A British Airways Boeing 777 on a transatlantic route to Chicago declared an emergency on October 5, 2026, after dropping roughly 27,000 feet in altitude. The aircraft turned back and returned to London safely. Cabin depressurization was reported as the cause.
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 reported by multiple outlets including Sky News, CBS News, and The Guardian.
