British Airways flight drops 9,000ft mid-air and makes emergency U-turn
BA flight drops 9,000ft in emergency U-turn over Ireland

British Airways flight BA295 from London Heathrow to Chicago was forced to abandon its journey after declaring an emergency and making a dramatic descent over Ireland.

The Boeing 777-200ER, registered as G-VIIA, departed from Heathrow's Terminal 5 at 11:50am for a scheduled eight-and-a-half-hour flight to Chicago O'Hare. Around an hour into the flight, having reached a cruising altitude of 37,000 feet, the aircraft experienced an unexpected operational problem.

Rapid descent and U-turn

Flight-tracking data shows the aircraft descending rapidly from its cruising height to approximately 9,000 feet while over Irish airspace, forcing the crew to execute a U-turn.

The emergency code used does not reveal the nature of the incident. Such emergencies can stem from mechanical failures, onboard safety threats, medical emergencies, or unclear or escalating situations, according to Dublin Live.

Diversion back to Heathrow

The code prompts air traffic control to clear airspace and alert emergency services on the ground, allowing the aircraft to land at the nearest suitable runway. Flight-tracking information indicates the plane was redirected back to Heathrow, though Flightradar24 maps show the aircraft over Cornwall.

British Airways has not yet officially confirmed the cause of the emergency.
