The captain of a Pakistani airliner that crashed last week, killing 97 people on board, approached Karachi airport without announcing he couldn’t open his landing gear and hit the runway three times, a government minister said on Thursday.

Search teams recovered the cockpit voice recorder from the wreckage of the Pakistan International Airlines Airbus A320 that crashed into a residential neighbourhood of Karachi last Friday, a spokesman for the airline said. Two people on board survived.
