Passengers on a Japan Airlines flight experienced a harrowing incident when their Boeing 737 aircraft descended nearly 26,000 feet due to a mechanical failure. The event occurred on June 30, during a flight from Shanghai Pudong Airport to Tokyo Narita. The flight was operating under the codeshare JL8696/IJ004 between Japan Airlines and its low-cost affiliate Spring Japan.
According to reports from Kyodo News, The Standard, and South China Morning Post, the aircraft had 191 passengers and crew on board when it encountered a pressurization malfunction around 6:53 p.m. local time. This caused the plane to rapidly descend from approximately 36,000 feet to just under 10,500 feet within minutes.
The Associated Press and Japan’s Ministry of Land, Infrastructure, Transport and Tourism confirmed that oxygen masks were deployed throughout the cabin. A passenger reported hearing a “muffled boom” before the masks dropped and described how a stewardess urged everyone to put on their oxygen masks due to the malfunction.
