WASHINGTON (AP) — NTSB Chairman Deborah Hersman says federal investigators based in Los Angeles are traveling to San Francisco.
At a briefing in Washington, Hersman said she and other NTSB personnel in the nation's capital were expected to arrive in San Francisco on Saturday evening.
She said they have not yet "determined what the focus of this investigation is."
Investigators from South Korea were being invited to participate in the probe.
She said the team's first job will be to collect information and document the accident scene.
The Asiana Airlines flight from Seoul, South Korea, crashed while landing at San Francisco International Airport on Saturday, critically injuring at least 10 people and forcing passengers to jump down the emergency inflatable slides to safety.
