(Reuters) - The Asiana Airlines Boeing 777 that crashed at San Francisco's
airport on Saturday was traveling "significantly below" its intended speed
and its crew tried to abort the landing just seconds before it hit the
seawall in front of the runway, the U.S. National Transportation Safety
Board said on Sunday.
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.
A stall warning sounded four seconds before impact, and the crew tried to
abort the landing and initiate what's known as a "go around" maneuver just 1
.5 seconds before crashing, Hersman said.
"Air speed was significantly below the target airspeed," she said. |
