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,

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.

South Korean authorities are still investigating the cause of the recent air disaster at Muan International Airport. Some are blaming a concrete embankment at the end of the airport runway, which will now be removed.

The South Korean government have said it will remove the concrete localizer structure that a Jeju Air Boeing 737-800 crashed into at Muan International Airport.

The Jeju Air Flight 2216 crash triggered by a bird strike and dual-engine failure, has raised pressing questions around aviation safety, wildlife management, and airport emergency preparedness. Here’s what we know so far,

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 remove hazardous structures found near runways at seven of its 14 airports across the country, following the crash of a Jeju Air flight that killed 179 of the 181 people on the plane last month,

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 airport is the site of the Dec. 29 crash of the Jeju Air Boeing 737-800 jet that killed 179 passengers on board.

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.
