Asiana Jet’s Slow Approach Probed for Clues to Crash

The Asiana Airlines Inc. Boeing Co. 777 that crashed while landing in San Francisco had slowed to almost 40 miles an hour below its target speed before hitting a seawall short of the runway, a U.S. investigator said.

Crash investigators said they don’t yet know why the plane was moving so slowly it was on the verge of losing lift, or whether a pilot with only 43 hours of experience flying that aircraft type was at the controls. All but two of the 307 people on board survived.
