To those of you who think planes brought down buildings on 911

I get that you buy all that. And you might convince a lot of people to believe it also. There might even be sound engineering science to back it up. (but please supply links to show you at least looked into it.

But building 7. Please explain to me how this happened. I don't understand the science or reasoning. Could you please send me some links that explain the science to cause that building to fall at free fall speed?

1. I always heard that Mr Silverstein was going broke on the lease

and did what real estate people underwater do at times. They used to buy slums and after a period of time torch them to get the insurance and rebuild as condos.

But those are my opinions.

4. Silverstein: "pull it!"

[Ned_Devine]

2. 14 years later and still no answers

Yet they make fun of us for being 9/11 "truthers"

[LiberalArkie]

9. If a person can accept that landlords used to torch slum buildings in

New York (even with people in them) for insurance money, why can't a person accept that maybe the landlord of WTC did the same thing.

[LiberalArkie]

3. But Wiki has an interesting theory presented. I like the last sentence.

Snip

On September 11, 2001, 7 WTC was damaged by debris when the nearby North Tower of the World Trade Center collapsed. The debris also ignited fires, which continued to burn throughout the afternoon on lower floors of the building. The building's internal fire suppression system lacked water pressure to fight the fires, and the building collapsed completely at 5:21:10 pm, according to FEMA,[6] while the 2008 NIST study placed the final collapse time at 5:20:52 pm.[7] The collapse began when a critical internal column buckled and triggered structural failure throughout, which was first visible from the exterior with the crumbling of a rooftop penthouse structure at 5:20:33 pm. The collapse made the old 7 World Trade Center the first tall building known to have collapsed primarily due to uncontrolled fires,[8] and the only steel skyscraper in the world to have collapsed due to fire.[9]

6. And amazinly

in it's own footprint!

What are the odds of that!

[63splitwindow]

5. Alternatively...

an intricate conspiracy where all co-conspirators have kept silent?

I'll just accept that an uncontrolled fire finally caused a complete compromise of structural integrity and down she came.

[PearliePoo2]

7. Well...that certainly is impressive.

Definitely in the category of things that make you go...hmmmmm?

[xocet]

12. It is more like things that make you go - "Really...not this again!" n/t

[Adenoid_Hynkel]

8. -sigh- Give it a rest, Alex Jones

This tinfoil junk science is every bit as dumb as birtherism.

[Pharaoh]

11. then answer the questions

Links? Data?

[xocet]

10. Please tell me what free fall speed means to you. n/t

[Pharaoh]

13. watch the video

In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it and moves along a geodesic. The present article only concerns itself with free fall in the Newtonian domain.

[xocet]

16. That is cut&paste, but it does not answer the question. What does "free fall speed" mean to you?n/t

[Pharaoh]

17. no resistance

which means explosives must have been involved

[Quixote1818]

18. The core of the building had already collapsed

So it's quite easy for the shell to collapse at close to free-fall once there is nothing in the middle holding it up. But why demolish a building that has already burned for 7 hours?

[Pharaoh]

19. how did the core collapse?

not by fire.

[Quixote1818]

14. Here are a couple

[louis-t]

15. What speed would you expect a building to fall?

Slow motion?

[OldRedneck]

20. You need a new hat

Wear it shiny side out.

You do know the 1969 moon landing was fake??

[Pharaoh]

22. I never said the moon landing was fake

what thread are you on?

[Politicalboi]

21. Their sound engineering is to show the NIST video

With the core columns still standing without their pancake stack of debris to explain their "pancake theory". Planes cannot penetrate steel and concrete at sea level speeds without breaking up and leaving some debris at crash point on the ground.
