Time magazine asked photo editors to pick the images that moved them as they selected images to capture the horror of 9/11. Olivier Picard, former director of photography for U.S. News & World Report, chose this image by Patrick Witty (now international picture editor for Time). Picard says the image “best evokes that tumultuous morning. It is 9:59 a.m. and New Yorkers witness the collapse of the South Tower. Their reaction was mine. Immediate. Disbelief. Raw. Violent.”
