Delta Air Lines Flight 30, operated by a Boeing 767-432(ER) registered N834MH, was en route from Atlanta (ATL) to London Heathrow (LHR) with 248 souls on board, including one infant, when the crew encountered an abnormal indication involving the No. 2 engine.
Approximately 1 hour and 15 minutes after departure, the flight crew reported a vibration indication associated with the No. 2 engine and advised ATC that they would be returning to Atlanta. The transatlantic flight was discontinued, and the crew coordinated the return and emergency response with Atlanta ATC.
Delta 30 remained airborne for approximately 2.5 hours after departure while returning toward ATL. ATC coordinated the aircraft’s arrival and alerted airport fire and rescue personnel, who prepared for the aircraft’s landing.
The Boeing 767 subsequently landed on Runway 9L and stopped for an external inspection. Airport emergency personnel checked the aircraft for signs of fire, smoke, fluid leakage and other visible abnormalities. No visible fire or smoke, apparent fluid leaks or obvious tire problems were reported during the inspection.
The crew also discussed the aircraft’s brake condition during the post-landing sequence, including a brake-temperature indication while preparing to taxi back toward the gate.
The pilot–ATC communications provide a detailed sequence of the event, from the initial engine-related indication and decision to discontinue the flight, through the return to Atlanta, landing and post-landing emergency response.
This video combines the flight path with the pilot–ATC communications to reconstruct how Delta 30 handled the engine-related abnormality and returned safely to ATL.
