Flight BA295 returned safely to London after a cabin-pressure problem prompted an emergency descent and the deployment of passenger oxygen masks.
LONDON, ENGLAND — A passenger aboard a British Airways flight bound for Chicago described uncertainty inside the cabin after oxygen masks dropped and the Boeing 777 rapidly descended thousands of feet over the Irish Sea before returning safely to London Heathrow Airport.
British Airways Flight BA295 was traveling from Heathrow to Chicago O’Hare International Airport on Oct. 5 when the aircraft encountered what the airline described as a technical issue. Aviation incident reports said the Boeing 777-200ER was cruising at about 36,000 feet when the crew began an emergency descent following a loss of cabin pressure. The aircraft reached about 9,000 feet roughly seven minutes later, a descent of approximately 27,000 feet.
Passenger Tom Nicholls said there was sudden turbulence before the oxygen masks deployed from the cabin ceiling. He described uncertainty among passengers as they tried to understand what was happening. Nicholls said the descent itself did not feel as severe as the flight-tracking data later showed and praised the pilots for how they handled the aircraft.
Nicholls said some passengers initially had difficulty reaching oxygen masks. He said the captain later told passengers that the aircraft had descended below 10,000 feet and the masks were no longer needed. The rapid descent brought the jet to an altitude where the immediate risks associated with a cabin-pressure problem were reduced.
The crew transmitted the 7700 emergency transponder code, which alerts air traffic controllers that an aircraft has a general emergency. Aviation reports said passenger oxygen masks were released as the aircraft descended. The jet had been flying over the Irish Sea, about 40 nautical miles south of Dublin, when the emergency descent began.
After reaching about 9,000 feet, the aircraft abandoned its planned Atlantic crossing and headed back toward Britain. Flight-tracking information showed the plane remaining airborne for several hours and flying holding patterns before returning to Heathrow. Reports indicated the extended flight allowed the aircraft to reduce its weight after beginning what was supposed to be a long transatlantic trip.
British Airways said its highly trained pilots returned to Heathrow following a technical issue and that the aircraft landed safely. The airline said passengers left the aircraft normally and staff were working to arrange their onward travel. No injuries were immediately reported, and British Airways did not disclose the number of passengers aboard the flight.
The precise technical fault that caused the pressure problem had not been publicly identified as of Tuesday. A loss of cabin pressure at cruising altitude requires crews to quickly bring an aircraft to a lower altitude because the outside air at normal jet cruising levels cannot support normal breathing without supplemental oxygen. Passenger oxygen masks provide a temporary oxygen supply during such an emergency descent.
The aircraft involved was identified in aviation reports as G-VIIA, a Boeing 777-200ER. British Airways had not announced a detailed cause of the technical failure, leaving the specific reason for the cabin-pressure problem unresolved. The flight’s safe return ended the immediate emergency, while affected passengers were being assisted with revised travel arrangements.
