9/11: What really happened

[roydamnmercer]

Did you even look at the attachments I posted? Steel loses 50 percent of its strength at 1100° F. Building fires generate temperatures of 1100° F. On a normal day the twin towers would sway up to 12". Is so hard to believe in is weakened state, the buildings collapsed.

Not to mention that at 1000° it can expand up to 10%. A twenty five foot long beam stretching out another two and a half feet would pop more than a couple rivets loose and twist off the support columns.

Everything.

I did. If the towers fell from the top down, maybe your point would have something plausable. They didn't fall over though, they collapsed demolition style from the ground 70 stories away from the fire. There is a plethora of structural engineers and demolition experts who have debunked this.

Did you even look at my attachment?!?!

Oh look, George and Dick rigged this Brazilian building to collapse too…

And if you spend a few seconds looking, you can find examples from all over the world and America…

I want to know specifically what you see that I don’t. Explain please.

Steel beams expanded 10% 7 underground basement levels and 70 stories from a burning plane?
What a reach

Angled cut, molten spall (over 2000 degree required) 6 stories below ground level.

you said it 'steel melts at 2700 degrees ......... The films of towers say it all/show it all.... If look at the films you will see molten steel pouring off the Floors .........days of old; when the Empire state building was hit, the old prop plane had 315 octane aviation (burns much hotter) fuel on board and the building was repaired.......

Perhaps the construction materials and design differences between the Empire State Building and the Twin Towers, not to mention the size of the aircraft (as well as fuel capacity and airspeed), contributed to the different outcomes.

And please, don't label me a know it all. I just search the web when i have questions. I knew none of this before i searched for it.

It’s like vertical dominoes. The top stories collapse due to weakened support structure. The shock load of one floor collapsing upon the next intensifies exponentially all the way down. Even floors with no fire damage (even though fuel and fire were burning all the way down through elevator shafts which were located in the center support structure) cannot support the shock load of all the floors above pancaking down one on top of another.

You could bring 100k gallons and it won't change. Average house fire struggles to reach 1800°f

2700 degrees is an absurd temp in open environment. The pic I posted is cut, not bent or streched
