Flights were set to resume Sunday on the runway a Turkish Airlines Boeing 737-800 was heading for when it crashed four days ago, killing nine crew and passengers. The runway at Amsterdam's Schiphol Airport had been closed to all air traffic since Wednesday's crash that also injured dozens of passengers. Flight TK1951 slammed into a muddy field one mile short of the runway and broke into three pieces. Dutch Safety Authority spokesman Fred Sanders said investigators were still examining the wreckage for clues to the cause of the crash. They expect to be able to give a preliminary report next week.
