Video: San Francisco plane crash: US investigators review video footage in case of 'run over' victim US National Transportation Safety Board chairwoman Deborah Hersman called the possibility that a girl was run over a "very serious issue." Investigators want to make sure they have all the facts before reaching any conclusions, Ms Hersman said, adding that the coroner has not yet determined the girl's cause of death. Part of the tail section of the Asiana jet that crashed at San Francisco International Airport was found in the bay, and debris from the seawall was carried several hundred feet down the runway, the NTSB said Monday in releasing details that suggest the plane hit the seawall. A "significant piece" of the tail of the aircraft was in the water, and other plane parts were visible at low tide, she said. Investigators released a video on Monday showing the heavily damaged plane, with parts scattered across the ground near the airport runway.
