terrible it was, how bad it was, i was right below the north tower. police were telling me to look up because things were falling down and they were afraid it was going to hit us. and i realize it wasn't things falling down, it was a man throwing himself out of the 101st floor. my emotions, i can't tell you what they were. i just froze. i said to myself this is the worst thing i have ever seen. this is the worst situation i'm ever going to face. and then i said to myself, i can't think about that right now. all i can think about is what is the most effective way to handle it. what is the safest thing to do to help these people. let me just focus on my job, the next step ahead. >> one of the initial press conferences you were asked about the death toll. and i want to play you a bit of footage of what you said. >> the number of casualties will be more than any -- any of us can bear ultimately. and i don't think we want to speculate on the number of casualties. the effort now has to be to save as many people as possible.
