On the morning of September n, 2001, some 3000 people died in front of our eyes in a crazy scene of airliners crashing into skyscrapers and of those skyscrapers crumbling within minutes. Anyone downtown in Manhattan that day, or anyone anywhere in front of a television screen who watched the collapse of the twin towers of the World Trade Center, has the memory of it seared into their psyche. The entire appalling event—from Manhattan to the Pentagon to a small field in Shanksville, Pennsylvania—sent political shockwaves across America and around the world that have not yet subsided. We now call that day 9/11 as a signature shorthand for the catastrophe, a logo for an event whose details quickly occupied the mind of nearly everyone on the planet.
