But his allegations drew a sharp rebuke from UL, which said Ryan wrote the letter "without UL's knowledge or authorization." The company told The Tribune "there is no evidence" that any firm tested the materials used to build the towers.
"UL does not certify structural steel, such as the beams, columns and trusses used in World Trade Center," said Paul M. Baker, the company's spokesman.
Ryan was fired, Baker said, because he "expressed his own opinions as though they were institutional opinions and beliefs of UL."

And again, your statement is not germaine to the issue that Orion and I were arguing over.

Someone had to certify the steel produced by the company (whomever it was) that sold the steel to Rockefeller for the construction of the towers. Maybe not the exact steel used in the construction of the towers but the steel produced by said company. Either that or we might as well be living in a third world country that has no governance on construction materials. What do we pay ASTM, NIST, UL etc. for then?
Which is it?

I just believe that on 9/11/01 those buildings were subjected to something that was so far outside the range of normal that it was never seriously considered.
Can you explain the technical details of this to us? We can look at the maximum damages NIST was able to do to the core, and look at the severed perimeter columns (take them also at their max possible value), imagine whatever trusses are already missing, and assume safety factors for the columns that is typical of commercial housing. That can be our starting point for considering what the fires would then have to do. Does that work? If not, will you offer a revision that suits you?

As far as I have been able to find, these videos were the closest anyone got with video/camera that day. In some of the videos, it appears as if someone took a scapel and neatly cut a section out right down the middle (no telling how deep into the building it went) in addition to the rest of damage that can be easily seen.

UL labs perform metallurgical testing.
Again, the fight between UL and Kevin Ryan was never about whether or not UL tested the steel for the WTC complex. It was regarding whether or not UL certified for higher standard in fire resistance testing. Kevin Ryan states they did. UL says they did not.
