Rapid Plunge: Boeing 737 drops 26,000 feet in altitude
Japan Airlines Flight Experiences Emergency Descent Due to Pressurization Malfunction
On Monday, June 30, 2025, a Japan Airlines flight (JL8696/IJ004) bound for Tokyo experienced a sudden emergency. The Boeing 737-800 aircraft, operating as a codeshare between Japan Airlines and Spring Japan, was initially bound for Tokyo Narita from Shanghai Pudong Airport.
The flight departed from Shanghai Pudong Airport without incident, but around 6:53 p.m. local time, an alert indicating an abnormality in the aircraft's pressurization system was triggered, prompting the pilots to declare an emergency. The aircraft's alarm system detected a malfunction in the mechanism responsible for maintaining cabin pressure, leading to the deployment of oxygen masks in the cabin as a precautionary measure, although a rapid decompression was officially ruled out by Japan Airlines.
The malfunction caused the plane to rapidly descend from approximately 36,000 feet to just under 10,500 feet in under ten minutes as a safety precaution. Footage shared by Newsflare captured the chaos inside the cabin during the emergency. Passengers described the experience as terrifying and life-threatening due to the sudden and steep descent.
Despite the harrowing situation, no injuries were reported during the incident. The flight was diverted to Kansai International Airport in Osaka due to the emergency and landed safely at approximately 8:50 p.m. local time.
AirlineRatings CEO Sharon Petersen commented that the pilots maintained full command of the aircraft and followed all safety protocols precisely. The incident was reported by multiple news sources including Kyodo News, The Standard, South China Morning Post, Associated Press, and people.com.
In summary, the cause of the emergency was a malfunction in the cabin pressurization system, which triggered an abnormal cabin altitude alert. The effect was an emergency descent from cruising altitude to a lower altitude. The response included the deployment of oxygen masks and an emergency landing at Kansai Airport. The outcome was no reported injuries, but passengers experienced significant stress and panic. The flight carried 191 passengers and crew.

The emergency descent due to the pressurization malfunction was a topic of discussion in airline news as well.
