I would guess that there were spaces like windows and framed walls that would succumb to large jet engines traveling at 500kts hitting them and allow them to pass from one side of the building out the other, including the fireball from the jet fuel. I doubt the structural steel and masses of strengthened concrete were all that much impacted. So I don't see an argument about the jet passing into the building and being largely contained by the steel and concrete being useful for discussion purposes. Clearly the biggest argument for this being a planned event is building 7 collapsing into it's own footprint at free fall speed from random paper fires. This is impossible, the University of Alaska engineering dept studied it for 4 years and said the same. So if just one incident of that day can be proven to be planned, like wiring a building for demolition, then the whole 9/11 attack by terrorists is a contrived false flag, regardless of the presence of terrorists flying planes or not. We don't need to get bogged down with some of the non-supporting evidence for that conclusion. If building 7 was brought down by demolition then the 9/11 public narrative is false, which it is. Now the question is who is responsible, clearly this goes to the highest levels of our gov't and is on par with the Covid scamdemic. So it's likely done by the same group of people. That's just a guess, I'm open to alternative theories.
