韩亚航空客机旧金山失事 2名中国女生遇难

Bill Waldock, an expert on aviation accident investigation, said he was reminded of the Heathrow accident as he watched video of Saturday's crash. "Of course, there is no indication directly that's what happened here," he said. "That's what the investigation is going to have to find out."

The Asiana 777 "was right at the landing phase and for whatever reason the landing went wrong," said Waldock, director of the Embry-Riddle University accident investigation laboratory in Prescott, Ariz. "For whatever reason, they appeared to go low on approach and then the airplane pitched up suddenly to an extreme attitude, which could have been the pilots trying to keep it out of the ground."

Asiana is a South Korean airline, second in size to national carrier Korean Air. It has recently tried to expand its presence in the United States, and joined the Star Alliance, which is anchored in the U.S. by United Airlines.

The 777-200 is a long-range plane from Boeing. The twin-engine aircraft is one of the world's most popular long-distance planes, often used for flights of 12 hours or more, from one continent to another. The airline's website says its 777s can carry between 246 to 300 passengers.

The last time a large U.S. airline lost a plane in a fatal crash was an American Airlines Airbus A300 taking off from JFK in 2001.

Smaller airlines have had crashes since then. The last fatal U.S. crash was a Continental Express flight operated by Colgan Air, which crashed into a house near Buffalo, N.Y. on Feb. 12, 2009. The crash killed all 49 people on board and one man in a house.
