Chief of the National Transportation Safety Board, Deborah Hersman, cautioned against jumping to any conclusion about what may be behind the crash of Asiana Airlines Flight 214 in San Francisco. "We're gathering factual information. We know a lot, and what we need to do is correlate all that information. We need to put it together and see what it tells us."
NTSB investigators say the pilots of Asiana Flight 214 relied on automated cockpit equipment to control the jetliner's speed as they landed at San Francisco airport, but realized too late they were flying too low and too slow before the aircraft crashed.
The head of the National Transportation Safety Board said the pilot in charge of landing the Asiana Airlines Boeing 777 that crashed in San Francisco tried to correct its course when he saw it was off center and too low as it approached the airport runway at an altitude of 500 feet,
