Engineers had to consider every peril they could imagine when they designed the World Trade Center three decades ago because, at the time, the twin towers were of unprecedented size for structures made of steel and glass. "We looked at every possible thing we could think of that could happen to the buildings, even to the extent of an airplane hitting the side," said John Skilling, head structural engineer. "However, back in those days people didn't think about terrorists very much." Skilling, based in Seattle, is among the world's top structural engineers. He is responsible for much of Seattle's downtown skyline and for several of the world's tallest structures, including the Trade Center. Concerned because of a case where an airplane hit the Empire State Building, Skilling's people did an analysis that showed the towers would withstand the impact of a Boeing 707. "Our analysis indicated the biggest problem would be the fact that all the fuel (from the airplane) would dump into the building. There would be a horrendous fire. A lot of people would be killed," he said. "The building structure would still be there." Skilling - a recognized expert in tall buildings - doesn't think a single 200-pound car bomb would topple or do major structural damage to a Trade Center tower. The supporting columns are closely spaced and even if several were disabled, the others would carry the load. "However," he added, "I'm not saying that properly applied explosives - shaped explosives - of that magnitude could not do a tremendous amount of damage." He took note of the fact that smoke and fire spread throughout the building yesterday. He said that is possibly because the pressurizing system that stops the spread of smoke didn't work when the electric power went off. Skilling, 72, was not involved in the design of the building mechanics. Although Skilling is not an explosives expert, he says there are people who do know enough about building demolition to bring a structure like the Trade Center down. "I would imagine that if you took the top expert in that type of work and gave him the assignment of bringing these buildings down with explosives, I would bet that he could do it." https://www.reddit.com/r/conspiracy/comments/3yb6iz/the_twin_towers_were_designed_to_survive_jet/ They should of wrapped the structural columns in paper passports since you know... they are apparently jet fuel fire resistant. NYC WTC 'designed to withstand multiple airliner impacts' Frank De Martini construction boss Nov 22, 2008 Frank De Martini WTC architect explains it would resist jetliner impacts At the time the Twin Towers were built, the design approach of moving the support columns to the perimeter and the core, thereby creating large expanses of unobstructed floor space, was relatively new, and unique for a skyscraper. However, that approach is commonplace in contemporary skyscrapers. Frank Demartini's Statement Frank A. Demartini, on-site construction manager for the World Trade Center, spoke of the resilience of the towers in an interview recorded on January 25, 2001. The building was designed to have a fully loaded 707 crash into it. That was the largest plane at the time. I believe that the building probably could sustain multiple impacts of jetliners because this structure is like the mosquito netting on your screen door -- this intense grid -- and the jet plane is just a pencil puncturing that screen netting. It really does nothing to the screen netting. Demartini, who had an office on the 88th floor of the North Tower, has been missing since the 9/11/01 attack, having remained in the North Tower to assist in the evacuation. 6 Demartini had first worked at World Trade Center when Leslie E. Robertson Associates hired him to assess damage from the truck bombing in 1993. LINK Like All Skyscrapers, the Twin Towers Were Over-Engineered One aspect of engineering that is not widely understood is that structures are over-engineered as a matter of standard practice. 7 Steel structures like bridges and buildings are typically designed to withstand five times anticipated static loads and 3 times anticipated dynamic loads. The anticipated loads are the largest ones expected during the life of the structure, like the worst hurricane or earthquake occurring while the floors are packed with standing-room-only crowds. Given that September 11th was not a windy day, and that there were not throngs of people in the upper floors, the critical load ratio was probably well over 10, meaning that more than nine-tenths of the columns at the same level would have to fail before the weight of the top could have overcome the support capacity of the remaining columns. There is evidence that the Twin Towers were designed with an even greater measure of reserve strength than typical large buildings. According to the 1964 white paper cited above, a Tower would still be able to withstand a 100-mile-per-hour wind after all the perimeter columns on one face and some of the columns on each adjacent face had been cut. 8 Also, John Skilling is cited by the Engineering News Record for the claim that "live loads on these [perimeter] columns can be increased more than 2000% before failure occurs."

There was a report that came out the because people were afraid of this fact the test done to prove the Twin Towers were airplane proof was rigged to create the result needed for the publicity. Sort of how VW cheated on their diesel miles test.
Bringing down buildings the size of the WTC would take months of preparation, and an enormous amount of explosives. Please read the following article by PROTEC at http://www.implosionworld.com/Article-WTC%20STUDY%208- 06%20w%20clarif%20as%20of%209-8-06%20.pdf.
"A silly idea is current that good people do not know what temptation means. This is an obvious lie. Only those who try to resist temptation know how strong it is... A man who gives in to temptation after five minutes simply does not know what it would have been like an hour later. That is why bad people, in one sense, know very little about badness. They have lived a sheltered life by always giving in.” ― C.S. Lewis, Mere Christianity
Apparently the Seattle Times was wrong.
From the Implosionworld.com site. "Although every speaker captivated the standing-room only crowd with various stories, it was Dannenfelser who provided some of the most compelling observations. Having spent months coordinating retrieval efforts at the Fresh Kills Landfill in Staten Island, he spoke of working closely with the FBI and other agencies in developing various types of debris filtering machines, including one that could recognize small amounts of "human material" for DNA identification. He also spoke of retrieving, "about 10,000 pieces of the airplanes, which I kept in a pile by my truck for safekeeping." "A silly idea is current that good people do not know what temptation means. This is an obvious lie. Only those who try to resist temptation know how strong it is...

Missing? He died in the collapse he said could not happen. ------------------ ---------------------- The towers were designed to survive the accidental impact of a 707, lost in the fog, trying to land, and low on fuel -- similar to the circumstances of the B-25 Mitchell bomber that struck the Empire State Building in 1945. The speed used was landing speed -- 180 mph. This study was done by Leslie Robertson, lead structural engineer of the WTC. The Port Authority claims the study was based on 600 mph. We'll never know -- Robertson says the study (and all his calculations) have been lost. BUT, the important fact is that the towers DID survive the impact. Thousands of people escaped. The fire brought them down -- the effects of which were NEVER factored into the calculations. Robertson himself stated: "To the best of our knowledge, little was known about the effects of a fire from such an aircraft, and no designs were prepared for that circumstance. Indeed, at that time, no fireproofing systems were available to control the effects of such fires."
They were correct. The towers survived the collision. Because they survived, 15,000 people successfully evacuated the two towers.
Apparently the Seattle Times was wrong. That is understating it. They was wrong twice. 707.200 is not a 767.200 and you can fudge the numbers to make them close but they were not. I truly am sick of the the 911 truthers. Nothing has panned out and all they do is hurt those that died that day because of terrorist attacks. 911 Truthers are just like Man Global warmest. They just keep making shit up to fit their desires. After awhile you would think that everything they slung up at the wall did stick and they would go away in time. But no they just are mentally disturbed.
They were correct. The towers survived the collision. The towers survived the collision. Not for a long time. would you have preferred the people stayed in the building and confidently sent out for pizza to prove your stupid point instead of scurrying out of the building? You're nuts.
Correct. They survived the collision but not the fire. The calculations were based on a collision-only. They never took into account the effects of an extended 1800 degree jet fuel fire.
They made an effort to deny the legitimate consequeses of anything that would forseeably happen as a predictable result of that collision. Why?
It's simple derangement. They need this to justify their hate/anger towards... I don't know. But. They truly are detached from reality.

It really does nothing to the screen netting. Facts are anathema to the Official Government Fairy Tale cultists who infest this site. In a Cop Culture, the Bill of Rights Doesn’t Amount to Much Unfortunately, the opinion of an insurance agent doesn't mean a heck of a lot. In a Cop Culture, the Bill of Rights Doesn’t Amount to Much The Beijing Mandarin Oriental Hotel Fire The most recent example of a spectacular skyscraper fire was the burning of the Hotel Mandarin Oriental starting on February 9, 2009. The nearly completed 520-foot-tall skyscraper in Beijing caught fire around 8:00 pm, was engulfed within 20 minutes, and burned for at least 3 hours until midnight. Despite the fact that the fire extended across all of the floors for a period of time and burned out of control for hours, no large portion of the structure collapsed. It is tempting to draw parallels between this spectacle and the destruction of WTC 1, 2, and 7 because of the stark opposites: on 9/11/01, three skyscrapers were transformed into piles of rubble primarily as a consequence, supposedly, of fires -- fires spanning small fractions of each building; and on 2/09/09, a skyscraper remained intact after burning like a torch for hours. However such parallels may be limited by major structural differences between the buildings in the two cases -- one being that the Hotel Mandarin Oriental, designed by the famous Dutch architect Rem Koolhaas, had a full-height interior atrium, and thus had the hollowness that the 9-11 Commission deceptively attempted to attribute to the Twin Towers. 10 Perhaps the relevance of the Mandarin fire to the events of 9/11/2001 is more symbolic than forensic. The Mandarin fire is examined more fully here. On February 9, 2009, in the middle of the Lunar New Year, the distinctive 40-story Mandarin Oriental hotel in Beijing's Television Cultural Centre (TVCC) erupted in sparks and flames that consumed the building from top to bottom in an intense fire lasing for several hours. Blamed on a ground-based fireworks display gone afoul or illegal fireworks operations inside of the building, the fire started around the tower's top and proceded downward around the tower's sides while fireworks continued to burst dramatically above the blaze. 1 The spectacular torching of the Mandarin tower further underscores the anomalous nature of the official explanation of the total collapse of the Twin Towers and WTC 7 -- an explanation that primarily blames fires for causing the "global collapse" of those structures. It is yet another example of a severe fire that failed to induce even the partial collapse of a skyscraper. Although less similar to the WTC towers than other skyscrapers ravaged by fires, the Mandarin tower is notable for the magnitude of the fire it withstood -- a fire that dwarfed the fires that preceded the "collapses" of each of the the WTC skyscrapers. Coming exactly 2711 days after 9/11/2001, the burning of the Hotel Mandarin Oriental, which was unoccupied pending its completion, killed one firefighter. In a Cop Culture, the Bill of Rights Doesn’t Amount to Much Many Americans have been fed so many lies over so many years they seem unable to reason at all anymore. Quite sad, really. Some here no doubt would love to make thinking outside the box illegal. A bankrupt nation full of bankrupt serfs. They never thought the CIA and their deeds would come back around and can't see it when it's in front of their faces Happy New Year fellow truth seeker, 2016 just might be a wild year.
My, how harsh. I'm kind of sick of people that don't give a damn that their country has been looted and their liberties stolen by a bunch of lying scumbags. So there. How did you feel about Galileo, BTW? Bet ya would have flogged him like the sycophant you are. Here's a challenge, sport- watch this little video about 4 wives of 911 victims. You can hear what they think straight from their mouths. I DARE YOU Then stop spreading dirty ignorant lies. OK? DOES THAT MAKE IT CLEAR TO YOU THAT YOU HAVE NO IDEA WHAT YOU'RE TALKING ABOUT?
In any hypothetical, you must define the parameters. The engineers were asked to predict the survivability of the WTC if hit by: a) a 707 They were NOT asked about a 767, fully fueled, and flying at 600 mph. Nor did they have the capability to predict the effects of a jet fuel fire. And even if they did, no fireproofing systems were available at the time to control the effects of such fires.
Meaning there was nothing in the building -- no furniture, drapes, carpet, papers, etc. And no structural damage before the fire. And no jet fuel. Other than that, this is a perfect match.
Yes it truly is sad. I will never forget hearing C. Rice on national TV say that " no one could imagine terrorists crashing hijacked planes into buildings." And knowing she was lying through her teeth!! I do not know what happened, by who, or why. But I am convinced that the entire official story about 9-11 is a huge pile of bull shit! Si vis pacem, para bellum Those who beat their swords into plowshares will plow for those who don't Rebellion to tyrants is obedience to God. There are no Carthaginian terrorists. “The object of war is not to die for your country but to make the other bastard die for his.” - George S. Patton
