As Oklahoma City residents and emergency crews continue to search for survivors in the wreckage left behind by Monday's deadly tornado, stories of survival and heroism are keeping spirits up.
One man, James Rushing, rescued his 5-year-old foster son from the wreckage of his school, Plaza Towers Elementary School in Moore, Oklahoma, the suburb hit hardest by the twister:
Damian Britton, a student at the same school, told NBC News that he credits his brother's sixth grade teacher, Rhonda Crosswhite, with saving his life:
"We heard the sirens go off and then we all ran into the hallway," Damian said. "Some of us had a math book and some of us had our backpacks. (The sirens) went off again, and we ducked again. They went off again, and then we heard the tornado and it sounded like a train coming by, and then we were all in cover."
