San Francisco plane crash

It remains uncertain how Ye Meng Yuan, 16, died. San Francisco police officials who spoke about the incident today said that she was found on the ground at the runway, covered by foam the fire crews were spraying on the smoldering jet.

When the jet came to a rest, passengers were first instructed to stay put. It was another 90 seconds or so before the evacuation order was given. Investigators say pilots sometimes feel it's safer to wait for emergency personnel to arrive. But when pilots realize there's a fire, there's no choice but to get out.

The flying pilot had the day off before the flight to San Francisco. He says he got eight hours of sleep and came to the airport six hours before the flight, says National Transportation Safety Board chief Deborah Hersman. The plane's crash-landing Saturday killed two passengers and injured dozens.

Of three experienced pilots in the cockpit of Asiana Airlines Flight 214, the pilot landing the plane had never before flown with the instructor pilot. And the trip was the instructor's first in that capacity. When the plane crashed, two flight attendants were ejected from the rear of the cabin.

Among the things officials want to know: How much training had the pilot received before taking the controls of a Boeing 777; and what was the "training pilot" on board doing at the time of the crash?

Investigators are interviewing the four pilots of Asiana Airlines Flight 214 today. At a briefing, the NTSB says that three seconds before Saturday's crash-landing, the aircraft's speed was 103 knots — the lowest measured by its data recorders, and far below the target speed of 137 knots.

A "plane spotter" who was recording as jets came in to San Francisco International Airport on Saturday captured video of the accident. It shows the aircraft hitting the ground and sliding down the runway. Remarkably, 305 of the 307 people on board survived.

At a Sunday news conference, the head of the NTSB also said that about 7 seconds prior to impact there was a call to increase speed on the jetliner. Saturday's crash at San Francisco airport killed two Chinese teenagers and injured dozens of others.

Video reports show smoke billowing from Flight 214 and it appears to have broken into at least two large pieces. Images from the scene also show many passengers walking away from the crippled jet.
