After a devastating tornado rolled through Moore, Okla., last May, firefighters were scrambling to pull people out of storm shelters. Actually finding those shelters, though, was difficult. Landmarks had been swept away, and the town's emergency dispatcher was overwhelmed with calls.
"Yes, we're at 604 South Classen. There's people down," one caller said. "We're stuck under rubble. ... Please hurry."
Shonn Neidel was one of the firefighters rushing to rescue people that day, and he quickly saw a problem.
