A United Airlines flight bound for Newark declared an emergency and returned to Heathrow on Thursday afternoon (15 October) after developing a technical fault shortly after takeoff, landing safely roughly two hours later with no reported injuries.
Flight UA941 departed Heathrow's runway 27L just after 4pm, climbing to 32,000ft over Manchester before the crew declared an emergency and requested to turn back, according to aviation tracking site AIRLIVE, which followed the flight live. The aircraft, a 23-year-old Boeing 767-300ER registered N686UA, had been scheduled for an eight-hour 20-minute journey to Newark Liberty International Airport.
Pilots initially planned to dump around 20 tonnes of fuel to reduce the aircraft's weight for landing, but decided against it and returned directly to Heathrow instead, AIRLIVE reported. The aircraft touched down on runway 27R shortly before 6pm and was met by airport fire and rescue crews on the taxiway, a standard precaution for an emergency return. Landings were briefly switched to the other runway while the aircraft was inspected, before 27R reopened around 18:05 BST.
Aviation data provider AirNav Radar reported an "acrid burning smell" on board, according to London Streets, though this had not been confirmed and United Airlines had not stated the cause of the fault at the time of writing. The Mirror also reported the aircraft had declared an emergency while cruising over Manchester following a "technical issue."
United said it was preparing a replacement flight for affected passengers, due to depart roughly three hours after the original departure. Heathrow's wider operation was not affected and continued running normally throughout.
It is the second time in ten days that a transatlantic flight has turned back to Heathrow. On 5 October, British Airways flight BA295 to Chicago squawked the emergency code 7700 and circled over the Bristol Channel for several hours to burn off fuel, after oxygen masks were deployed during a rapid descent over Ireland. The aircraft landed safely and no one was injured in either incident.
Emergency returns, while alarming to witness, are a standard safety procedure. Crews are trained to treat any report of smoke, fumes or technical faults as a precaution, turning back to the departure airport rather than continuing across the Atlantic. Serious incidents can also be examined separately by the Air Accidents Investigation Branch.
What this means for your journey: these incidents did not disrupt Heathrow's wider schedule, so if you are flying with United or another transatlantic carrier, check your own flight status directly with your airline rather than assuming wider delays. Anyone collecting a rebooked passenger or adjusting a pickup time should check Heathrow's parking and drop-off options at https://heathrowairportguide.pages.dev/parking/ before heading to the terminal.
