ARLINGTON, Va. — Firefighter Ray Hodgson hits the talk button on his walkie-talkie: "I have fire showing, possibility of a rescue on the third floor. Engine 35, initiate a rescue group. Also back him up with a hose line."

A fire has been set in a three story building at the Maryland Fire and Rescue Institute, where firefighters hone their skills and test equipment. In this case they're testing a device they hope will save firefighters' lives. Everyone taking part in the drill knows how difficult and dangerous it is to locate a missing firefighter in a smoky inferno.
