British Airways BA295 dives 28,000 feet after suspected cabin-pressure loss, lands safely back at Heathrow

· N GLOBE

BA295 from London to Chicago on Oct. 5 dropped from ~36,000 ft to 9,000 ft in about 7 minutes after a suspected loss of cabin pressure, squawking 7700 before returning safely to Heathrow with no injuries.

Why it matters

This is textbook emergency procedure for a suspected cabin-pressure loss at cruising altitude: the crew squawked the international emergency code 7700, passenger oxygen masks deployed, and the aircraft turned back over Ireland, circled off England's west coast to burn fuel, then landed safely. Nobody was hurt, though the transatlantic service spent more than four extra hours in the air.

Full report

British Airways flight BA295, a Boeing 777-200ER (registration G-VIIA), departed London Heathrow at about 12:14 p.m. local time on Monday, Oct. 5 (roughly an hour behind schedule), bound for Chicago O'Hare. About an hour after takeoff, at a cruising altitude of roughly 36,000–37,000 feet, the crew suspected a cabin-pressure problem over Ireland — about 40 nautical miles south of Dublin — and began an emergency descent, dropping roughly 27,000–28,000 feet to 9,000 feet in about seven minutes while transmitting squawk code 7700. Oxygen masks dropped in the cabin.

The crew abandoned the transatlantic crossing and turned back toward Britain, entering a holding pattern over the Bristol Channel to burn off fuel before landing safely on Heathrow's runway 27L after about 4 hours 47 minutes airborne. Passengers disembarked normally and no injuries were reported. British Airways confirmed the return was due to a technical issue but disclosed no cause; reports of depressurization remain unconfirmed. The subsequent service was cancelled.
