Pictures of Ground Zero's cut columns disprove, once and for all, the imaginative theories that claim evidence of the use of thermite at the World Trade Center to induce the collapse of the buildings. Such "evidence" is merely a misinterpretation of the ordinary effects of cutting through the post-collapse remains of a steel structure.
To understand the situation more clearly, I acquired photographs taken by Joel Meyerowitz, the only professional photographer allowed at Ground Zero.
The pictures below show many examples of diagonal cutting in the material saved by NIST:
- The demo slab was far thicker than any core column.
- The cutting speed was also astonishing.
- Once cutting had begun, it continued at the rate of several inches per minute.
- It goes without saying that the dripping material on the back of the slab is molten steel.
