A gleaming steel and concrete tower complete with wind chimes now commemorates the people who kept hijackers from flying a plane into the U.S. Capitol 17 years ago this week. The 93-foot tall Tower Of Voices, dedicated this week, includes 40 wind chimes, one for each person on United Airlines Flight 93. Passengers and crew members overpowered the hijackers and crashed the jetliner in a field near Shanksville, Pennsylvania, about an hour and a half southeast of Pittsburgh on September 11th, 2001. Yesterday's ceremony dedicated the final piece of the 22-hundred acre Flight 93 National Memorial. President Trump will visit Memorial Plaza on 9/11.
