Here, rescue workers and civilians run from the dust cloud that was created by the collapse of the Twin Towers. The toxic cloud included asbestos, glass fibers, steel and cement. And this poisonous plume even caused a specific ailment, known as the World Trade Center cough, which was prevalent among those who worked at the towers’ location following the collapse.
Looking at this image of the wreckage left after the collapse of the Twin Towers, it’s almost impossible to believe that we’re viewing the remains of what were once two of the world’s most imposing buildings. When the towers opened in 1973, they stood more than 1,300 feet tall; then following 9/11, it took eight months to clear away the remaining debris.
