Quite right. Photos of steel buildings after major fires don't show
melted steel, but the steel framing is typically severely deformed &
twisted from heat effects. Take that same type of damaged structural
framing and put a 20-story or 40-story concrete and steel building on
top of it, and you don't need a tinfoil hat to imagine a structural
failure even without taking out a few columns with a jetliner impact.


One thing that the conspiracy theorists never mention, is the plane
that crashed in PA. How would you explain that?

I'm going with gravity.
