Flight 93 memorial tower set to open on 17th anniversary of 9/11

The final phase of the Flight 93 National Memorial is underway and on track to open on the 17th anniversary of plane’s crash into a Pennsylvania field during 9/11.

United Airlines Flight 93 was en route from Newark, N.J., to San Francisco on Sept. 11, 2001, when hijackers seized control and redirected the plane toward Washington, D.C. But 40 passengers and crew members fought back, and the hijackers responded by crashing the plane into the field near Shanksville, about 60 miles southwest of Pittsburgh.

Amid the remote, rolling hills, a national park has taken shape to honor the victims.

The final phase of the memorial will include a 93-foot tower at the entrance with wind chimes for each of the victims and a grove of trees, called the Tower of Voices.

The 93-foot-tall tower will feature 40 tubular metal wind chimes, one each for the 33 passengers and seven crew members who died. It’s designed to serve as a visual and audible reminder of the heroism of those on board. Each chime will have a different tone, or voice.

A memorial plaza was completed in time for the 10th anniversary of the attacks in 2011. It features a white stone wall, which traces the path of the doomed flight, with separate panels for each victim’s name.

An immersive visitor center, completed in 2015, sits on a hill overlooking the crash site. It uses photos, video, artifacts and interactive displays to tell the story of Flight 93, the only jetliner among the four commandeered by terrorists that failed to reach its intended target.
