A year after 9/11, a common theme in almost everything written or said about that day is how much things have changed in America since then. Usually the change has to do with how we act or think about things. But in New York City, the changes created new facts on the ground - and in the air, as well.
The Twin Towers were more than landmark office buildings and icons of capitalism. They also constituted one of the world's biggest lightning rods. Each was topped by a copper grid attached to the building's steel frameworks to harmlessly conduct lightning bolts to the ground. Scientists guess that about 35 serious strikes per year that might have hit elsewhere in lower Manhattan were instead absorbed by the Trade Center. In August, a man was killed by lightning on a rooftop in Greenwich Village. Indirectly, he may have been another victim of 9/11.
