Beats me how that one keeps getting repeated, it's the easiest one to disprove. Watch the videos of the towers coming down, you can see fragments coming off the towers and falling faster than the main buildings did. They didn't come down at free fall speed, and it's perfectly obvious.
Sorry, near free-fall speed. With the floors detached from the central core what brought the core down? How high was the steel that can be observed as still standing at the 3:00 mark?

With the rest of the building already below this part should it not be on top of the pile?

What is the problem with the explanation (for the time-line) given on this well visited site?
9-11 Research: Speed of Fall

At 2:06 the entire building had to be below the rising dust plume that is expanding laterally. There is also a column of dust rising at great speed behind that first cloud, from which comes streamers of dust indicating a heavy object is headed back down after being propelled up quite some distance.

How far off free-fall speed is WTC7?

You're trying to argue, or at least I think you are, that it was a controlled demolition. If it were, surely the core wouldn't have been standing, breaking it up would have been a key part of the demolition, nor would the collapse have begun at the level where the planes impacted. It's impossible to tell what's going on in that cloud of dust and smoke, it appears to be about 40 stories high, but it seems reasonable to me that millions of tons of steel and concrete piling up unevenly around the bottom third of the core would knock it over. There's no way of knowing what else was standing at the time and could have fallen on top of it, it's all obscured by smoke and dust. Nor is it possible to establish a precise timeline of how long the collapse took, it's not visible. Seismic signatures suggest it was 12 to 15 seconds, it's hard to be any more precise than that. WTC7 began to collapse at the north side, where it had been heavily damaged by debris from the big towers, and leaned a fair bit during its fall, much of its debris ended up piled up against the side of another building, WTC6 I think, if my memory's correct.

I'm not going to bother looking up the details and arguing any more. There's no way any of those building collapses were controlled demolitions, they don't look the least bit that way. This paranoid conspiracy theory stuff is just stupid.

The need to believe in the conspiracy comes from the same human need as religion. People have to believe that there is a reason they can grasp for bad things that happen. No rain this summer? It's because you didn't sacrifice a goat at the spring equinox. WTC hit by planes? It's not because of some terrorist, it's an inside job by our own gov't.

It's the same human need.

LOL When you are digging into some subject/issue it is investigative work, all the ones who have spent time investigation the minute details of the 3 buildings coming down are just crack-pots. Your arrogance seems to have reached new levels Dex.

And what do you call the need to post in a thread that basically says...nothing. Sacrifice???
You guys want to believe the American Gov never lies (when there is blatant proof that it does) then so be it. I think that alone would prohibit you from saying anybody is stupid when their views conflict with yours. Even the lies they have been caught red-handed telling carries no penalty at all, that is totally stupid by itself, it is just asking for more and bigger lies.

It's not investigative work. If it was, you would accept any and all evidence. You discount that which you do not wish to accept.

This is really where you fail miserably. Not believing in your wild conspiracy theories and silly scientific ideas DOES NOT equate with believing the American government (or any other government) never lies. You have shown that your ability to think logically is so badly warped that any notion that you have the ability to do "investigative work" disappears in a haze of ground zero dust.

Once one floor collapsed, it's likely that the impact load caused the bottom floors to collapse. The building would not have been designed to withstand the shock load of the top 10 or so floors hitting the lower floors.
That would be a reasonable conclusion, yes.

The theory goes that the floors started to pancake, if that is the argument then what brought down that center core???
Perhaps you should read this about the architecture of the WTC towers:
The twin towers were unusual in that the outer cladding of the building actually carried a large part of the load for the structure. Each floor was suspended from the external walls, rather than the other way around, which is common in most skyscrapers where internal pillars provide the strength, and the walls merely keep the wind out. While intended to provide strength while maximizing rentable office space, this actually proved to be a lifesaving innovation.

Boy do you conspiracy theorist have it all wrong, yes there was a conspiracy but the real cover up was the evolution of magnets. Get out of the north country before they turn them on. They are almost ready.

Okay, Idiots!

Listen carefully......

Controled Demolition is dome by collapse from the bottom up.

The WTC collapsed from the top down.

No, no, because it 'fell at free fall speeds', then it fell from the bottom up, it's just that the video was doctored to make it seem like it didn't.

Perhaps I did read that and maybe even more. "Each floor was extended from the outer wall" to the 'inner core', your explanation does not specify where those spans 'began and ended', once loose from the core why would the core collapse?"
911 Links - WTC Core Construction

Under the picture with the yellow high-lights & numbers there seems to be a hole where the strongest part of the building should be. (BIG HINT)

911 Links - WTC Core Construction
In the first picture in the above link which looks stronger? the thin outer shell or the massive girders that define the stairways and elevators and such??

Perhaps because the steel was unevenly warmed by fire and hence warped, and then further bent by the rest of the collapsing? Sheeeesh. Are you being obtuse on purpose? (I hope). "Thus, the failure of the steel was due to two factors: loss of strength due to the temperature of the fire, and loss of structural integrity due to distortion of the steel from the non-uniform temperatures in the fire." - http://www.tms.org/pubs/journals/JOM/0112/Eagar/Eagar-0112.html

The diagram with the yellow bits appears to be a bit different than the picture that says "actual core".

In the first picture in the above link which looks stronger? the thin outer shell or the massive girders that define the stairways and elevators and such??
The "massive girders" were not massive. "This produced distortions in the slender structural steel, which resulted in buckling failures." -
