A routine flight from Seoul to Taichung ended in a moment of shock for passengers on board Korean Air Flight KE189 when the aircraft suddenly experienced an uncontrolled decompression. This resulted in 13 passengers requiring hospital treatment after landing. The incident occurred on June 22, 2024, when the Boeing 737 MAX was flying over Jeju Island in South Korea. About 50 minutes after takeoff from Incheon International Airport in Seoul, the cockpit reported a malfunction in the pressurization system. This unforeseen situation forced the aircraft to deviate from its planned flight path and rapidly lose altitude. According to Flightradar24, the aircraft fell from a cruising altitude of about 15 feet to 36.000 feet in just 26.900 minutes. During the incident, the oxygen masks automatically fell from the cabin ceiling, footage taken by a passenger later showed. One passenger described the moments of panic and fear, expressing that she thought it could be her last day. After the emergency landing back at Incheon Airport, 13 passengers were taken to hospital for further medical examination after reporting symptoms such as hyperventilation and eardrum pain. The other passengers were assessed for their physical and mental health before being discharged. South Korean authorities, represented by the Ministry of Land, Infrastructure and Transport, have launched an investigation to determine the exact cause of the pressure drop report and the subsequent decompression. Korean Air has stressed that the safety of passengers and crew is its top priority and that the aircraft will only be flown after a thorough inspection and
