Steven Jones is Experimenting
Former BYU professor Steven Jones, who apparently has more time on his hands now that he is retired, has finally started to experiment with recreating his theoretical thermite demolition device. This has been a major criticism of him for a while, so I have to give him credit for at least trying. He claims this device was shown to be able to cut through structural steel, and provides a photograph of his "proof of concept".
OK, I know this is just a "proof of concept", but I think the steel beams in the World Trade Center were a little bigger than that....
Jones later goes on to quote the NFPA 921 Guide for Fire and Explosion Investigations:
"Unusual residues might remain from the initial fuel. Those residues could arise from thermite, magnesium, or other pyrotechnic materials."
This is standard for fire and explosion investigations -- Why was the standard not applied to the WTC "crime scene"? I'm saying it should be. And as with other crime-scene investigations, once a pyrotechnic material's presence has been established, then the next step is a criminal investigation to determine who planted the pyrotechnic (such as thermate).
Uhh, Dr. Jones, that is for cases of arson, not airplane crashes. Even you aren't claiming the fires at the World Trade Center were started with thermite. Notice that thermite is used as an incendiary, not an explosive.
