Investigators have finished extracting data from one of the black boxes from the fated Jeju Air plane that crashed on Sunday, South Korea's transport ministry has said.

South Korean investigators probing a Jeju Air crash which killed 179 people in the worst aviation disaster on its soil said Wednesday they will send one of the retrieved black boxes to the United States for analysis.

Hours after a Jeju Air plane crash-landed and burst into flames, killing 179 people on board in the worst aviation disaster on South Korean soil, a photo of an aircraft's burnt out fuselage was shared in social media posts that falsely claimed it showed the wreckage.
