The cockpit voice recorder of the Pakistani airliner that crashed last week was found on Thursday, six days after the passenger plane went down in a crowded neighborhood near the airport in the city of Karachi, killing 97 people on board. The other part of the black box, a flight data recorder, was recovered within hours of the crash. There were only two survivors of the Airbus A320 crash, which was carrying 91 passengers and eight crew members.
