The incident happened on June 23, 2019, during a Transasia Airways flight from Incheon in South Korea to Okinawa, Japan. According to passenger accounts, a male passenger opened the emergency exit door during the flight, causing a sudden air pressure change that caused some passengers to suffer minor injuries.
The flight was diverted and landed safely in Nagoya, Japan, where the passenger was taken into custody by the local authorities. According to reports, the man had been drinking before the flight and was acting erratically during the flight. He has since been detained while an investigation into the incident is underway.
