Nothing much can be added that hasn't already been said and repeated hundreds if not thousands of times since that morning in 2001. The world indeed changed and it's become a place where everyone remembers exactly where they were and exactly what they were doing when the unbelievable news broke. And now we reflect on that ancient Chinese Curse that we are indeed living in interesting times.
So my two cents, as way of memorial and witness to history comes in the form of an excerpt from NPR's Morning Edition broadcast of September 11th, with a shocked and dismayed Bob Edwards fielding reports from an equally shocked and dismayed staff.
Nothing more can be added. History has done the rest.
