Editors Note - this entry first appeared on last year's Daily Nightly.
It's hard to believe that five years have passed since September 11, 2001, because I remember the day as if it were yesterday. As an NBC News correspondent I raced to lower Manhattan that bright, crystal clear morning, and, like so many others, I struggled to stay in control of my emotions in order to do the job of reporting on what had happened.
After the Twin Towers crumbled I remember being at Ground Zero and there was ash falling from the sky like a blanket of rain. I picked up a handful of it and asked a fire captain, "What is this?" And he said it's "pulverized concrete from the Twin Towers".
I shuddered at the thought. If buildings of brick and mortar and concrete had been crushed to dust how on earth could any one who had been in those towers possibly survive?
While the first responders talked hopefully of their determination to rescue victims, even the sounds around Ground Zero suggested it would not be.
There was no sound. The silence was frightening and telling. I'll never forget it.
