美国联邦当局调查波音777飞机坠毁

 　　WASHINGTON, July 7 (Xinhua) -- U.S. federal transportation authorities are still in the initial stages of their investigation¹ into Saturday's deadly crash landing of an Asiana Airlines Boeing 777 commercial plane at San Francisco International Airport, an official said Sunday.

　　Deborah Hersman, the chairwoman of the National Transportation Safety Board (NTSB), said the investigators² have already talked to law enforcement officials who spoke³ to the pilots Saturday night and hope to interview the pilots of the aircraft in the coming days.

　　"It's really important to put all of the pieces of the puzzle together, to not just understand what happened, but understand why it happened so we can prevent accidents like this from occurring in the future," Hersman said in an interview aired on CNN's "State of the Union."

　　She said the investigators would have to corroborate⁴ "a lot of information," including the radar⁵ data, the air traffic control information, and the flight data recorder parameters⁶.

　　Two Chinese nationals were confirmed killed and more than 180 others injured after the Asiana Airlines flight 214 crashed in landing Saturday. The Boeing 777-200 aircraft carried 16 crew members and 291 passengers, including 141 Chinese, 77 citizens from the Republic of Korea and 61 Americans.

　　According to Hersman, the black boxes of the crashed aircraft -- the cockpit voice recorder and the flight data recorder -- have been sent back to the federal agency's headquarters in Washington D.C. for lab work.
