South Korea will remove a concrete structure at the runway of one of its southern airports, the scene of a plane crash that killed all but two of the 181 people on board last month.

Son Chang-wan was in office while works were undertaken at Muan International Airport. Last month, a plane crashed into a concrete barrier there, killing 179 people.

South Korea will tear down concrete walls at several airports, including Muan International Airport, after the Jeju Air plane crash in December.

Experts have suggested the casualty count in the air crash could have been lower had a concrete structure at Muan airport not existed

SEOUL (Reuters) - South Korea's transport ministry said on Wednesday that it would remove the concrete embankment installed at Muan International Airport following last month's Jeju Air crash, its deadliest domestic air disaster.

Son Chang-wan, a former president of the state-run Korea Airports Corporation, who spearheaded a controversial facility upgrade at Muan International Airport, was found dead at his home in Gunpo, Gyeonggi Province,

South Korea will extend runway safety areas and redesign infrastructure after the crash of a Jeju Air Co flight last month that killed almost everyone on board, sparking criticism that the design of the airport might have exacerbated the accident.

The Jeju Air flight was bringing passengers home from Thailand after Christmas when it made an emergency landing at Muan airport and exploded after slamming into a concrete barrier at the end of the runway.

South Korean authorities said on Wednesday they will change the concrete barriers used for navigation at some airports across the country after the Jeju Air crash that left 179 people dead.

The deadliest plane crash in South Korea's history is triggering a change at the country's airports. The BBC reports the concrete barriers that contain navigation systems at seven airports will be altered in the wake of the crash,
