flight data recorder (FDR) belonging to the crashed Boeing 737-500, the country's National Transportation Safety Committee said on Friday.

As many as 239 body bags containing human remains had been retrieved and 12 victims have been identified after forensic examinations in the police's hospital as of Thursday.

The National Transportation Safety Committee (KNKT) has retrieved data from the flight data recorder (FDR), but the search team is still looking for the aircraft's CVR.
