Search & rescue teams face tough assignments in Oklahoma
Help for the people in Oklahoma has been flooding in from all over the country, some in the form of Urban Search and Rescue teams. It's very technical, very physically demanding and emotionally draining. On the ground, after dark at the Plaza Towers Elementary School where seven children lost their lives in the tornado urban search and rescue teams, some from the military, are working through the night hoping that someone will still be found alive.
