Then you really haven't been looking. There are plenty of people (mostly engineers who know what molten metal looks like) who reported them. There are photos of steel being pulled out that is glowing red hot.

So, basically you're saying that just because some renovations were going on that the buildings couldn't have been undergoing other "suspicious" activity?

The 911 Truth movement i feel should concentrate on getting the facts about a few things:
1. Why did Bush wait over 450 days to investigate
2. Why was the budget so tiny (in comparison to the Clinton blow job, and the Shuttle Colubia investigation)
3. Why was kissinger asked to be the chairman?
4. And why did he resign only after beign questioned by the Jersey 4.
5. Oh...and WHY did he refuse to be questioned unless Cheney was present?
Again... .great job getting the truth and the facts out there!

I believe the term is telescoping. It is real simple the cores can't. People keep wanting to treat the towers as a solid structure. They were not. They were an assembly of millions of parts. They failed when the joints were over loaded.

No one has ever shown that the towers were ever overloaded before they began to collapse. Everything else in your post aside, we have never seen a reasonable amount of perimeter buckling pre-collapse for either building. If what NIST suggests is true, then simply buckling a handful of columns per floor is apparently enough to make a whole floor's worth of trusses fail globally, instantly. That's for WTC1. For WTC2, there was a tilt, as in angular momentum, that was then lost to the air for reasons never explained to us, to allow the building to fall straight down.
Once the global collapse begins, it seems like people coming from a structural background all throw their hands up and claim the rest was inevitable, no matter what "the rest" entails. The collapses did not slow down, despite thickening structure towards the base, and despite the majority of the mass of each floor being chucked right out of the towers' footprints. Unless you believe the WTC collapses were free energy machines just because overloading = any failure is justified, the collapse waves should have at least slowed down.

Actually they should have (and did) speed up.
Once the section of the tower above the impact point started falling the momentum of the components started increasing along with it's Kinetic Energy.

bsbray11,
A Controlled demolition requires a lot of explosives placed in strategic areas all around the building. When and how was this explosive placed in the building without anyone knowing about it.
Second, controlled demolitions required more than just explosives. Demolition experts spend weeks inside an empty,closed down building planning an event. Many of the beams are cut through by about 90% so that the explosion only has to break a small bit of steel.
Read the post about thermite...and how it is not appropriate for cutting steel. I will look and try to find the information about how much thermite it would have taken (in was measured in tons) to take down the towers.
Yes the buildings fell FAST but,
the huge dynamic loads due to the very large momentum of the upper floors falling were so great that they smashed through the lower floors very quickly.

All of the structural and civil engineers in the world who have studied the collapse and made public statements agreeing with the NIST report.

you said mine are just "words". Isn't that all you have ?
Not ONE engineer has come out against what the NIST report.

I am by no means saying that all or any members here act like this, but I have seen this behavior on other boards, and presented on sites like prisonplanet.
That 9-11 scholars show on Cspan definitely fits these descriptions, with the aggresive political activism and support of the half truths and distortions of Loose Change.
While I am extremely skeptical of the demolition theories, I am open to the more plausible Let It Happen On Purpose theories.
What do the rest of you think of this?

As it collapsed the floors below the impact area the mass of those floors were added, increasing the amount of energy availible. It was quite literally like the snowball in the cartoons that just keeps getting bigger and bigger as it rolls along.

They failed when the joints were over loaded. Look at all if the pictures of the WTC debris.
Look for failures in the beams themselves. You won't find any. You will find failures in the joints. You said that you have taken some engineering classes. Have you taken Statics? Think about moments and you will have your answers. If explosives had dropped the towers, where are the sections cut by the charges? Explosives shatter metal they don't bend it.
Don't even go into Thermite.
I went to a Veteran's Day dinner last Saturday. My wife and I were seated at a table with an older couple. The man we were seated with spent 45 years working in the railroad industry. We were talking and got on the subject of the WTC collapse. He said that he got a laugh everytime someone on the news mentioned Thermite being used to cut the WTC's structure.
The railroad has used Thermite for years to weld track rails togather. They also tried to use it to cut sections of rails. This failed for as he explained it a very simple reason. Gravity. When the Thermite starts burning the Iron Oxide in it turns to liquid. When it is being used to weld rails it is this liquid that is used as a filler in the weld. However when you try to cut with Thermite, there is nothing to hold it in place long enough to heat the material that you are trying to cut. The Thermite tends to flow in the path of least resistance. You end up with a triangular section of uncut metal because the Thermite melts its way along the path of least resistance. If you put it on top of an I-beam, it would melt through the flange leaving the web of the beam intact.
Enlighten me. Where are the photos?
Define suspicious?
I am saying that there is no way that both towers could have been rigged with enough explosives to cause them to collapse the way that they did without someone finding out and leaking the information. Hell! I wish the Government could keep that kind of secret.
