Once a flight attendant noticed a fire outside the aircraft, the evacuation began immediately.
The flight attendants worked to get all of the passengers out of the Boeing 777 as quickly as possible, and to fight the fire once it entered the cabin. Emergency responders arrived on the scene about two minutes after the crash.
The Federal Aviation Administration requires it be possible to fully evacuate a plane within 90 seconds.
Two of the emergency slides deployed inside the cabin, Hersman said. Each one trapped and injured a flight attendant.
Of the plane's flight crew, all survived, and six of the twelve flight attendants were hospitalized. Three were ejected from the back of the plane after the tail broke off during impact.
Two of the 305 people on board the plane were killed in the accident, both were 16-year-old Chinese girls.
