A United Airlines Boeing 777-200 was forced to make an emergency landing at London Heathrow Airport shortly after takeoff due to smoke detected in the cabin. Flight UA949 had departed for San Francisco at 12:23 PM.
The aircraft stopped its climb at around 15,000 feet near Milton Keynes when the crew issued a smoke alert and diverted the flight back to Heathrow. Fire and medical teams were on standby during landing, and the evacuation was carried out safely.
Same Aircraft Declared an Emergency Just a Week Ago
According to information shared by Air Live, the same aircraft had declared an emergency just seven days earlier during its approach to San Francisco due to an engine malfunction. Following that incident, United Airlines stated the aircraft required a technical reassessment.
After today’s incident, the aircraft was escorted to the gate by three fire trucks. United Airlines announced that maintenance teams would carry out a comprehensive inspection before returning the plane to service.
Heathrow Airport Operations Remained Largely Unaffected
Officials stated that the emergency landing had minimal impact on operations at Heathrow Airport. However, the incident has once again brought attention to safety and technical oversight at London’s busiest airport.
Heathrow: Record Passenger Numbers Amid Financial Decline
This event followed Heathrow Airport’s recent report of record passenger traffic and a 37.2% drop in half-year profits. From January to June 2025, the airport handled 39.9 million passengers – an all-time first-half record – while pre-tax profits fell to £203 million.
CEO Thomas Woldbye revealed that a transformer fire in March was expected to cost the airport millions in damages. Another detail that made headlines was Woldbye reportedly sleeping through the crisis with his phone on silent, leading to delayed intervention during the emergency.
