Asiana Plane Crash :Piolet try to abort before landing

The Asiana Airlines Boeing 777 that crashed at San Francisco's airport on Saturday was flying "significantly below" its intended speed. Moreover, its crew tried to abort the landing less than two seconds before it hit a seawall in front of the runway, the U.S. National Transportation Safety Board said, on Sunday.

Asiana Airlines said the pilot in charge of landing the Boeing 777 on Saturday was training for the long-range plane and it was his first flight to that airport with the jet. Asiana Airlines said he had previously flown to San Francisco on different planes and was being assisted by another pilot more experienced with the Boeing 777.

Information collected from the plane's cockpit voice recorder and flight data recorder indicated that there were no signs of trouble until seven seconds before impact, when the crew tried to accelerate, NTSB Chairwoman Deborah Hersman said at a news conference at the airport.

Two Chinese teenagers died in the incident and more than 180 people were injured, local officials said. In a tragic new twist, the San Francisco Fire Department said that one of the teenagers may have been run over by an emergency vehicle as first responders scrambled to the scene.
