Thirteen survived the initial impact, including the first officer (co-pilot) and one flight attendant, but three of them ultimately died from severe burn injuries. One of the initial survivors died of injuries 29 days after the accident. While investigating this accident the NTSB reviewed the cockpit voice recorder and found that the flight crew engaged in unnecessary and 'nonpertinent' conversation during the approach phase of the flight, discussing subjects "ranging from politics to used cars."
