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.

SEOUL: South Korean authorities said on Wednesday (Jan 22) they will change the concrete barriers used for navigation at some airports across the country after the Jeju Air cra

The nation’s transport ministry reviewed structures near airport runways after the deadly crash of a Jeju Air flight late last month.

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.

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.

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,
