Donald Trump is still a citizen.
DJT happens to be wrong about the design of the building being “stronger” than the standard way sky scrapers had been built before the WTC towers - with the most important structural support being the side walls themselves; and none have been built that way sense.
Osama was a structural engineer by education and trade before he started leading Al Queda. With his fathers firm he had overseen the building of many major buildings for the Suadis.
I think someone managed to get him plans for the WTC towers.
With most of the main support for the towers resident in the sides, in the vertical walls you saw when looking at the building, those walls had to support floors that had no vertical columns until you got to the core around the elevator, air, and stairwell shafts. To distribute that weight they used trusses to carry the load to the side walls.
THAT was where the buildings failed. In the damage and the intense heat key trusses began to separate from the side walls at certain points, no longer supporting the load at those points the load was added to the load of other trusses. Then the truss system had three problems - the damage, the intense heat, and trusses no longer connected to a sidewall or to more than one sidewall together with trusses and their connects at the sidewalls having to makeup for loads damaged & disconnected trusses no longer were carrying.
What you see in the videos is the pancaking affect as floors above fail, adding their weight downward to floors below, and as more failures happen the rate of failure - the accumulation of the load, becomes more inevitable at every stage.
Someone figured out that the truss system and its connections to the outer walls could be a weak link, IF somehow, at some very high point you could damage that system enough to start a cascading problem of load shifting due to failures of the trusses where they connect to the side walls. That someone was a structural engineer - Osama Bin Laden.
As to Trumps comment that it seemed to him that the planes “impossibly” went nearly through the buildings, with their noses extended out the opposite side, he forgot that those floors had no vertical columns to get in the way (until the core), and while the core structure may have taken out a wing, that left the fuselage continuing through the floor. In fact both wings were probably destroyed (sheered off the fuselage) on impact with the vertical columns on the side wall they immediately hit.
Didn’t the buildings come down because the steel was heated to the point that it softened, and the hot are failed and it and the stories above it fell straight down and collapsed the lower stories?
The planes themselves didn’t have to go into the building (but they did). The problem causer was the fuel that flowed into the building and ignited.
Is Trutherism still banned on FR?
Perhaps this is another reason why the DS really hates him. He’s pretty independent. And he a builder.
Trump was not even on my radar in those days. Oh, try and find this on the leftists spider web...
