A United Airlines flight traveling from Washington Dulles International Airport made an emergency landing last month after the pilot declared a mayday call shortly after takeoff due to engine failure.

British Midland Flight 92 (Boeing 737‑400, January 1989): A fan blade fracture caused a fire in the left engine, and the pilots misdiagnosed the malfunction and shut down the right (healthy) engine, leading to loss of thrust and a crash which killed 47 on board. The incident became a cautionary tale in engine-identification training .
