Another expert who served on NIST's advisory committee was Charles Thornton, of the engineering firm Thornton and Tomasetti. Thornton's partner, Richard Tomasetti, was reported to be behind the unprecedented and widely criticized decision to destroy most of the steel evidence. Early on Thornton said: "Karl, we all know what caused the collapse." He was talking to Karl Koch, whose company erected the WTC steel. Koch attempted to clarify as follows. "I could see it in my mind's eye: The fire burned until the steel was weakened and the floors above collapsed, starting a chain reaction of gravity, floor falling upon floor upon floor, clunk ��unk ��unk, the load gaining weight and momentum by the nanosecond, unstoppable. Once enough floors collapsed, the exterior walls and the core columns were no longer laterally supported and folded in."12 This is a description of what was called the Pancake Theory, the most widely accepted version of what happened.
