A British Airways Boeing 777 flying from London to Chicago declared an emergency on October 5, 2026, after losing around 27,000 feet of altitude rapidly. The aircraft diverted and landed back at London without incident. Cabin depressurization was identified as the reason for the emergency.
A passenger on board described a rapid loss of altitude and cabin pressure during the incident. The frightening experience unfolded over the Atlantic before the crew chose to turn the plane around. The flight's diversion was covered by several news organizations including Sky News, CBS News, and The Guardian.
