** FILE ** A crane is seen attached to the Deutsche Bank building in New York, in this Dec. 7, 2006 file photo as the building, which was damaged in the Spet. 11, 2001 terrorist attacks, is dismantled one floor at a time. New York City officials this week said that they believe careless smoking by demolition workers started the Aug. 18, 2007, fire which filled the tower with a lung-searing soot that killed two NYC firefighters.
