New York City, N.Y. (Sept. 9, 2004) - As the anniversary of the September 11, 2001 terrorist attack approaches, a test of the Tribute in Light Memorial illuminates a passing cloud above lower Manhattan. The twin towers of light, made-up of 44 searchlights near “Ground Zero,” are meant to represent the fallen twin towers of the World Trade Center. Depending on weather conditions, the columns of light can be seen for at least 20 miles around the trade center complex. U.S. Coast Guard photo by Public Affairs 2nd Class Mike Hvozda
