Boeing 777 plane crash-lands at San Francisco airport

6 July 2013 Last updated at 21:37 GMT A Boeing 777 aircraft has crash-landed at San Francisco international airport, killing at least one person and injuring as many as 30, diplomats say. Pictures posted on Twitter showed passengers jumping down the inflatable emergency slides and leaving the area, as plumes of smoke rise from the plane. Firefighters and rescue teams are at the scene of the downed Asiana Airlines Flight 214, which had taken off from South Korea's capital, Seoul. The cause of the crash is unclear. Early indications suggest the plane came in too short and hit the seawall at the airport.

While the sequence of events remains unclear, it appeared the plane landed and then crashed on San Francisco International Airport's Runway 28L, said Federal Aviation Administration spokeswoman Laura Brown. Footage of the scene showed debris strewn on the runway and smoke pouring from the jet, as fire crews sprayed a white fire retardant into gaping holes in the craft's roof. One engine and the tail fin appeared to have broken away from the main wreckage. "I just crash landed at SFO. Tail ripped off. Most everyone seems fine. I'm ok. Surreal..." Mr Eun, who describes himself as a "digital media guy" and "frequent flier", added: "Fire and rescue people all over the place. They're evacuating the injured. Haven't felt this way since 9/11." A witness to the crash, Ki Siadatan, said the plane "looked out of control" as it descended over San Francisco Bay to land just before 11:30 (18:30 GMT). "We heard a 'boom' and saw the plane disappear into a cloud of dust and smoke," he told the BBC. "There was then a second explosion." He saw events unfold from the balcony of his home in the Millbrae area of San Francisco, which overlooks the airport. Weather conditions were fine and there was little wind, he added. Arrivals and departures at the airport have been suspended since the incident. The twin-engine Boeing 777 has a good safety record as a long-haul aircraft and is used by many major carriers. Asiana is South Korea's second-largest airline.
