So when and how did the Towers fall and what does the World Trade Center look like now in the wake of the catastrophic attacks? On the morning of Tuesday, September 11, , nineteen Islamic terrorists hijacked four planes in a coordinated attack on US soil. Two of the planes were flown into the Twin Towers of the World Trade Center in New York City.

The first American Airlines Boeing Flight 11 crashed into the north tower of the World Trade Center at 8. The crash left a burning hole near the 80th floor of the storey skyscraper, instantly killing hundreds of people and trapping many more in higher floors. Taking less than an hour to burn, the south tower collapsed in a massive cloud of dust and smoke.

They were part of a complex of seven buildings, located in the Financial District of Lower Manhattan, New York City. The towers could accomodate 50, workers and , daily visitors in 10 million square feet of space. They were the hub of the bustling Financial District, a top tourist attraction and a symbol of America. The strike was the most devastating terror attack on US soil and would change the course of world events forever.

In the immediate aftermath of the destruction, the site changed its name to Ground Zero to commemorate where the World Trade Center once stood. The term is used to describe the site of a nuclear explosion and later was used to refer to the point of any dramatic or violent event. The

By: Clint Pumphrey. Ask any American and they’ll tell you where they were when al-Qaeda terrorists attacked New York City’s World Trade Center towers on Sept. Millions of people across the nation stood slack-jawed in front of televisions as they watched airplanes slam into lower Manhattan’s two tallest skyscrapers with fiery force. When it seemed that the country’s worst fears had already been realized, the story buildings collapsed, engulfing those fleeing the scene in a dusty cloud of debris.

As people struggled to come to terms with the horrific events of that day, they wondered, how could such massive structures be reduced to a pile of rubble? This wasn’t the first time the World Trade Center had been targeted by Islamic extremists. On Feb. While this earlier attack blew a crater feet To many Americans, the towering skyscrapers seemed indestructible. Less than a decade later, this perception would be contradicted in dramatic fashion.

Skies were clear as residents flooded the city’s streets and subways to make their morning commute. Then, at a. Startled New Yorkers turned their eyes to the top of the city’s skyline and wondered whether this was an accident, or perhaps something more sinister. Such questions were laid to rest at a.

In the years since the terrorist attacks in New York City, individual engineers and committees of experts have studied the crumpling of the World Trade Center twin towers. By examining the building’s destruction step-by-step, experts are learning how buildings fail and discovering ways to build stronger structures by answering the question: What caused the twin towers to fall? When hijacked commercial jets piloted by terrorists struck the twin towers, some 10, gallons 38 kiloliters of jet fuel-fed an enormous fireball.

Like most buildings, the twin towers had a redundant design, which means that when one system fails, another carries the load. Each of the twin towers had columns around a central core that housed the elevators, stairwells, mechanical systems, and utilities. In this tubular design system, when some columns became damaged, others could still support the building.

Belgian civil engineer Arthur Vierendeel is known for inventing a vertical rectangular metal framework that shifts shear differently than diagonal triangular methods. The impact of the aircraft and other flying objects:. The shift put some of the columns under „elevated states of stress. Even if the sprinklers had been working, they could not have maintained enough pressure to stop the fire.

Template:Pp-move-vandalism Template:Coord. The collapse of 2 World Trade Center seen from Williamsburg, Brooklyn. The twin towers of the World Trade Center collapsed on September 11, , as a result of the September 11 attacks , [1] in which terrorists affiliated with al-Qaeda hijacked four commercial passenger jet airliners , flying one into the North Tower 1 World Trade Center and another into the South Tower 2 World Trade Center.

Later that day, 7 World Trade Center collapsed at p. Debris from the collapsing towers severely damaged or destroyed more than a dozen other adjacent and nearby structures. The Federal Emergency Management Agency FEMA completed its performance study of the buildings in May It declared that the WTC design had been sound, and attributed the collapses wholly to extraordinary factors beyond the control of the builders.

While calling for further study, FEMA suggested that the collapses were probably initiated by weakening of the floor joists by the fires that resulted from the aircraft impacts. According to FEMA’s report, the floors detached from the main structure of the building and fell onto each other, initiating a progressive „pancake“ collapse.

FEMA’s early investigation was revised by a later, more detailed investigation conducted by the National Institute of Standards and Technology NIST , which also consulted outside engineering entities. This investigation was completed in September

By: Tom Harris. When we look back on September 11, , we think mainly of people. We mourn for the victims of the attacks, we empathize with their families, we honor the rescue workers, and we reflect on our own experience. At the same time, we remember all of the technology of that day — the airplanes that the hijackers used as flying bombs, the buildings they damaged and destroyed, and the heavy equipment used in the massive rescue and then clean-up effort.

Like countless events throughout history, the attacks of September 11 were a crushing mesh of man and machine. The most prominent technology on that day, of course, was the World Trade Center complex. After the attack, the WTC’s Twin Towers came to symbolize not only the day itself, but also a collective emotion of people all over the world. In this article, we remember the Twin Towers for everything they were: a remarkable technological achievement, a representation of an ideal, and, ultimately, a staggering reminder of our own vulnerability.

Rockefeller’s many grandsons. In fact, the idea was proposed soon after World War II, a decade before Rockefeller ever got involved, but he was the one who actually got the ball rolling. He hoped to energize the area with new construction, in much the same way his father revitalized midtown Manhattan in the s with Rockefeller Center.

The NIST claimed that embers ignited a fire which then caused the storey building to collapse on itself at p. For expediency and because it was not hit by a plane, the study looked only at WTC 7 not the other two but AET has long claimed all three were subject to something beyond heat induced failure. Further, he says, the debris from WTC 1 which fell feet to WTC 7 did not attain sufficient mass to cause structural damage to the steel in that building.

The bottom line, he says, is that the NIST report is flawed and of no value to future engineering or architectural learning. The Alaska report adds new momentum to long standing claims by the AET that all three of the buildings should not have collapsed in the spectacular and deadly manner they did. Further, and Korol underlines this, there was nothing in the offices beyond basic desks, chairs, computers and paper that would be of such a combustible nature so as to feed a fire and raise the temperature to above 1, degrees Celsius and melt the steel structure.

UAF civil engineering professor Leroy Hulsey, principal investigator, his research assistants, Feng Xiao, now an associate professor at Nanjing University of Science and Technology and Zhili Quan, now a bridge engineer for the South Carolina Department of Transportation, found that the design standard of the building was not exceeded by the fire and that simultaneous and controlled demolition caused the structural steel to fail.

It was also the first NIST finding of a highrise collapse from thermal deformation caused by fire which the page Alaska report disputes. It presents arguments showing it was a simultaneous global failure not a localized failure causing a domino effect. Hulsey et al argue that the collapse was straight down in a pancake fashion with about 2. The study team undertook extensive computer and physical modelling, paying particular attention to the area around Column 79 which had been identified as the critical juncture of failure.

Their conclusion is that Columns 79, 80, and 81 did not fail at the lower floors of the building and were not subjected to heat above floor 30 because there were no fires there.

I arrived for work that morning on the 77th floor of World Trade Center tower 2 WTC2 around a. It was a bright, beautiful morning, and you could see seemingly forever out the floor to ceiling windows of the building. My company had offices on the 77th and 78th floors. My office was on 77 facing WTC1 the north tower. I was standing in the hallway outside my office talking to a co-worker, when I heard a tremendous explosion at a.

I looked into my office office wall was floor-to-ceiling glass and saw a gaping hole in the south side of WTC1. We had no idea what had happened. No part of the plane was visible it had hit WTC1 from the North—the opposite side from where my office faced. Eventually word filtered in from somewhere that it was a plane that hit the building. I just assumed it was a terrible accident. At some point I saw people appear at the edge of the gaping hole.

Your mind cannot really comprehend what is happening—almost an overload state. You see it with your eyes, but you are somehow mentally detached from it at the same time. I called my wife to let her know what was happening.
