The steel members of both buildings failed. That alone debunked your argument that no steel supported buildings failed in a fire.The paper factory was a high-rise?
The Windsor Tower was under construction and only part of the floors above 17th floor collapsed and not to forget that the building burned for almost 20 hours under raging fire, while we have not one pic of the WTC 1, 2 and 7 showing any similar situation.
You want some more...???
First...Look at all these steel supported/built buildings that failed when their steel members failed in some ways...

Second...From the above source, one of them is the Kader Toy factory whose steel members failed under constant heat, not struck by anything, but just from heat.

But wait...There is more......the building was reinforced with un-insulated steel girders which quickly weakened and collapsed when heated by the flames.

The Alexis Nihon Plaza building basically collapsed due to fire. No aircraft struck this building and that is why the steel members lasted as long as they did before they collapsed. The argument that it must be a high rise is absurd and nothing more than a feeble attempt to escape the truth.The Alexis Nihon Plaza fire in Montreal, Canada occurred on October 26, 1986 (Isner, 1986). The building was a 15-story steel-framed office building that was built atop a wide 5- story concrete mall and parking garage. This complex included an adjacent 23-story office building and a 32-story apartment building, all supported by this concrete plaza. The 15-story office tower had conventional steel framing, consisting of steel beam and deck floors and steel columns. The beams and floors had a 3-hour fire rating, while the columns had a 2.5-hour rating. All building elements were insulated with spray-applied mineral fiber. There was no automatic sprinkler system installed in the building. On October 26, 1986 a fire began on the 10th floor, then spread to the 11th and 12th floors, and later to the top floor. Approximately five hours after the fire started, a section of the 11th floor collapsed onto the 10th floor. The fire was declared out the following morning. There were no fatalities or injuries.

The above is a credible source that showed a history of fire that failed steel structures.

Your argument is done, as in completely debunked by science.All materials weaken with increasing temperature and steel is no exception. Strength loss for steel is generally accepted to begin at about 300°C and increases rapidly after 400°C. By 550°C steel retains approximately 60% of its room temperature yield strength, and 45% of its stiffness. At high temperatures, steel is also subjected to significant thermal elongation, which may lead to adverse impacts, especially if it is restrained. It follows therefore that one would expect that structural steelwork which has been subjected to high temperatures would exhibit signs of this in the form of distortion and buckling.
Actually...No.Now show me some charts how a Boeing can fly 2 m above ground at 800 km/h.
If you make a claim, it is up to YOU to support it. Let me guess, you are going to trot out the debunked argument of 'ground effects' ?
Vaporized ?And also how the titanium engines vaporised at impact.
Despite the visual appearance, a jet engine is mostly empty volume, much like your head.
For BOTH of the above jet engine types, the cores are even smaller than the human used for size comparison. The core of the jet engine is the part with the most compact material, and they found the cores of the jet engines from American Airlines Flight 77.
Every time I see hyperbole like 'vaporized', I know the person is not interested in a rational discussion of the issue. I know the person made up his mind. The proper word used by a truly objective discussion would be 'disintegration' because that is precisely what happened.
See the above ? The core's approximate size would be the woman's head and upper torso. The rest are turbine blades that give the ILLUSION of mass. Kinda like how you give us the illusion that you are an intelligent person.
