A lot of the bondsmen/traders kept phones on speaker with their colleagues in other countries. Apparently, their British counterparts heard everything, from the time the first plane hit until all their American colleagues were dead. From what I've read, they were traumatized by all they heard, people crying, calling loved ones, coughing, trying to find a way out, talking about jumping, and finally, dying. I read this in the first days after the attack, and never heard much about it after. But it stuck in my mind, imagine being an ear witness to all that horror. Worse though, were the people that watched the jumpers and the results on the sidewalks. The media won't show you the jumping anymore, but I have a friend who is a NYC Fireman, and he showed me pictures of the aftermath of the jumps. Shocking, awful. I will never forgive or forget the scum that did this.
I ran across a DVD in Sam's that was a documentarty made by those French photojournalists. They were inside the WTC shortly after the planes hit and the sounds of the bodies hitting the pavement souded like bombs going off. All the firefighters jumped whenever it happened and I got the impression it was really hard for them to take. They all looked real shook up about it. It was an awful sound. And to know that it was somebody's life that had ended. It was a tough video to watch, but I'm glad I got it. I wish I had got more. We need to remember.
