Iron spheres were produced after igniting the red-gray chips. The WTC was not present.
To be precise, some were 'iron-rich' spheres, and others were rich in Silicon. Both Iron Oxide and various forms of Si are present in various paint coatings, so paint is still not eliminated as the source for those chips.
You really should read thru some of the comprehensive criticisms before posting here, since none of your assertions is a new idea. You seem quite unaware of the many point against Jones' conclusions.
You might also be interested to read some of the comments about 'elemental aluminum' and how the red chips did in fact seem to dissolve, contrary to Jones' claims.
And you have failed to prove that the structural steel in the WTC towers (or any of the WTC buildings, for that matter) wasn't weakened by fire. Did you look at the picture of building 5? Are you going to deny the evidence that fire investigators found, and if so on what grounds?
You're just running away from the arguments, it's very weak.
btw, you should also look at the Purdue university models of the plane impacts to get a good idea of the forces exerted on surfaces which had loose fire-resistant coating sprayed on.
Surely you're not going to deny that exposed steel wasn't generally present where the fires started (ie at the impact zones)?
