"Dustification" of Steel Versus Vaporization of Steel
Which seems to be roughly the case, from checking the numbers myself.
Which means, in her own weird way, Judy Wood was right to use "dustification" to refer what happened to the steel, as noted in this comment:

The energy to "dustify" iron depends on the particle size you want to reduce the iron to. Very roughly I estimate ~ 0.7 kJ per kg for 1 micron iron dust or 0.7 MJ per kg for 1 nanometer iron dust. (This is consistent with the vaporization energy of 7 MJ per kg because vaporization is equivalent to atomization and the atomic radius of iron is about 0.1 nm)
So, if you want to vaporize 1 tonne of WTC steel during a tower collapse it would require about 7000 MJ of input energy in 10 seconds or an input power of 700 Megawatts per tonne!. That's the electrical energy output of a typical nuclear power station for 10 seconds, JUST TO VAPORIZE ONE TONNE of structural steel!
As for "dustification" the numbers are, of course, a little better, but you still need a mechanism to fracture steel rather than bend it.
