This episode of Modern Marvels examines the most extreme raging fires and the firefighters who tame them. The program features interviews with a World War II firefighter who helped contain the London’s blitz fire. We also meet “Hell Fighters” who fight raging oil well fires, and “smoke jumpers” who parachute into forest fires. Firefighting: Extreme Conditions also takes a look at how NASA guards against the very real risk of a fire aboard a space vessel.
