All but two of the 181 people aboard a plane that veered off a runway and hit a wall at an airport in South Korea are presumed to have died, fire authorities have said, according to Yonhap news agency. If confirmed, it would make it South Korea’s worst domestic civil aviation disaster. Footage of the incident showed the Boeing 737-800 skid along the runway at Muan international airport on Sunday morning before striking what appeared to be a concrete barrier at high speed and bursting into flames as parts of the fuselage flew into the air.
