NOT:
"they did not and could not have completely failed at the same TIME"
They didn't:

That's why the tops of the two towers leaned heavily when they started to collapse.
the supports presented no resistance to the movement of mass downward
In such a large building with many floors above the collapse point, the forces at the collapse point is many times the normal load. There's no way the towers could have resisted total failure once the collapse started. That's what scientists and engineers know, and that's what happened.
Both towers collapsed from the floors that the aircraft entered. The most obvious fact in the world is the aircraft caused the towers to collapse.
You can believe that if you wish, but I don't, and I am not alone in that...nor will I let you or anyone else intimidate me into silence by attempting to make this out to be crazy talk or by insisting that I am stupid if I doubt the official story.
Your personal incredulity is not evidence. I'm not trying to silence "truthers" any more than "truthers" are trying to silence people that support the scientific consensus.
So what was the cross sectional area of the WTC buildings?...and I thought things like calculating that is part of designing tall buildings...you think then they ignored it and put it up with tooth picks?
All tall buildings and bridges are built with margins of safety calculations just like that...and the WTC was done that way too...and that is whey the center support beams were so massive....designed to withstand the force of a big jet plane smashing into it...designed to withstand more force than they can think of.
The force of a massive section of tower collapsing on top of the rest of the tower is many times the force of the aircraft collision. Why would engineers build such a solid building that could withstand such forces? It would be cost prohibitive and would leave little room for occupants.

Unfought by humans with hoses OR automated sprinklers because the mains were cut.

here is something else you won't believe, those Mother Goose stories, they are not true either.

The inner core only holds up a certain percentage of the building's mass.

Exactly correct. Stick one end of a bent coat hanger into a camp fire sometime.

With thermite? A LOT, because you'd have to do it around the entire beam. And in some cases

Your linked video uses the term 'molten metal' and 'molten steel' interchangeably.

Of course not. Some plastic siding caught fire. Big deal. Expensive cosmetic damage.
