Kevin Ryan of underwriters stated ..test on the steel done at maximum possible temperatures for extended periods of time caused no weakening of the steel....
Can you please supply me with that quote from Kevin Ryan? I would like to read it for myself from the same source you are.
I supplied you with the video of that to watch before where he says all of that.You never bothered to watch it like you 9/11 apologists NEVER do since as we both know,you only see what you want to see and hear what you want to hear.
Kevin says they proved the floors sagged a bit in the tests.
Uh oh!
Now what?
