The footage below was captured by an amateur photographer, Richard A. Siegel, on 9-11-01, starting shortly after the planes hit the towers and captures all three buildings as they collapse. This footage was never aired on television, has no political overtones, just raw footage with audio from, as described in the video details, "a guy standing on a pier surrounded by loved ones of those trapped in the buildings."
The film stops and starts periodically throughout in order to get Mr. Siegal's throughts as to what he was witnessing.
It is heartbreaking to hear the reactions of those watching, a woman crying "I have friends in there!" as witnesses watching in horror, interspersed with auido of news reports as journalists, along with the rest of the word watched the tragic events unfold and tried to make sense of what they were seeing.
