From a story in the WSJ eyewitness Pax making his 173rd flight inti SFO:
Mr. Rah saw a flight attendant carrying injured passengers down the aisle. "She was a hero," he said. "This tiny, little girl was carrying people piggyback, running everywhere, with tears running down her face. She was crying, but she was still so calm and helping people."
Mr. Rah said the flight attendants got everyone off the plane as the smoke billowed inside.
