A child is passed along a human chain of people after being pulled from the rubble of the Plaza Towers Elementary School in Moore, Okla., and passed along a human chain of rescuers Monday, May 20, 2013. A tornado as much as half a mile (.8 kilometers) wide with winds up to 200 mph (320 kph) roared through the Oklahoma City suburbs Monday, flattening entire neighborhoods, setting buildings on fire and landing a direct blow on an elementary school.
