NTSB Provides First Scene Update on Fatal Plane Crash

National Transportation Safety Board chairwoman Deborah Hersman spoke to reporters Sunday afternoon for the first time since Saturday's deadly plane crash at San Francisco International Airport.

Hersman explained the agency's investigation of the Asiana Airlines Flight 214 crash, which occurred at about 11:30 a.m. Saturday and left two people dead and dozens injured.

NTSB officials have been able to listen to the cockpit voice recorder as well as the flight data recorder, which captured the entire flight from Shanghai, China, to Seoul, South Korea before traveling to SFO.

According to Hersman, the airspeed of the plane was slow -- below the target airspeed. 

The plane, a Boeing 777, has a tail No. HL7742 and line No. 553. The plane had a factory rollout of February 2006, and its delivery occurred one month later. It holds 333 seats -- 32 of which are business and 271 are economy.

Hersman also said that three of SFO's four runways have been reopened since the crash.
