2008: British Airways Flight 38, a Boeing 777-200ER G-YMMM, flying from Beijing to London, crash-landed approximately 1,000 feet (300 m) short of London Heathrow Airport's runway 27L, and slid onto the runway's threshold. This resulted in damage to the landing gear, the wing roots, and the engines, resulting in the first hull loss of a Boeing 777. There were 136 passengers and 16 crew on board. 1 serious and 12 minor injuries were sustained. The initial report from the Air Accidents Investigation Branch stated that the engines repeatedly failed to respond to commands for more thrust from both the autothrottle system and from manual intervention, beginning when the aircraft was at an altitude of 600 feet (180 m) and 2 miles (3.2 km) from touchdown. In September 2008, it was revealed that ice in the fuel might have caused the crash. In early 2009, Boeing sent an update to aircraft operators, identifying the problem as specific to the Rolls-Royce engine oil-fuel flow heat exchangers.
