Whatever, though, for you to simply assume that WTC 7, a steel framed
building, totally collapsed near free fall speed from fire, you are
definitely not qualified. A qualified engineer would know that steel
framed buildings do not completely collapse from fire. Never. Sorry.

Which, I guess, means all those engineers who spend so much time
devising fireproofing materials for steel structural members
in buildings have been wasting their time all these years.

Imagine the money that could have been saved in the WTC towers
alone -- all that fireproofing material sprayed on the buildings'
steel structure could have been eliminated, and the costly and
inconvenient effort to update the fire protection that was
still not completed when the WTC towers collapsed was a
colossal waste of time.

If only they'd known what you apparently know -- that fire can't
possibly reduce the yield strength of steel and cause structural
failure.

I guess all those web sites with pictures of what happened to
the steel structure of Madrid's Windsor Building during a fire
on February 2005 are fakes too, right?
