On September 11, 2001, the worst terrorist incident in the history of the United States occurred, two hijacked civil airliners crashed into the ** Center World Trade Tower, and the two skyscrapers collapsed; The Pentagon of the US Department of Defense was also attacked, and part of the structure was damaged and collapsed.
At the moment of the disaster, this ** was accidentally photographed and became the most famous ** in the "911 incident".Who is this man? Why is this ** taboo?
September 11, 2001, will forever be the darkest and most painful page in American historyHijacked two civilian airliners and crashed into the Twin Towers in New York one after another.
As a result, nearly 3,000 people were killed, 6,291 were injured, and the direct economic damage was as high as $200 billion, which is 2% of the GDP of the United States that year, and the damage to the world's economy is as high as about 1 trillion US dollars!
At 8:46, a civil aviation plane crashed into the 94th to 98th floors of the North Tower of the World Trade Center at a speed of 490 miles per hour (about 788 kilometers per hour), killing the crew, passengers, and people in the building in an instantThe floors within the impact radius have also become purgatory.
* The violent seismic wave caused the entire building to shake, and the flames and smoke quickly spread upwardJust 17 minutes later, another airliner crashed into the South Tower of the World Trade CenterThe second impact once again caused a large area of people**, and thick smoke and flames shrouded the entire building in a hellish scene.
People caught in the fire began to desperately cry for help, and some chose to commit suicide by jumping off buildings to escape the painThe scene was shocking, with countless people choked to death by the raging flames and billowing smoke, or crushed to death under the rubble when they collapsed.
In the aftermath of the attack, troops across the United States were put on alertAfter receiving the news, the United States** immediately left the inspected elementary school and entered a secret place to ensure safety.
The conspiracy did not stop thereAt 9:37 a.m., another hijacked airliner crashed into the Pentagon, a building of the US Department of Defense, at a speed of 530 miles per hour (about 853 kilometers per hour), causing a partial collapse of the building and the death of a large number of officers.
It sparked unprecedented anger across the United States, rescuers dug up the rubble to search for survivors, and civilians spontaneously participated in the rescue, but unexpectedly at 9:59 a.m. and 10:29 a.mThe North and South Towers collapsed suddenly, killing many rescue workers.
More than 20 years have passed, and the shadow left by the 911 attacks on the United States has not been completely erasedThousands of firefighters, policemen, and rescuers were involved in the process, and tens of thousands suffered from cancer.
These bloody ** all tell the horrors of the time, and the most famous of them isThis one is called"falling man"Target**.
A landmark of New York, the Twin Towers of the World Trade Center suffered damage during the 911 attacksWhen the plane hit the building, the fire spread rapidly, and countless people trapped on the upper floors were in a desperate situation, some banged on the windows to try to escape, but the smoke and flames blocked all way out.
At the tipping point between life and death, some people make a poignant choiceIt may be more enjoyable to end your life by leaping than to choke to death by fire or smoke.
An AP photographer named Richard Drew was filming at the scene when he looked up with a deafening bang and saw that the World Trade Center was on fire.
Out of professionalism, he quickly adjusted the camera to focus on all this, and at this moment a figure fell straight from the sky, and Drew instinctively pressed the shutter to record this heartbreaking moment.
**The man on the ** is on the dividing line between light and dark, with a slender and straight figure, his robe fluttering, not so much jumping off a building, but throwing himself into the sky in a dashing manner, this ** was published on a full page in the New York Times the next day, causing an uproar.
Some accused the newspaper of violating privacy and being cruel to his family, some people think**There is another attempt, this shocking **, because the public is too empathetic and forced to be dusty for 10 years, until 2011, when everyone came out of the haze, resurfaced.
After a follow-up investigation, the man was Jonathan Brire, a sound engineer working at the World Trade Tower, who wore an orange shirt to work as usual that day, and no one expected such a tragedy to happen.
Soon after the plane struck, Jonathan and the rest of the staff were trapped inside, knowing their lives were on the horizon as the fire grew.
Jonathan Briley is an asthma sufferer, and in the smoke-filled environment, Jonathan feels suffocated, and in despair, he chooses to jump off.
The picture of Jonathan's fall was taken 12 times in a row by Drew, which made the witnesses worry, and many people chose to take the initiative to end their lives and jump off with their relatives and friendsWhen the Petronas Twin Towers collapsed, it was left in shambles, with countless lives buried beneath the rubble.
This one"The Man Who Fell"Seeing the choice of human nature in the most extreme environment is both poignant and admirableFor Jonathan and the other tragic victims, it is a great misfortune to have to die in this way, but the courage and dignity with which they died is equally respectable.
The two skyscrapers that once stood in New York were the landmarks of New York at that timeFrom afar, the two glittering 110-storey metal facades soar into the sky, as if they will always stand.
The twin towers are not only the pride of New York, but also the whole of America, but the terrorist attack turned it to ashes, and many people are curiousWhy did the plane crash into a high-rise position, causing the whole to collapse?
The main reason is that the aircraft carries a large amount of jet fuel, which ignites quickly after the impact, forming a fire that is difficult to extinguishTemperatures can reach 800 to 1200 degrees.
Although the twin towers themselves were constructed of reinforced concrete and were designed to be virtually impregnable, catastrophic impacts and monstrous fires exposed their fatal weaknesses.
Although the exterior steel columns and fire-resistant coating of the twin towers are thicker, with high fire resistance and load-bearing capacity, the design of the internal support columns has serious problems.
These support columns are steel structures that are prone to bending or breaking when subjected to high pressures, and these support columns are not connected to the beams by appropriate reinforcement measuresUnder the action of high temperature, this material is very easy to soften and deform, and loses its original bearing capacity.
When the fire hit the twin towers, the steel structure quickly collapsed, exacerbating the collapse of the entire buildingThe steel structure itself will lose its bearing capacity at a high temperature of 450 to 650 degrees, and its strength is close to 0.
Under the action of fuel, the whole building heats up to thousands of degrees in a few seconds, the whole body begins to deform and settle in the high temperature, the frame structure begins to loosen, the key nodes lose their force, and the impact surface collapsesThen the flames continued to burn, and finally they could not bear the bearing of the upper part, and the floors collapsed one after another like dominoes.
More than 20 years later, the 911 terrorist attacks are still an indelible shadowThis ** is a scene of fire and smoke billowing after the building was hit.
Panicked crowds
Hard-working rescuers
Smoke billowed from the air
Purgatory on Earth
In the face of such a catastrophe, human beings seem so insignificant, and it is this helplessness and fragility that makes us more deeply aware of the preciousness and difficulty of the era of peaceEvery time the scars of history are healed, it is at the cost of countless lives and courage.
The design team for the new World Trade Center learned the hard lessons of 911 and made safety a top design considerationAdvanced structural engineering principles are used to enhance the impact resistance of the building and maintain the stability of the overall structure even in extreme situations.
A multi-layered security system has been installed inside the buildingIt includes emergency evacuation routes, fire isolation areas, and comprehensive monitoring and alarm equipment.
The rebuilt World Trade Center is not just a physical revival, it also carries respect for the memory of the past and hope for the futureTowering into the sky, this skyscraper is not only a tribute to the lives lost, but also a declaration to the world that it will never bow down to terrorism!
