A British Airways flight bound for Chicago declared a mid-air emergency on Monday after dropping around 28,000ft in a matter of minutes and making a dramatic U-turn over Ireland.
Flight BA295 had taken off from Heathrow Terminal 5 at around midday, with a scheduled flight time of eight hours and 40 minutes to Chicago O’Hare International Airport. About an hour into the journey, having reached its cruising altitude of 37,000ft, the Boeing 777-200ER appeared to run into trouble.
Flight-tracking data showed the aircraft descending rapidly to roughly 9,000ft over Irish airspace, according to multiple outlets including the Mirror, AOL and The Hindu. The flight crew squawked 7700, the internationally recognised transponder code that signals a general emergency to air traffic control.
The code tells controllers that an aircraft needs priority handling but does not by itself reveal what has gone wrong. Possible triggers for this kind of alert range from mechanical faults to medical emergencies or cabin pressure issues, with aviation sources noting that a rapid controlled descent below 10,000ft is often associated with a cabin depressurisation event. British Airways had not confirmed the cause as of the time of publication.
Images said to have been taken inside the cabin appear to show oxygen masks deployed and being worn by passengers, though this has not been officially verified by the airline.
Rather than returning directly, the jet – registered G-VIIA, reportedly the oldest aircraft in the BA fleet – continued as far as Cornwall before turning back, then circled over the Bristol Channel to burn off fuel ahead of landing. It changed course once more near north Wales before heading in to Heathrow, touching down safely on runway 27L at around 5pm, roughly four hours and 48 minutes after it had first departed.
What happens next
British Airways has not yet issued a public statement detailing the exact nature of the emergency, and several outlets, including The Hindu and The Mirror, say they have approached the airline and Heathrow for comment. Until an official explanation is given, the precise cause of the sudden descent remains unconfirmed.
The incident drew heavy attention from flight-tracking enthusiasts and aviation watchers as it unfolded, with “BA295” trending in UK searches. It also comes just days after a separate, unrelated emergency involving a flydubai flight from Dubai to Tel Aviv on 30 September, which triggered both the 7700 and 7500 codes following an alleged cockpit altercation and led to a terror investigation. Aviation authorities have stressed that the two incidents are entirely separate, with nothing to suggest any link between them.
For now, passengers on BA295 are back on the ground in London rather than on their way to Chicago, and will presumably be rebooked once the cause of the emergency is established. Nocturnal News will update this story as British Airways releases further information.
