National Institute of Standards and Technology. p.17 . Retrieved January 2, 2023. The destruction of the Twin Towers has been called "the most infamous paradigm" of progressive collapse. [24] Each collapse began with the local failure of the vertical load-bearing components of the floors that were hit by the planes and progressed to encompass the whole of the structure. [59] Structural components were severed, releasing gravitational energy that transferred loads downwards by way of serially propagating impact forces. [60] Excepting the top floors of the building, which would not have released sufficient gravitational energy to bring about a total collapse, the collapses could have begun with the failure of any story.

But some of the same impressive architectural elements may have also helped worsen the tragedy on the fateful morning of September 11, 2001. Calling the project “the architecture of power,” Ada Louise Huxtable, an architecture critic for The New York Times offered a prescient warning when the towers were going up in 1966: “The trade-center towers could be the start of a new skyscraper age or the biggest tombstones in the world,” she wrote.

As part of its research into where the fire was at its most intense, NIST analysed camera footage and still photographs, and counted 104 jumpers, often recording the floor and exact window from which they left.

The structural engineers working on the World Trade Center considered the possibility that aircraft could crash into the building. In July 1945, a B-25 bomber that was lost in fog had crashed into the 79th floor of the Empire State Building. [25] A year later, a C-45F Expeditor crashed into the 40 Wall Street building. Once again, fog was believed to have been the contributing factor in the collision. [26] Leslie Robertson, one of the chief engineers working on the design of the World Trade Center, said that he considered the scenario of the impact of a Boeing 707, which might be lost in the fog and flying at relatively low speeds while seeking to land at either JFK or Newark Airports. [27] In an interview with the BBC two months after the towers collapsed, Robertson said: "with the 707, the fuel load was not considered in the design. I don't know how it could have been considered." He also said that the main difference between the design studies and the event that caused the towers to collapse was the velocity of the impact, which greatly increased the absorbed energy, and was never considered during the construction process.

He even walks her to school one day with the intent of transferring her to another school. When he talks with her teachers and principal, however, he decides against it; but he still will not talk with Deja about why the Towers upset him so much. She eventually finds a name tag in his suitcase that shows he was employed at the Towers, but she dare not bring it up to him for fear of upsetting him more.

All told, emergency personnel killed as a result of the collapse included 342 [l] members of the New York City Fire Department (FDNY), 71 law enforcement officers including 23 members of the New York City Police Department (NYPD), 37 members of the Port Authority Police Department (PAPD), five members of the New York State Office of Tax Enforcement (OTE), three officers of the New York State Office of Court Administration (OCA), one fire marshal of the New York City Fire Department (FDNY) who had sworn law enforcement powers (and was also among the 343 FDNY members killed), one member of the Federal Bureau of Investigation (FBI), and one member of the United States Secret Service (USSS). The total death toll for civilian and non-civilians is estimated to be 2,606 persons.
