On August 31, 2009, the National Geographic Channel aired the program "9/11 Science and Conspiracy", in which the Energetic Materials Research and Testing Center tested some of the claims frequently made by those who question the accepted 9/11 account. Specifically, the experiments concluded that burning jet fuel alone can sufficiently raise the temperature of a steel support column to the point of structural failure, that a controlled demolition using conventional techniques would leave clear evidence that was not found at Ground Zero, that using thermite is not an effective technique to melt a steel column, and that even if thermite chemical signatures were found, it would be impossible to tell if thermite was actually used or if the traces came from the reaction of aircraft aluminum with other substances in the fire. The testing also concluded that the type of hole found at the Pentagon was consistent with the standard scenario, and that damage from a bombing or missile attack would differ from the damage that occurred. In the program, several prominent 9/11 conspiracy theorists viewed rough edits of the experiments, and expressed their disagreement with the findings.
