A Boeing 737 MAX 8, departing from Seoul's Incheon International Airport en route to Taichung, Taiwan, had to perform an emergency landing on June 22 due to a malfunctioning cabin pressurization system. The sudden descent from 30,000 feet to 9,000 feet caused ear pain, hyperventilation, and nosebleeds among passengers. Two individuals suffered nosebleeds, while 15 reported ear discomfort and hyperventilation.

One passenger likened the experience to intense rollercoaster G-forces. Thirteen passengers received medical attention upon landing, but authorities confirmed no serious injuries. This incident mirrors a similar one last October involving an Air Canada 737 MAX 8 from Mexico City to Toronto, which diverted to Houston.

A plane was forced to make an emergency landing due to a malfunction of the cabin pressurisation system - which lead to passengers suffering from nosebleeds.

The Boeing 737 MAX 8 had taken off from the Incheon International Airport in Seoul, South Korea, bound for Taichung, Taiwan when the incident unfolded on June 22.

Flight records show the aircraft suddenly descended from over 30,000ft to around 9,000ft, causing ear pain, hyperventilation, and nosebleeds for some onboard.

At least two passengers experienced nosebleeds, and 15 others reported ear pain and hyperventilation. One passenger likened the experience to the intense G-forces of a rollercoaster. A total of 13 passengers received medical attention after landing, but according to South Korean authorities, there were no serious injuries.

This incident is similar to one that occurred last October, where an Air Canada Boeing 737 MAX 8 flying from Mexico City to Toronto experienced a similar cabin pressure issue and diverted to Houston.
