Yeah, it was totally an Airplane... For sure.

I thought jet fuel melted steel? Humm.
Makes me wonder what jet engines are made out of...

Interesting. Still, melting points of nickel is around 2600 degrees F. Aluminum is around 1200, and steel is anywhere between 2500-2800 according to google. And not really any clear answers on what jet fuel burns at. Because I will not use the 2000 degrees C. Those temps are reached inside the jet engine, not in open air. In the engine the air is super compressed making it a bazillion times hotter inside that engine. But once exposed to the open environment, would disperse and immediately burn much cooler.
Jet fuel also has the amazing property of causing controlled demolitions as well. For instance, the Twin Towers in New York.
Depending on the alloy Steel does indeed have a fairly wide temperature range. Actually it's one of the reasons other than cost that we don't just use Stainless Steel everywhere is that it has a lower temperature range than plain Carbon Steel as well as the differences in tensile strength. That corrosion resistance comes at a price other than cash.
Jet fuel, chemically, is a lot like kerosene. Jet A1 fuel. Nothing top secret about it.
For sure.

Structural Steel starts to lose strength at around 700* F, and is below half strength around 1000* F. So melting isn't required for materials to fail. Materials used inside jet engines are designed to operate within their strength tolerances at their operating temperatures, which is not flame temps. One of the tricks to maintaining material strength in a jet engine is boundary layer air flow over the turbine blades and other parts subjected to high stress.
A raging building fire can easily reach 1800* F. Jet fuel wouldn't increase the temperature much, if at all. Unless it's contributing to a chimney effect - pulling in air with enough velocity to make a fire hotter. A blast furnace can melt steel, and I think they get to around 3000* F.
Anyway, just some basic info on materials. Not a commentary on anything.
Good, this meme needs to die...

Interesting, but how long did that steel have to remain in the forge? How long did it take for the jet fuel to fully burn off? Why was there liquid, glowing metal flowing out of the buildings before the collapse? Why did the buildings collapse uniformly at freefall speed into their own footprint? And the icing on the cake, why was unreacted thermite found in the debris from the building by that university professor in Denmark?
-Not as long as the burning plane and burning debris.
-Does it matter once it got going?
-Gee, lets not look for possible explanations.
-It didn't freefall. It took 11 seconds to collapse from 1368ft, not 9.2 seconds.
-What is thermite composed of? Why wouldn't a sky scrapper contain the same elements? What makes a university professor back then more credible than university professors today?
Was the WTC designed to support 10 upper floors buckling like this? https://imgur.com/a/CxjxUmN
-The burning aluminum plane. Gotcha -What difference, at this point, does it make? -The 9/11 commission sure didn't -Let's set the time aside. With the plane allegedly damaging the structure on one side, why didn't it fall sideways instead of straight down? -So, your hypothesis is that thermite spontaneously formed as the towers were collapsing? What person who did materials analysis claimed there wasn't thermite or that it's presence was explainable by your hypothesis? -Irrelevant, there was no resistance beneath it
Only steel and concrete not paper.
It also makes buildings come crashing straight down in a very tidy manner.
No, dummy. Only office furniture fires get that hot, and then only when accelerated by printer paper. Science!
