Because the 767s were traveling at high speeds, were somewhat larger than 707s and each carried about 80 tons of jet fuel, Robertson said, the energy that was absorbed by the impact was not less than three- times, and probably as much as six-times greater than the impact we had considered.
The 707 flies faster than a 767, and being that they are roughly weigh about the same, the 707 would do more damage due to its higher kinetic energy.
BTW, those 767's were carrying only about 10,000 gallons of fuel, less than half their total capacity. 10,000 gallons works out to 31,000 kilograms or 31 metric tons, not 80 as you claim.
Get your facts straight boy.
The impact would be less than half of the design expectation, due to the fuel load and the velocity being less than a 707's.

The WTC had a concrete and tapered steel beam [thick at pottom thin on top] core with elevator shafts in their midst and were not "solid", btw.
Do you even look at the images you post? The image indicates a reinforced steel core. Are you blind as well as being dumb?
Here's an image of the WTC under construction. Note that the steel core is considerably more massive than depicted in the image you posted.

So do you finally admit that it was impossible for the tilted top of the tower as I had shown to have dropped straight down when it was already in the process of tumbling to its side?
And do you admit that it was impossible for the towers to have collapsed as fast as they did?

Do you see where I'm going with this? If the top of the tower tilted to its side then dropped straight down, the only explanation would be that the core was intact but bent and that the top of the tower slid down the core. So if the core was intact, where IS IT? It simply vanished, as if it wasn't even there.
There are some videos which show a "spire" like core structure reaching up to mid level of the tower, then simply vaporizing 20 seconds or so afterwards.
Hmmm. What do you make of that? Did you find any NIST data that speaks about that topic?
And BTW, if the top of the tower slid down the core, how could it have fallen at virtual free fall speed where there would have been tremendous friction involved slowing down its descent? In addition to the time required to overcome the resistance to the steel core, what about the time required to smash the steel and concrete of each of the 100 floors below it? It did all that in about a second, subtracting the time it would have taken for it to fall through thin air.
C'mon Mr. Wizard, give us some physics here.

Generally speaking, blasters will explode the major support columns on the lower floors first and then a few upper stories. In a 20-story building, for example, the blasters might blow the columns on the first and second floor, as well as the 12th and 15th floors. In most cases, blowing the support structures on the lower floors is sufficient for collapsing the building, but loading columns on upper floors helps break the building material into smaller pieces as it falls. This makes for easier clean-up following the blast.
So for WTC7, it would be fairly easy to do this.
Also, in the link I provided, look at the image that shows where explosives are generally put to bring down a building. Maybe 9 different places, treating each building as a group of 9 different towers, would need explosives. Now, that seems extremely easy to get away with. Something the U.S. government is more than capable of planning and acting on.
A brief summary of some outstanding and unanswered points of fact surrounding the WTC collapses.
* The engineers who designed the building designed it to withstand impact by planes and fire. To be able to take multiple impacts from similarly sized aircraft as the 767--Like a window screen being poked with a pencil, it would do nothing to the integrity of the structure.
* Never before in history has a steel framed skyscraper been brought down from fire, yet on 9/11, by coincidence, three such buildings collapsed in under ten seconds each.
* Building 7, which was not structurally damaged by aircraft, came down in a manner that matches the signature demolition model, complete with triggering squibs (outward explosions of support structures preceding the falling mass), and falling into its footprint. Slow motion video footage highlights these features.
* Larry Silverstein, the owner of the WTC complex, admitted on a September 2002 PBS documentary, "America Rebuilds" that he and the NYFD decided to 'pull' WTC 7 on the day of the attack. The word 'pull' is industry jargon for taking a building down with explosives. Larry Silverstein, WTC 7, and the 9/11 Demolition
* Explosions and warnings to get back from WTC 7, "it is about to come down." WTC7 - Incriminating evidence Listen, five seconds in, you can clearly hear the BOMBS going off. "Did you hear that?", "Keep your eye on that building, that things coming down ....", "The building about to blow up ... move it back", "Alright guys .. ", "Move it back because the building is about to blow up ...", Firefighters: Explosion, Fireman: Bomb In The Building, We think there is going to be another explosion, Fireman: Boom, boom, boom
* How did the 9/11 Commission Official Report deal with the WTC7 collapse? They omitted it entirely. Not one mention of it.
* Towers 1 and 2 also fell in a manner consistent with demolition, and had numerous visible squibs preceding the falling mass. Bear in mind that a "tidy" and "safe" fall would not necessarily be the objective of individuals pulling off such a thing.
* Rate of speed of the fall is near that of free-fall, which contradicts the pancake model in which a delay must be expected due to conservation of momentum one of the foundational Laws of Physics.
* The fine powder into which the building was converted during the collapse is consistent with the demolition model and its associated explosives. There would have been some pulverization in the pancake model, but not to the extent seen in this case.
* Molten steel in the wreckage, weeks after the collapse, is consistent with military-grade demolition charges, in which chemicals continue to react with the metal long after the initial implosion event. Molten Steel at WTC site weeks later, Thermite & The Case for Controlled Demolition
* NIST report 10/19/04: suggest that the steel was probably exposed to temperatures of only about 500F (250C), which is what one might expect from a thermodynamic analysis of the situation. "most perimeter panels (157 of 160) saw no temperature above 250C". To soften steel for the purposes of forging, normally temperatures need to be above 1100C. Newer NIST report contradicts original findings. Google search: "saw no temperature above 250c" nist
* Numerous eyewitnesses described hearing multiple explosions and popping not associated with the planes hitting the buildings.
* WTC buildings 1,2 and 7 had undergone unannounced security evacuations in the days prior to Sept. 11. A concurrent power outage disabled security cameras. Explosives-sniffing dogs were called off as part of that evacuation procedure. Marvin Bush, brother to the President, was a principal in a security company, Securacom and now named Stratesec, for the WTC center, Dulles International Airport and United Airlines
* It would only take 10 men ten trips to place the necessary explosives to bring the towers down by demolition.
* The 911 Commission report says that there were no central support columns, which is a lie. The WTC had the most robust central support columns, 47 massive steel columns, in the world at the time it was built, and was designed to be centrally supported.
* Virtually all of the steel was quickly sold to scrap dealers, trucked away, and sent to Asia to be melted down. Thus the evidence was destroyed which could have shown whether explosives had been used to slice them, contrary to laws governing removal of items from a crime scene..
* The towers were basically condemned in 1989 because of Galvanic Corrosion between the outer wall parts having aluminum in them and not electrically insulated properly when built. The cost then to bring them down was $5.6 Billion dollars. Deposition on the problem, Google search: galvanic corrosion wtc 1989 It is only corrosion on the aluminum panels on the exterior of the building. It had nothing to do with any support of the buildings only the fascia of them. The buildings were primarily supported by the 47 central columns. They took those columns out in just a very few places and with the support gone the outer walls were crushed thus throwing them outwards in 30 and 60 foot chucks. If the outer walls gave way then just that part would have fallen leaving all the rest standing.
* Mark Bingham, a passenger on Flight 93, is supposed to have called his mother and said, 'Hi, Mom, this is Mark Bingham!' His mother confirmed it was his voice, but does anyone seriously believe that Mark Bingham would have used his last name in identifying himself to his mother? See When Seeing and Hearing Isn't Believing - Voice morphing technology
* The Northwoods Document irrefutably establishes our government WOULD openly conspire to not only provoke and allow an attack (to further an already established military agenda) ...they'd actually manufacture the entire event.
* Video of Norman Mineta stating before the 911 commission about Cheney in the bunker giving orders--stand down..
* There are over 80 Senior Military, Intelligence, and Government Critics of the 9/11 Commission Report and the official story. Additionally there are over 110 Scholars listed also.

Bush-Linked Company Handled Security for the WTC, Dulles and United
by Margie Burns
George W. Bush's brother was on the board of directors of a company providing electronic security for the World Trade Center, Dulles International Airport and United Airlines, according to public records. The company was backed by an investment firm, the Kuwait-American Corp., also linked for years to the Bush family.
The security company, formerly named Securacom and now named Stratesec, is in Sterling, Va.. Its CEO, Barry McDaniel, said the company had a ``completion contract" to handle some of the security at the World Trade Center ``up to the day the buildings fell down."
It also had a three-year contract to maintain electronic security systems at Dulles Airport, according to a Dulles contracting official. Securacom/Stratesec also handled some security for United Airlines in the 1990s, according to McDaniel, but it had been completed before his arriving on the board in 1998.
McDaniel confirmed that the company has security contracts with the Department of Defense, including the U.S. Army, but did not detail the nature of the work, citing security concerns. It has an ongoing line with the General Services Administration - meaning that its bids for contracts are noncompetitive - and also did security work for the Los Alamos laboratory before 1998.
Marvin P. Bush, the president's youngest brother, was a director at Stratesec from 1993 to fiscal year 2000. But the White House has not publicly disclosed Bush connections in any of its responses to 9/11, nor has it mentioned that another Bush-linked business had done security work for the facilities attacked.
Marvin Bush joined Securacom when it was capitalized by the Kuwait-American Corporation, a private investment firm in D.C. that was the security company's major investor, sometimes holding a controlling interest. Marvin Bush has not responded to telephone calls and e-mails for comment.
KuwAm has been linked to the Bush family financially since the Gulf War. One of its principals and a member of the Kuwaiti royal family, Mishal Yousef Saud al Sabah, served on the board of Stratesec.
The managing director at KuwAm, Wirt D. Walker III, was also a principal at Stratesec, and Walker, Marvin Bush and al Sabah are listed in SEC filings as significant shareholders in both companies during that period.
Marvin Bush's last year on the board at Stratesec coincided with his first year on the board of HCC Insurance, formerly Houston Casualty Co., one of the insurance carriers for the WTC. He left the HCC board in November 2002.
But none of these connections has been looked at during the extensive investigations since 9/11. McDaniel says principals and other personnel at Stratesec have not been questioned or debriefed by the FBI or other investigators. Walker declined to answer the same question regarding KuwAm, referring to the public record.
Walker is also chairman and CEO of Aviation General, a Tulsa, Okla.-based aviation company with two subsidiaries. SEC filings also show al Sabah as a principal and shareholder in Aviation General, which was recently delisted by the Nasdaq. Stratesec was delisted by the American Stock Exchange in October 2002.
The suite in which Marvin Bush was annually re-elected, according to public records, is located in the Watergate in space leased to the Saudi government. The company now holds shareholder meetings in space leased by the Kuwaiti government there. The White House has not responded to various requests for comment.
Speaking of the Watergate, Riggs National Bank, where Saudi Princess Al-Faisal had her ``Saudi money trail" bank account, has as one of its executives Jonathan Bush, an uncle of the president. The public has not learned whether Riggs - which services 95 percent of Washington's foreign embassies - will be turning over records relating to Saudi finance.
Meanwhile, Bush has nominated William H. Donaldson to head the Securities and Exchange Commission. Donaldson, a longtime Bush family friend, was a Yale classmate of Jonathan Bush.
On the very day of the tragic space shuttle crash, the government appointed an independent investigative panel, and rightly so. Why didn't it do the same on Sept. 12, 2001?

Welcome to the "Missing Links" Website. As mastermind/creator of this site and the film "Missing Links", I, Mike Delaney want everyone to STEAL this movie and call it your own and get it out to everyone you know. This video was the sacrifice of people like myself who wanted the REAL truth about 9/11 to get out.
Thank you
Mike Delaney
Now you will discover the definitive truth about 9/11 and learn why even the most popular movies on the subject have failed to address the evidence exhaustively presented in this video. The facts will make it abundantly clear that the so-called 9/11 Truth movement has been infiltrated and is ultimately controlled by the same criminal group who masterminded the attacks. As they say, 'if you want to control the dissent you lead the dissent.' Utilizing evidence from the FBI, CIA, NSA, US Armed Forces Intelligence sectors, Foreign Intelligence organizations, local law enforcement agencies and independent investigators, Missing Links goes where no other 9/11 video has dared to.
war doesn't have answers that are logical, he has his heart felt beliefs. The government and media propaganda about 9/11 worked very well on most people.
the architects/engineers admitted that the 767 hits were outside of the parameters of their "707 scenario".
The architects who designed the World Trade Center designed it to withstand the direct impact and fuel fire of a commercial airline crash. Aaron Swirsky, one of the architects of the WTC described the collapse as "incredible" and "unbelievable." 1 Lee Robertson, the project's structural engineer said: "I designed it for a 707 to hit it. The Boeing 707 has a fuel capacity comparable to the 767." 2
A lead engineer who designed the World Trade Center Towers expressed shock that the towers collapsed after being hit by passenger jets.
"This building would have stood had a plane smashed into it," said Hyman Brown, a University of Colorado civil engineering professor and the trade center's construction manager. "But 24,000 gallons of [burning] aviation fuel melted the steel.
"Nothing is designed or will be designed to withstand that kind of fire."

China's Tallest Building Catches Fire, Does Not Collapse
World Financial Center in Shanghai miraculously defies physics
Prison Planet | August 15, 2007
Paul Joseph Watson
Shanghai's World Financial Center, the tallest building in China upon completion, defied all known physics yesterday afternoon when it caught fire but did not collapse, a modern day miracle in light of the commonly accepted premise that since 9/11, all steel buildings that suffer limited fire damage implode within two hours.
Shanghai's World Financial Center, the tallest building in China upon completion, defied all known physics yesterday afternoon when it caught fire but did not collapse
WTC1, WTC2 and WTC7 are the only steel-structure buildings ever to have collapsed (allegedly) as a result of fire. There are several cases of fires in other such buildings, none of which collapsed.
In May 1988 a fire at the Interstate Bank Building in Los Angeles destroyed four floors and damaged a fifth floor of the modern 62-story building. The fire burned for four hours. The building did not collapse. See www.iklimnet.com/hotelfires/interstatebank.html In February 1991 a fire gutted eight floors of the 38-story One Meridian Plaza building in Philadelphia, Pennsylvania. The fire burned for 18 hours. The building did not collapse. See www.sgh.com/expertise/haz...ing/meridian/meridian.htm
In October 2004 in Caracas, Venezuela, a fire in a 56-story office tower burned for more 17 hours and spread over 26 floors. Two floors collapsed, but the underlying floors did not, and the building remained standing. See www.cbsnews.com/stories/2...18/world/main649824.shtml In February 2005 there was another "towering inferno" in Taiwan. The fire burned for about an hour and a half, but the building never came close to collapsing. See www.itv.com/news/world_404914.html
caracas fire
Windsor Building burning Also in February 2005 the 32-story Windsor Building in Madrid, Spain, caught fire and burned for two days. The building was completely engulfed in flames at one point. Several top floors collapsed onto lower ones, yet the building remained standing. See news.bbc.co.uk/2/hi/europe/4263667.stm
See also Christopher Bollyn's 9/11 and the Windsor Tower Fire.
Windsor Building still standing
It is not well-known that WTC1 itself survived a serious fire in 1975. It started on the 11th floor and spread to six other floors, burning for three hours. For more details see The World Trade Center Fires (Not So Hot eh?). How come WTC1 survived a 3-hour fire in 1975 but completely collapsed as the (alleged) result of a fire lasting less than two hours on 9/11?
In response to this question one reader wrote:
I would submit that none of the other buildings were hit by a heavy aircraft moving at 500 miles per hour, which sheared off many beams, support structures, etc. The shock to the tower must have been tremendous! Isn't this obvious?
It may be "obvious" that a heavy plane hitting a skyscraper would deliver a "tremendous" shock, but it doesn't follow that the building must therefore collapse. In 1945 the Empire State Building was hit by a B-25 bomber, but it was still standing last time I saw it. "Ah yes, but it was the impact plus the fires!" Well, when the B-25 hit the Empire State Building "its fuel tanks were reported to have exploded, engulfing the 79th floor in flames", as we read at Empire State Building Withstood Airplane Impact.
"Ah, but none of the buildings mentioned above were struck by a 390,000 pound aircraft traveling at 350+ m.p.h." Well, each of the Twin Towers was still standing 50 minutes after being hit, so it was not the impacts which caused them to collapse. "Ah, but the intense heat of the burning jet fuel!" Actually, according to NIST's chief WTC-investigator the jet fuel burnt itself out in less than ten minutes. Don't believe it? Read through Reply to Popular Mechanics re 9/11: Claim #6. Then go to the top and read it all. Then follow the links to other articles on this website showing that the official story is bogus. Then follow the links to the many other websites which demonstrate that 9/11 was an inside job. Too busy? Oh, well, then, if you don't care to know what really happened on 9/11 ...
What you have heard ever since 9/11 on network TV and in the mainstream media such as the New York Times and all the other corporate-controlled newspapers is simply the official story, repeated over and over, on the assumption that if a lie is repeated often enough then people will believe it. Especially if it is a big lie. The idea that elements of the US government were responsible for planning and carrying out acts which killed about 3000 people is so outrageous that most people (most Americans, at least) reject it reflexively. But it is precisely because it is so outrageous that the perps assumed that no-one except a few fringe thinkers would ever take it seriously, and that they would get away with this act of mass murder. What they didn't count on was that thousands of websites would minutely examine the evidence available (such evidence as was left, mainly photographic, after New York Mayor Giuliani ordered every scrap of physical evidence removed from the WTC site as quickly as possible, with nothing but a token forensic examination, and shipped overseas to be melted down in blast furnaces).
An examination of the evidence which remains leads inexorably to the conclusion that 9/11 was an inside job, perpetrated by elements within the US government (probably going back before Bush came to power in 2001) in order to justify US military aggression against any country which stands in the way of its aim of global economic, financial and political domination. Maybe you think that the deaths of 100,000 Iraqis, the bombing of any country that the US chooses to bomb, thousands of deaths and injuries among US soldiers, and the contempt of all other countries for the US, are worth it to maintain US global domination; but what about the mass murder of around 3000 people, mostly US citizens, in New York City on 9/11? A small price to pay? This website presents much of the evidence that elements within the US government carried out this atrocity, and there are also many other websites which do so. If you can read then there is now no excuse to plead ignorance.

Windsor Building burning Also in February 2005 the 32-story Windsor Building in Madrid, Spain, caught fire and burned for two days. The building was completely engulfed in flames at one point. Several top floors collapsed onto lower ones, yet the building remained standing.
It collapsed from an out of control fire weakening one of the main support beams.
You believe that a 110 story building can fall to the earth at the same rate as it would if it fell through thin air, neglecting the fact that it had to crash through at least 80 stories of undamaged steel and concrete, and that 19 Arab hijackers that "hated us for our freedom", of whom at least 5 are still alive, commandeered four US airliners and flew precision attacks against this Nation, and evaded US air defences for over an hour?
the planes were just to hide and obfuscate what really caused the towers to collapse....
agreed.

It actually collaped to the north and east and took out a good snick of Fitterman Hall which stands about 30 yards from me and was damaged substantially on its southern face from 7's collapse.
It all but fell right into its footprint...you are talking about fractions rather than yards of difference between what "should have" happened as opposed to what actually happened.
1. If the World Trade Center (WTC) towers were designed to withstand multiple impacts by Boeing 707 aircraft, why did the impact of individual 767s cause so much damage?
2. Why did NIST not consider a controlled demolition hypothesis with matching computer modeling and explanation as it did for the pancake theory hypothesis? A key critique of NISTs work lies in the complete lack of analysis supporting a progressive collapse after the point of collapse initiation and the lack of consideration given to a controlled demolition hypothesis.
3. How could the WTC towers have collapsed without a controlled demolition since no steel-frame, high-rise buildings have ever before or since been brought down due to fires? Temperatures due to fire don't get hot enough for buildings to collapse.
4. Weren't the puffs of smoke that were seen, as the collapse of each WTC tower starts, evidence of controlled demolition explosions?
5. Why were two distinct spikesone for each towerseen in seismic records before the towers collapsed? Isn't this indicative of an explosion occurring in each tower?
6. How could the WTC towers collapse in only 11 seconds (WTC 1) and 9 seconds (WTC 2)speeds that approximate that of a ball dropped from similar height in a vacuum (with no air resistance)?
7a. How could the steel have melted if the fires in the WTC towers werent hot enough to do so? OR 7b. Since the melting point of steel is about 2,700 degrees Fahrenheit, the temperature of jet fuel fires does not exceed 1,800 degrees Fahrenheit and Underwriters Laboratories (UL) certified the steel in the WTC towers to 2,000 degrees Fahrenheit for six hours, how could fires have impacted the steel enough to bring down the WTC towers?
8. We know that the sprinkler systems were activated because survivors reported water in the stairwells. If the sprinklers were working, how could there be a 'raging inferno' in the WTC towers?
9. If thick black smoke is characteristic of an oxygen-starved, lower temperature, less intense fire, why was thick black smoke exiting the WTC towers when the fires inside were supposed to be extremely hot?
10. Why were people seen in the gaps left by the plane impacts if the heat from the fires behind them was so excessive?
11. Why do some photographs show a yellow stream of molten metal pouring down the side of WTC2 that NIST claims was aluminum from the crashed plane although aluminum burns with a white glow?
12. Did the NIST investigation look for evidence of the WTC towers being brought down by controlled demolition? Was the steel tested for explosives or thermite residues? The combination of thermite and sulfur (called thermate) "slices through steel like a hot knife through butter."
13. Why did the NIST investigation not consider reports of molten steel in the wreckage from the WTC towers?
14. Why is the NIST investigation of the collapse of WTC 7 (the 47-story office building that collapsed on Sept. 11, 2001, hours after the towers) taking so long to complete? Is a controlled demolition hypothesis being considered to explain the collapse?
1. If the World Trade Center (WTC) towers were designed to withstand multiple impacts by Boeing 707 aircraft, why did the impact of individual 767s cause so much damage?
All good questions....let's start with the first one, War. What is .gov telling you to say about this one?
World Trade Center Seven collapsed on September 11, 2001, at 5:20 p.m. There were no known casualties due to this collapse. The performance of WTC 7 is of significant interest because it appears the collapse was due primarily to fire, rather than any impact damage from the collapsing towers. [On the contrary, it appears the collapse was due primarily due to a controlled demolition.] Prior to September 11, 2001, there was little, if any, record of fire-induced collapse of large fire-protected steel buildings. [Before September 11, no steel framed skyscraper had ever collapsed due to fire.]
[On September 11, WTC 7 collapsed totally. It is suggested by the official report that this collapse was exclusively due to fire. No significant evidence is offered to back up this suggestion (after all it is only a suggestion). It should be emphasized that WTC 7 was neither hit by an aircraft nor by significant quantities of debris from the collapse of the twin towers. It is also widely claimed that WTC 1 and WTC 2 collapsed mainly due to fire. I emphasize, that before September 11, no steel framed skyscraper had ever collapsed due to fire. However, on September 11, it is claimed that three steel framed skyscrapers collapsed mainly, or totally, due to fire.]
[As you can see from the above animated-gif, the collapse of WTC 7 certainly has the appearance of a controlled demolition. But, judge for yourself, download and watch the following short video clips and a larger version of the animated-gif:
A Video of the collapse of WTC 7.
Another video of the collapse of WTC 7.
And another video of the collapse of WTC 7.
And yet another video of the collapse of WTC 7.
A larger (3.3 MB) version of the above animated-gif. ]
So we have been presented with the following absurd story:
1. Power to the Twin Towers was wired from the substation in WTC 7 through two separate systems. The first provided power throughout each building; the second provided power only to the emergency systems. In the event of fire, power would only be provided to the emergency systems. This was to prevent arcing electric lines igniting new fires and to reduce the risk of firefighters being electrocuted. There were also six 1,200 kW emergency power generators located in the sixth basement (B-6) level of the towers, which provided a backup power supply. These also had normal and emergency subsystems.
2. Previous to the collapse of the South Tower, the power to the towers was switched to the emergency subsystem to provide power for communications equipment, elevators, emergency lighting in corridors and stairwells, and fire pumps and safety for firefighters. At this time power was still provided by the WTC 7 substation.
3. Con Ed reported that "the feeders supplying power to WTC 7 were de-energized at 9:59 a.m.". This was due to the South Tower collapse which occurred at the same time.
4. Unfortunately, even though the main power system for the towers was switched off and WTC 7 had been evacuated, a design flaw allowed generators (designed to supply backup power for the WTC complex) to start up and resume an unnecessary and unwanted power supply.
5. Unfortunately, debris from the collapse of the north tower (the closest tower) fell across the building known as World Trade Center Six, and then across Vesey Street, and then impacted WTC 7 which is (at closest) 355 feet away from the north tower.
6. Unfortunately, some of this debris penetrated the outer wall of WTC 7, smashed half way through the building, demolishing a concrete masonry wall (in the north half of the building) and then breached a fuel oil pipe that ran across the building just to the north of the masonry wall.
7. Unfortunately, though most of the falling debris was cold, it manages to start numerous fires in WTC 7.
8. Unfortunately, even with the outbreak of numerous fires in the building, no decision was made to turn off the generators now supplying electricity to WTC 7. Fortunately, for the firefighters, someone did make the decision not to fight and contain the fires while they were still small, but to wait until the fires were large and out of control. Otherwise, many firefighters may have been electrocuted while fighting the fires.
9. Unfortunately, the safety mechanism that should have shut down the fuel oil pumps (which were powered by electricity) upon the breaching of the fuel line, failed to work and fuel oil (diesel) was pumped from the Salomon Smith Barney tanks on the ground floor onto the 5th floor where it ignited. The pumps eventually emptied the tanks, pumping some 12,000 gallons in all.
10. Unfortunately, the sprinkler system of WTC 7 malfunctioned and did not extinguish the fires.
11. Unfortunately, the burning diesel heated trusses one and two to the point that they lost their structural integrity.
12. Unfortunately, this then (somehow) caused the whole building to collapse, even though before September 11, no steel framed skyscraper had ever collapsed due to fire.
Feel free to wax eloquently about what a moron you are...believe me...it's entertaining...
War, I got to say, you're a fucking asshole.
I did respect your response on various postings, but on this, you're a piece of crap. It's beneath you, but since you've gone apeshit on Obamalamadigdong, I guess I can't expect anything more.
Such a shame.
Oh, hey Rotara, I forgot to include you! Go fuck yourself!
The whole aim of practical politics is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary. - Henry Louis Mencken
1. If the World Trade Center (WTC) towers were designed to withstand multiple impacts by Boeing 707 aircraft, why did the impact of individual 767s cause so much damage?
They didn't cause that much damage. The WTC towers took jet planes hitting it at their highest speed and only swayed about as much as it would on a windy day. The damage caused was mostly to the exterior. The central core columns would have sustained very little to no damage due to the exterior columns absorbing most of the blow and significantly slowing down any remaining debris of the plane.
