A Jeju Air plane skidded off the runway at Muan International Airport, resulting in the deaths of 179 out of 181 passengers. Expert Learmount stated that the crash was caused by a concrete structure near the runway, not the landing gear. He criticized the presence of solid structures in the overrun area, suggesting that the tragedy could have been avoided. Authorities will investigate the safety of similar structures and inspect Boeing 737-800 aircraft in South Korea.
