Relatives of the victims of the Spanish airliner which crashed upon takeoff earlier this week have begun the difficult task of identifying their loved ones. DNA samples are also being taken to help identify victims as many of the bodies were burnt beyond recognition. Meanwhile, Investigators of the Spanair plane crash are examining the aircraft's black box recorders for clues into what caused the jetliner to go down. Airline officials are still refusing refuse to speculate on what caused the crash that killed 153 people.
