On September 11, 2001, my wife and I were living in the Williamsburg neighborhood of Brooklyn, NY.  From our  balcony, we had a partial view of the World Trade Towers.  I took video footage of the towers before their catastrophic collapse as well as footage of the seemingly normal activity on the streets below in the aftermath.  In the days following 9/11, we went into Manhattan, where I filmed the spontaneous gatherings at Union Square as well as various other scenes that caught my attention.
