“There were a lot of firsts for the WTC. In all the history of high-rise fires, not one has ever been hit with a plane traveling 500 miles an hour and had its fire proofing removed from its trusses. In all the history of high-rise fires, not one has ever had its steel columns which hold lateral load sheared off by a 767. In all the history of high-rise fires, not one has ever been a building which had its vertical load bearing columns in its core removed by an airliner. For Building 7, in all the history of high-rise fires, not one has ever been left for 6-7 hours with its bottom floors on fire with structural damage from another building collapse. Not the Madrid/Windsor tower did not have almost 40 stories of load on its supports after being hit by another building which left a 20 story gash. The Madrid tower lost portions of its steel frame from the fire. Windsor’s central core was steel reinforced concrete. In all the history of high-rise fires, not one has ever been without some fire fighters fighting the fires.

I could go on with the “Firsts” but you get the drift. The statement that the WTC buildings were the first high-rise buildings to collapse from fire is deceptive because it purposely doesn’t take those factors into account”.

Sure because the strength of the nail is more than sufficient to support the hammer.

When the towers began their collapse, in the first 3 meters of movement as the first floor failed, momentum increased the mass presented upon the floors below by 30x its static weight.
This now presents a load to each floor as the building crumbles of about 15x their maximum safety factor.

Tell me how much is your hammer going to be slowed if you swing it at a toothpick? a 3 inch piece of a guitar’s E string?

All of this has been calculated by experts.

To think that a 767 loaded with fuel could not take down just about any building on the planet is to stand up and say I am an idiot.
