In the wake of 9/11 and Hurricane Katrina, many are asking what, if anything, can be done to prevent large-scale disasters. How is it that we know more about the hazards of modern American life than ever before, yet the nation faces ever-increasing losses from such events? History shows that disasters are not simply random acts. Where is the logic in creating an elaborate set of fire codes for buildings, and then allowing structures like the Twin Towerstall, impressive, and riskyto go up as design experiments?
