South Korea will remove a concrete structure at an airport runway that may have been involved in a devastating plane crash that killed all but two of the 181 people on board last month. The Boeing 737-800 skidded off the airport's runaway on Dec.

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.

South Korea will remove concrete embankments near airport runways in response to a recent air disaster, media reports said Thursday. The embankments contain antennas called localizers designed to guide aircraft during landings and have been blamed for making last month’s crash of a Jeju Air plane worse.

Seven airports will also have their runway safety areas adapted following a review of all South Korea's airports that was carried out after the crash - the deadliest in the country's history. 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.
