I still say after the bombings in the parking garge.93 bombingThey sat down had a meeting and decide the destruction created by one of these buildings tipping from an explosion was to much to dill with in the aftermath and the loss of life and property from the surrounding buildings were to high. So they devised a way to limit the damage by placing explosives perminently in the buildings in case of emergency. On 911 emergecy was declared and the owner of the building in his own words said "pull it" meaning blow the structure so there would be less chance of tipping buildings and a controlled in its own footprint collapse. Im not saying they were part of 911 just they had a secret emergency plan for less destruction. I think even them involed with this emergency planning never had any idea how much chaos and destruction would be involed but couldn't imagine how much more there could be with a tipping building collapsing on neigboring buildings the domino effect was to scary to allow.
When completed, it was the world's tallest marble-clad building, being sheathed entirely with 43,000 slabs of Italian Carrara marble. The marble used was thinner than previously attempted in cladding a building; this quickly proved to be a mistake. In 1974, just a year after completion, one of the marble slabs detached from the façade and penetrated the roof of the nearby Prudential Center Annex. Further inspection found numerous cracks & bowing in the marble cladding of the building. To alleviate the problem, stainless steel straps were added to hold the marble in place.[3] Later, from 1990 to 1992, the entire building was refaced with Mount Airy white granite at an estimated cost of over $80 million.[2][4] (Amoco was reticent to divulge the actual amount, but it was well over half the original price of the building, without adjustment for inflation.) The discarded marble was crushed and used as landscaping decoration at Amoco's refinery in Whiting, Indiana.[2]
It is believed that 90 West's heavy building materials and extensive use of terra cotta inside and out helped serve as fireproofing and protected it from further damage and collapse, as opposed to the more modern skyscraper at 7 World Trade Center, which suffered similar damage and collapsed later that day.
The building experienced major damage in the September 11, 2001 attacks. Its thick masonry exterior and use of masonry to protect steel columns and structural elements helped the building withstand the attacks. Restoration of the building after the attacks took three years, at a cost of $1.4 billion.

I'll start sending memos out to CD companies and let them know they can stop wasting so much time and money on explosives and paying large teams for months planting those explosives because fire can do what explosives can do for a fraction of the cost and a fraction of the time:

The plane impact caused damage to structure but not enough to cause it to fail.

This started the domino effect that caused the buildings to collapse.

Do to its lite weight construction instead of floor joists resting on cement like the building you think was designed the same is.

Couldn't trust radio controls because in demolitions timing is everything.Not to mention the fact that there was already so many radio signals in that building as to make it useless to try remote detonation. So we would have to run a wire from these to a secure location.

These explosions that people think they saw when the building collapsed is called explosive decompression trapped air escaping thats why i laugh when people try to show explosions while the building is already collapsing.

Now before a demolition your going to hear something like the forth of July lots of very loud bangs in succession.Ive watched videos and guess what there not there. hmm thats strange the building started to collapse before the explosions went off thats odd isn't it?
Gregg Brady, 9110184
I heard 3 loud explosions. I look up and the north tower is coming down now.
Frank Campagna, 9110224
You see 3 explosions and then the whole thing (north tower) coming
down.
Craig Carlsen, 9110505
I guess about three minutes later you just heard explosions coming from building two, the south tower. It seemed like it took forever, but there were about ten explosions.

It seemed like on television they blow up these buildings. It seemed like it was going all the way around like a belt, all these explosions...
Karin Deshore, 9110192
Somewhere around the middle of the (north tower), there was this orange and red flash coming out. Initially it was just one flash. Then this flash just kept popping all the way around the building and that building had started to explode. The popping sound, and with each popping sound it was initially an orange and then red flash came out of the building and then it would just go all around the building on both sides as far as I could see. These popping sounds and the explosions were getting bigger, going both up and down and then all around the building.
Stephen Gregory, 9110008
I thought that when I looked in the direction of the Trade Center before it came down, before No. 2 came down, that I saw low-level flashes. In my conversation with Lieutenant Evangelista, never mentioning this to him, he questioned me and asked me if I saw low-level flashes in front of the building, and I agreed with him because I thought -- at that time I didn't know what it was. I mean, it could have been as a result of the building collapsing, things exploding, but I saw a flash flash flash and then it looked like the building came down.
Q. Was that on the lower level of the building or up where the fire was?
A. No, the lower level of the building. You know like when they demolish a building, how when they blow up a building, when it falls down? That's what I thought I saw.
Q. On the television pictures it appeared as well, before the first collapse, that there was an explosion up on the upper floors.
A. I know about the explosion on the upper floors. This was like eye level. I didn't have to go like this. Because I was looking this way. I'm not going to say it was on the first floor or the second floor, but somewhere in that area I saw to me what appeared to be flashes.

This is the reason in demolitions you expose the beams
Originally posted by dragonridr
id say its safe to assume explosives weren't used.
Originally posted by dragonridr
i will say the facts are contradictory to the assertion that there was demolitions involved.

Now you can assume i don't know what I'm talking about thats fine don't really care what you believe

Your diatribe accusing a long-time ATS member of being a "troll" seems a bit dodgy.
If it had been free fall, with no restraint, the collapse would have only taken eight seconds and would have impacted at 300 km/h. It has been suggested that it was fortunate that the WTC did not tip over onto other buildings surrounding the area. There are several points that should be made. First, the building is not solid; it is 95 percent air and, hence, can implode onto itself. Second, there is no lateral load, even the impact of a speeding aircraft, which is sufficient to move the center of gravity one hundred feet to the side such that it is not within the base footprint of the structure. Third, given the near free-fall collapse, there was insufficient time for portions to attain significant lateral velocity. To summarize all of these points, a 500,000 t structure has too much inertia to fall in any direction other than nearly straight down.
1.) We have plumes, which I posted an image above, that have only ever been seen in controlled demolitions.
2.) We have numerous documented witnesses, civillian and first responder, to the sounds of the detonation sequence and a multitude of flashes going up, down and around the building with popping or exploding sounds as is seen in most controlled demolitions.
3.) Many controlled demolitions start in the basement or ground levels. We have numerous documented witnesses to the many explosions that destroyed the machine shop, parking garage, elevators and lobby which is also consistent with controlled demolitions that start in the lower levels.
4.) Then we have the collapse physics where the buildings collapsed through themselves, i.e., through the greatest resistance without slowing down. Indicating that the structure below was weakened to allow the building to collapse through itself, just like most other controlled demolitions.
I posted alot of information above and either you didn't read it all, or you don't care/can't refute some of it.
Care to explain how a 50-ton hydraulic brake press and an entire machine shop can be destroyed...
...a 300-pound steel and concrete fire door crumpled up and laying on the ground, parking garage destroyed, lobby destroyed, all without explosives?
