So Clipper how do you explain the WTC 7 collapse?
No plane impact, different design, different building....
Why were the only buildings to collapse owned by larry silverstein?
Why did buildings that had more damage and were closer to WTC 1&2 not collapse?
How the weight of 15 odd floors compromise 95 undamaged floors bellow them?
Why did the top of WTC 2 start to tip over and then have the rest of the building collapse under it? Why did it not continue it's path as you would expect?
What cause the concrete to turn into dust?
Why were the aircraft involved only 20% loaded when all other planes that day were 90 to 95% loaded?
Just some stuff to think about...

Well, it wasn't the weight of 15 floors exactly, you had about 30 floors below it that were full of jet fuel. In the second hit, the plane was 10-20 floors lower than the first hit. 24,000 gallons of jet fuel... think of that in terms of volume. You can see that there was quite the explosion when each plane hit. So already you have a few things occuring, a comprimise of structural integrity from the impact, the explosion of from both the impact and the fuel that lit off on impact, followed by what's left of the 24,000 gallon of jet fuel. which will then pour down every available nook and cranny.
The building is supported by a network of steel beams, which support it both through sheel physical strength and geometry. Upon impact both features are now comprimised.
Then, give that jet fuel 2 hours to work on the core of the building for 30-40 floors below. You can see that there is a huge blaze all through the building. Once the engineering that holds the building together is comprimised, it's only a matter of time.
The 2nd tower tipped due to the location of the hit being lower than the first one, but in this case again, the core of the tower is what starts to collapse. As the core started to give, the top of the tower just leaned the way that had the least support. Since there was more weight up top, it actually had a chance to tip a little as the core started to buckle.

I find building 7 suspicious. I find many things about 9/11 suspicious. I think a conspiracy is likely, but planting explosives in the twin towers is implausable in my opinion. A conspiracy works when as few people as possible know and you don't get caught.
These explosions are a red-herring. The building was ALREADY collapsing at that point from the top down, so they were too late anyway. Fuel, gas, electrics, falling burning debris and many other things could have caused those "explosions."
As for Silverstein. No surprise the WTC was a target. Like the Pentagon and the Whitehouse, it is a symbol of America. However, maybe if the Whitehouse was hit, that would be just a little too inconvenient for Bush.
I don't believe that if Silverstein was in on a conspiracy he would order the NYFD to "pull" the building as in bring it down. Are we supposed to believe they were in on the conspiracy? They lost many men that day. I also do not believe he would freely admit it to the media.
However, I am very open minded to Building 7 being brought down by explosives, but not the twin towers. But I don't see anything strange about the towers collapsing. The tilt of the top of tower 2 was due to it being so undermined on one side and then gravity did the rest straight down.
I think Bush helps Bin Laden and Bin Laden helps Bush (even if Bin Laden is now a fabrication).

The more I learn about the twin towers construction style which was unique for the time (maybe not so much today...), I am increasingly believing that demo of some sort had to happen to bring the buildings down cleanly.
The outer shell was made to be literally self upporting because it was the main part of the building taking the wind load that such a hugh building would take.
The outer wall was attached to the floors via steel clips which could easily shear if pressures increased but of course I don't know the overstrength levels engineered into the components.
The floors could have collapsed but not the internal column system nor the outside shell just from the fires as we have been told.
What I am saying is that several floors of the building have collapsed within the super structure while most of the building would remain standing.
Last time I checked concrete was not the best fuel for a fire and the towers did have a lot of concrete in them due to the style of construction used.

Without floors transfering the nessessay lateral stability from the exterior walls, what would prevent the core columns from folding over?

For the outer columns to buckle, significant force would've had to have been applied one way or another to move them out of place. It isn't a matter of what was stopping them from being moved, but what could've moved them in the first place.

The core structures had their own lateral stability. It wasn't as great as what the exteriors were designed to carry from great wind, but we have structural engineers on this board who have posted before explaining how we can tell that the core structures had their own lateral stability regardless of the outer columns. You've seen these posts before.
Are you a structural engineer?
Or a hypocrite?

All columns will buckle if sufficient loads placed on them.
What would happen if one of those floor slabs were to fail so that it was no longer providing lateral support for that column?
The length between the pinning connections will double.

Thus the core walls did not have any lateral stability.
