The events of September 11, 2001, left an indelible mark on the country, and indeed the world. Today, New York will commemorate the 11th anniversary of 9/11 with a series of ceremonies and memorial services. It will also celebrate the progress underway on the new World Trade Center towers, which serve as a reminder of America’s ability to overcome adversity. The most prominent tower, called WTC1, was photographed yesterday in all of its red-white-and-blue glory by Flickr user Gus NYC. When completed, WTC1 will be the tallest building in the Western Hemisphere.
