I was at home, my wife called me from work.
I turned on the TV to see just one tower, the other was already gone.
I called my friend, telling him to turn on the TV.
In the background I could hear his wife: "OH MY GOD! OH MY GOD! OH MY GOD!"
Went in to work, but they sent us all home.
Later, I was watching a show about it. About the firefighters. They happened to have a film crew with them for a ride along.
They were in the lobby of one of the towers, documenting the firefighters coordinating their response.
And every now and then, you'd hear *WHAM*. Something hitting a roof. No regular interval, just *WHAM*, *WHAM*, *WHAM*, in the background.
Those were jumpers. Landing.
Never Forget -- it's a promise.
