Overview
- A transatlantic flight from London to Chicago turned back after the crew declared an emergency and the jet dropped from about 37,000 feet to roughly 9,000 feet during cruise.
- Oxygen masks deployed and passengers reported panic as the crew conducted an emergency descent before diverting the aircraft to London Heathrow, where it landed safely.
- British Airways identified a "technical problem" as the reason for the turnaround and rebooked affected passengers, while the airline has not confirmed any injuries.
- Reporting and flight-data trackers identify the aircraft as a Boeing 777-200ER, registration G-VIIA, about 30 years old, a detail that investigators will examine but that does not by itself show a cause.
- A formal probe by aviation authorities and an internal airline review are expected to determine whether cabin pressurization, oxygen systems, engines, or other systems failed and to recommend safety follow-ups.
