A South Korean report confirmed that the Jeju Air crash, which killed 179 people, involved bird strikes from Baikal teals found in both engines. However, the cause remains undetermined as the plane's black boxes stopped recording about four minutes prior to the incident. Warning of potential bird strikes was issued just two minutes before the plane declared an emergency. Investigators are analyzing various components and safety protocols, with the Muan airport's concrete localizer structure under scrutiny, prompting plans for its removal. The investigation, in collaboration with U.S. officials, continues as authorities seek a final report within a year.
