That was regarding the molten metal pouring out the side near the impact crater, not the temp. recorded in the debris months after the collapse. That is what the poster you responded to was referring too. You made it sound ike the blog had an answer for that but was talking about something different and since you didnt quote anything from your source it gave the impression that the blog had an answer to the posters question when it didnt appear to address it at all.

Not my buddies blog. Don't even know who the writer is. I'm on my phone. It's nearly impossible to copy paste links with any degree of ease. As such I won't. I think you asked about molten metal. I linked you to a page. About half way down on the classic view is a whole load of stuff related to that.
What part of the blog is full of b.s.?

Sorry..I misunderstood. You want the temps in the crater justified? Water on hot steel, runaway exothermic reaction, splits into h and o. I think that's what it says, I'm not going back to check. I'd rather watch 'the great British bakeoff'.
In the interim, maybe you can give me your opinion.

Look! The whole page is called molten steel. It's all about molten steel. I didn't just say go look at this site.
Go on, be a sport, give me your theory as to the steel. You said earlier you worked with steel. 5th biggest in lower mainland B.C. from what I recall. You must have a clue.

The reaction between IRON AND STEAM is also very EXOTHERMIC and fast at temperatures above 400 deg C. This reaction produces Fe3O4 AND HYDROGEN. It is the classic example of a REVERSIBLE REACTION studied in Chemistry labs at high school. But believe it or not, back at the turn of the century, the reaction of iron and steam was used as an industrial process for the manufacture of hydrogen.
I think iron and steam could have reacted in this way (at least for a while) and generated a lot of heat. What is more, the hydrogen released would have been converted back to water by reaction with oxygen, thereby generating even more heat. In this case spraying water on the rubble pile was like adding fuel to a fire!

Lets state some FACTS , first I am NOT from the USA .
This is the MOST IMPORTANT FACT nobody on EITHER SIDE can ever know the extent of the damage done by the aircraft.
So was structural damage done YES
Can office fires reach temperatures to weaken steel YES
sure but I want to see a video of it and that doesn't explain how concrete became dust.
Can a progressive collapse happen YES.
So could what we saw that day happen YES!!!
There was NO personal attack directed towards YOU, if so please point it out!
Has an office fire ever caused a progressive collapse in a steel-structured highrise? NO.

Yes there has.
Delft
And to think it all started when a vending machine overheated.
Look familiar?

The second most important thing to remember is that there was ZERO structural damage to any floors below the impact. There was no heat below impact
NIST
Immediately after collapse initiation, the potential energy of the structure (physical mass of the tower) above the impact floors (94th to 99th in WTC 1 and 77th to 85th in WTC 2) was released, developing substantial kinetic energy. The impact of this rapidly accelerating mass on the floors directly below led to overloading and subsequent failure of these floors. The additional mass of the failed floors joined that of the tower mass from above the impact area, adding to the kinetic energy impinging on the subsequent floors. The failure of successive floors was apparent in images and videos of the towers’ collapse by the compressed air expelled outward as each floor failed and fell down onto the next. This mechanism appears to have continued until dust and debris obscured the view of the collapsing towers.
As the composite floor decking was most likely quite rigid due to the continuous concrete floor, the transverse bridging trusses, and the intermediate deck support angles, failure of the floor as a whole would be expected at the connections attaching the floor to the exterior wall and core.
With magic fire and forces strong enough to pulverize concrete to dust... maybe.

The columns were 50cm x 50cm over the full height of the building, with the amount of reinforcement decreasing with height.
The floor system consisted of a series of reinforced concrete joists running in the east-west direction between girders. Typical details are shown in Fig. 12.
