A British Airways service to Chicago returned safely to London Heathrow on Monday, 5 October, after a technical problem interrupted its journey over Ireland.

Flight BA295, operated by a Boeing 777-200ER, abandoned its planned crossing to Chicago O’Hare after making a rapid descent. AirLive reported that the aircraft descended from approximately 37,000 feet to 9,000 feet within minutes. The crew transmitted the emergency transponder code 7700, alerting air traffic controllers that assistance could be required.

Oxygen masks were deployed inside the cabin during the incident, according to reports and onboard photographs. British Airways confirmed a technical issue but did not specify the fault in its initial statement.

After turning back towards England, the aircraft circled over the Bristol Channel for several hours. It eventually landed at Heathrow shortly after 5 pm, and the airline said passengers left the aircraft normally. British Airways teams were assisting affected travelers with arrangements to continue their journeys.

The precise reason for the descent remained unconfirmed in the available reports. Although AirLive identified a cabin-pressure problem as one possible explanation, British Airways had not confirmed that the aircraft experienced depressurization.
