A Spanish judge will question three mechanics on suspicion of manslaughter in the Spanair plane crash that killed 154 people at Madrid's airport in August, AP quoted a court spokesman as saying Thursday. Judge Juan Javier Perez of Madrid's Superior Court subpoenaed two mechanics who checked the plane before it crashed on takeoff, as well as the Spanair maintenance chief at Madrid's Barajas airport, the spokesman told The Associated Press anonymously due to court regulations. None of the mechanics has been charged.
