The OP is misleading you. You can run up a furnace to very high temperatures just by having a hole that air rushes through (with a fan, or wind). You don't need to reach 2700 to affect a steel structure - you can weaken the steel and produce strange unplanned loads at lower temperatures and cause failure cascades.
Not this dumb shit again...
The guy word for word admits they pulled building 7 aka they made it fall!

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.
