The survival of several video recordings of Building 7's collapse, though of low resolution, allow study of the building's motion and the time of collapse.
Each of the following videos shows the entire visible portion of the building falling with a vertical precision otherwise seen only in controlled demolition. Moreover, they show that the collapse took only about 6.5 seconds from start to finish. That rate of fall is within a second of the time it would take an object to fall from the building's roof with no air resistance.
