On February 22, 1978, a devastating freight train derailment drastically altered Waverly, Tennessee, and its place in history. This was one of the worst train explosions of the twentieth century, killing sixteen people, injuring hundreds more, and causing millions of dollars in damage. What could have been dismissed as a single community's terrible misfortune instead became the catalyst for radical change, including the formation of FEMA, much-needed reforms in emergency response training, and the creation and enforcement of national and state safety regulations. Response to the disaster reshaped American infrastructure and laid the groundwork for the future of emergency management and disaster relief … and yet most Americans have never heard of Waverly. Dr. Yasmine S. Ali, an award-winning medical writer and Waverly native, sets out to change this in Walk Through Fire , drawing from over a decade of meticulous research and interviews with survivors, first responders, and other firsthand accounts. Ali weaves a compelling narrative of small-town tragedy set against the broader backdrop of United States railroad history, rural healthcare, and other elements of American infrastructure that played a part in the creation—and the aftermath—of the Disaster.
