Just curious, did you watch the video and have an answer?

Yes. You had 2 jets crash into buildings, stripping the support structure of its heat resistant coating, after which the pools of jet fuel burned, heating the underlying metal until it softened enough to no longer be able to bear the weight of the structure (far below the full melting point and replicated multiple times now) causing the collapse. These things did so much damage to the adjacent building 7 that it also collapsed.

Have you ever actually done research into the reports that thoroughly debunk nonsense like this video?

What is the burning temperature of jet A fuel at standard atmospheric oxygen levels?

Ok, now what is the re-crystallization temperature point of structural steel? (I will even leave out any 'heat resistant coatings' bs)

Finally, if you can describe how glowing red hot steel beams were pulled from the ground (a non-oxygen rich environment) months after claimed jet-A fuel fire, then we can start having an engineering discussion on how 4digit celsius temperatures might have been reached.

You don't need to reach melting temperature to affect a steel structure - you can weaken the steel and produce strange unplanned loads at lower temperatures and cause failure cascades. Here is the NIST story about WTC7: https://youtu.be/PK_iBYSqEsc Myles Power made a video about WTC7: https://youtu.be/7PpsCCTMP8w I don't endorse him on other topics, but this particular video is good.

EDIT: You can see how a furnace is built on the Primitive Technology channel. It requires insulation, a source of air, and combustible material - all things the rubble contained. NYC is riddled with tunnels, so the air supply is not a problem. The building provided both insulation and material to burn.
