Quick Calculations

RICH GARLOCK: Going below, it was smoky and really hot. We had rescue teams with meters for oxygen and carbon dioxide. They also had temperature monitors. Here WTC 6 is over my head. The debris past the columns was red-hot, molten, running. I did some quick numbers with Gary Panariello, an engineer from Thornton-Tomasetti, to try and determine what the load on WTC 6 was and how much of the lateral system of the building the contractor could take down. There were a lot of judgment calls; people had immediate needs and needed immediate responses.
