8th March 2025 – (Harbin) A China Eastern Airlines flight from Harbin to Seoul was forced to return shortly after takeoff on 4th March due to a reported medical emergency involving the pilot. According to multiple media sources, the captain experienced “in-flight incapacitation,” prompting the aircraft to issue a “Mayday” distress signal. Eyewitness accounts suggested that the pilot was foaming at the mouth and experiencing convulsions, leading Harbin airport’s command centre to activate a Level 3 emergency response. However, the airline has yet to confirm these details.
The flight, designated MU9845 and operated by an Airbus A321, took off at 5.09pm but was forced to land back in Harbin shortly after 5.46pm when the co-pilot alerted air traffic control to the situation. Emergency medical personnel boarded the aircraft upon landing and discovered the pilot in a concerning state. Although the flight was scheduled to arrive in Incheon by 8pm, it was delayed due to the incident and eventually resumed its journey around 9pm, reaching its destination shortly before midnight.
In the aviation industry, “in-flight incapacitation” refers to a pilot becoming unable to perform their duties due to sudden health issues, such as a medical condition or psychological problem. While instances of such emergencies are rare, they underscore the importance of rigorous health checks and cockpit protocols to ensure the safety of both passengers and crew. As passengers expressed their concerns online about the risky situation, speculation arose regarding the pilot’s condition, with suggestions of a seizure, although these claims remain unverified.
