San Francisco fire chief Joanna Hayes-White said there were 291 passengers on board in addition to 16 crew. She told a press conference that 48 people were transported to hospital and a further 190 people self-evacuated to safety. More than three hours after the crash, "upwards of probably 60 people remain unaccounted for at this time," the fire chief said.
Authorities did not initially release any information about casualties or the causes of the accident, but ruled out terrorism.
Television pictures showed a trail of debris, including the plane's severed tail fin, from the start of the runway at the edge of San Francisco Bay, prompting aviation experts to speculate that the plane's tail section struck the runway first.
"This is very obvious what happened," aviation industry consultant Robert Herbst told Bay Area News Group. "They landed short of the runway. They were too low for the flight path and the tail of the aircraft hit the sea wall."
"They did land substantially short of the runway," Todd Curtis, a former aviation safety expert with Boeing, told CNN.
The crash sparked a rush of interest on social media, especially after a passenger on the flight posted a photograph of the plane seconds after the accident. It showed the emergency chutes deployed and passengers running away.//DPA
