 I'm Larry Collins, I'm the Deputy Chief of Special Operations on Hazmat Section at Cal OES Fire and Rescue. On that day I was a fire captain in charge of the Urban Search and Rescue Unit, the central Urban Search and Rescue Company which is called USAR Task Force 103 at a fire station in the East Los Angeles area. It comes into the south side and then boom. Then the second plane hit, the second tower and everyone knew right away the US is under attack. They deployed a number of West Coast Urban Search and Rescue teams from California. I got assigned to as a division supervisor at the Pentagon. We went on the assumption from the very beginning that we're looking for survivors and we'll look for survivors until we can search every survivable void space and determine that there's no more survivors left. After about 12 days we were able to finally determine that we have gotten everybody out of this thing to the tune of about 158 people or so. Initially when we got to the World Trade Center I didn't anticipate seeing something like that that had been done on purpose. When you see that footage in the lobby and you see the firefighters going up those stairwells, they knew that that may be the last time they've ever been seen. To me that's the overriding lesson of 9-11 and most of the disasters we go to is that you see the best of humanity sometimes along with the worst. That buoys us and it also tells us at Cal OES that the planning we do, the training we do, all the preparation, the collaboration and coordination that we do ahead of the disasters, it matters because when these systems come together and work we know that lives are saved.
