The symbols on the official New York State September 11 Memorial Flag evoke what was lost on September 11th and what still endures. The 40 yellow stars represent the fatalities upon United Flight 93 that crashed near Shanksville, Pennsylvania. The five-sided figures represent the Pentagon, where 125 people died. At the center of the flag are the Twin Towers, where the greatest loss of life occurred that day. The flag measures 45 inches x 60 inches.
