Nothing other than explosives can make molten pools like that.
Funny, I melt aluminum with a torch all the time. :thinking:
The Towers fell in 12 seconds from start of the top going down to the ground, Thats Free Fall Speed.
When you have more than ten stories (plus more and more) of a building crushing everything below it, it's going to fall quickly.
Neglecting air resistance, something 417m in the air (the roof of the WTC) takes 9.2s to fall. Your 12 seconds is not freefall speed. Throw air resistance in and the number rises, and throw building resistance in and it rises to your 12 seconds. Did you calculate "free fall" speed, or did you source the math from Loose Change?
d = v0*t + 0.5at^2
Also, the core of the building collapsed more slowly if you do a bit of deeper reading. The outer parts of the floor had less core support and were more prone to being crushed quickly by the rest of the building collapsing. I'll see about sourcing that material...
They both had 70+ stories of perfect intact structure with steel vertical columns, What knocked the columns down?
Each floor was crushed straight down in turn by the colossal amount of weight above it. Nothing was "knocked down."
In your theory they would be sticking up some?
You don't have a full comprehension of the forces in play here.
A Falling Object will take the path of least resistance it would topple or Bend if it weaken like you claim and a mass would be left.
Newton would fail you out of physics. Once the colossal chunk of the building begins moving downward, it's going to need a very, very serious lateral force to make it topple over rather than collapse straight down. The only thing the rest of the building exerted was normal force - an opposing force straight up.
And how did 110 stories of Solid Concert and Steel turn into 3-4 story pile? What Turned the concrete into Powder?
Are you saying that the matter simply disappeared? That is a violation of the laws of thermodynamics, Mr. Krogith.
Are you saying that a bomb and subsequent collapse could yield a "3-4 story" (don't remember if those are the right numbers) pile of rubble, but not a plane crash and subsequent collapse?
Huge forces like building collapses turn concrete into powder.
And They were designed to take a bigger airplane to each tower.
I've not seen much material concerning this, please show me your reputable source.
