South Korea's transport minister said on Tuesday he intends to step down to take responsibility for the deadly crash of a Boeing jet operated by Jeju Air on Dec. 29.

The damaged flight data recorder from the Jeju Air passenger jet that crash-landed in South Korea will be sent to the United States for analysis, Seoul’s transport ministry said Wednesday, as bereaved families began visiting the crash site.

South Korean investigators said Friday they expected to find more human remains as they began lifting the wreckage of the Jeju Air jet that crashed on landing last weekend killing all but two of the 181 passengers and crew aboard.

South Korea plans to review the concrete walls positioned just beyond the end of some airport runways after an aircraft attempting an emergency landing smashed into one just over a week ago, killing almost everyone on board.

After overcoming pariah status at the end of the last century, South Korea must learn what caused the catastrophe on Dec. 29 and what lessons to draw from it.

South Korea's government said on Monday it will extend the shutdown of Muan International Airport by a week to Jan. 14, citing the ongoing investigation into the crash of a Jeju Air jet that killed 179 passengers on board.

South Korea’s transport minister is resigning because he feels “heavy responsibility” for the Jeju Air crash that killed 179 people last month. A Jeju Air aircraft carrying 181 passengers and crew crashed at the Muan international airport on 29 December in what was the country’s worst air disaster.
