Electron microscope analysis of steel spheres from WTC site

[kerowo]

So when the Discovery Channel (America's Scientific Channel of Record) said the impact from the jets knocked off the fire retardant and the av-gas heated the steel enough for it to sag and pull away from the exterior walls trasfering the load they had been carrying to the structure below resulting in the buildings pancaking you say what?

To quote it more exactly, the government report says 'and global collapse ensued'. That's it; it describes nothing and it explains nothing. Notice that I am calling for a sequential mechanism.

How much did a WTC floor weigh?
What is the impulse/momentum generated by a block this weight dropping 3 meters?
How does this compare to the typical load on the steel structure from say the 50 floors it would normally have to support?

Answer these three questions (it's very, very simple physics) and you'll realize that global collapse is indeed inevitable once the first floor goes.

There are legitimate questions to be raised about the collapse but it seems like you've picked the worst possible points. [img]/images/graemlins/blush.gif[/img]

You have not described a sequential mechanism, or pointed to a source that does describe it.

It would be very interesting if you would actually give that a try. Then we can see if that mechanism matches with what we see on the videotapes and the photographs, with the speed of the collapse, things like amount of thick dust, and so on.

NIST has not dared to do it.

Here's the sequential mechanism. One floor collapses 70 or 80 floors up, The entire weight of the part of the building above that floor falls into the floor below, then the floor below that one, etc. until the whole thing is a pile of rubble on the ground.

Regarding the claim that the fire couldn't have caused the collapse: Remember the gas truck that burned under the bridge in Oakland a few weeds ago, resulting in the collapse of the (at least partly steel) bridge? The people on these silly-ass web sites telling you that the fire couldn't cause the building to collapse (especially after it was damaged by the impact of the plane) are full of crap. No, I didn't read the site your linked to, and I'm going to. However, on similar sites that I have read, it usually takes only a few paragraphs to tell that they have no clue what they are talking about. They will spout a lot of gobbledygook that looks impressive to people lacking in scientific training and critical thinking skills, but which is obviously [censored] to anybody who has them.

The world trade center collapsed because two planes hit the towers and caught fire inside them. Probability 99.9999999%.

Was there a cover up? Most likely. Cover up is the Bush administration's natural mode of operation, even when there is nothing to cover up, or (most commonly) nothing to cover up except their incompetence, which they inevitably fail to cover up, because they're too incompetent to conduct a cover up. See U.S. attorney firings: Only the Bush administration could turn something they had every right to do into a scandal. All they had to say is "We fired them because we didn't like them". Instead, they had Gonzalez claiming he knew nothing about why his own employees were fired, and changed their story 7 or 8 times. Now, do you really think think Larry, Moe and Curly -- Oops! I mean Dubbaya, Dick and Rummy, were smart enough to stage a fake terrorist attack and get away with it? I don't

Let me stop you there, as I think this doesn't match with the video footage. The video footage shows that the part above the impact zone collapses in on itself whereby the impact zone 'stays put'. Only after the part above the impact zone has collapsed halfway to 2/3rds does the whole thing start moving down from the impact zone.

OMG a month ago no one cared about this and you brought it back? What did you just get a refill on your kook pills?

Why do you assume the collapse must initiate at the impact point? It was a huge fire. The collapse begins in a region that is on fire. Is that not strongly suggestive of fire-induced collapse? Where on that video do you define as the impact point, anyway?

The portion of the building below the distinct fire line clearly stays intact longer, until it is overwhelmed by the falling weight. This is not consistent with sequential explosives going off all the way down. It is consistent with pancaking.

Have you dropped the claim that explosives went off all the way down, and are you now saying explosives only initiated the pancaking that destroyed the building? We need a detailed sequential explanation FROM YOU.

Remember also that the outside shell of the building is structural (load bearing). So a collapse can begin inside the building, with the outer shell lagging behind because it is stronger. That can throw off our visual interpretation.

You've picked one tiny thing to respond to, while people carefully made many points the month or so ago when you were last active.

I don't understand how what he described isn't a sequential mechanism. First floor collapses triggering the next floor to collapse, so on and so forth until all floors have collapsed.
