**FILE** This Feb. 21, 2003, aerial file photo shows the burned-out ruin of The Station nightclub in West Warwick, R.I., where 100 people died after a pyrotechnic show by a rock band ignited foam used as soundproofing. The Station disaster, and a stampede at the Chicago's E-2 nightclub in February 2003 that killed 21 people, inspired some improvements in crowd safety, but experts say more could be done.
