Visitor center honors Flight 93

A new visitor center has been dedicated on a Pennsylvania hill overlooking the site where United Airlines Flight 93 came down during the Sept. 11 attacks.

The visitor center is at the Flight 93 National Memorial near Shanksville. It uses photos, video, artifacts and interactive displays to tell the story of how passengers and crew members tried to regain control of the plane.

The hijackers are believed to have wanted to crash it into the U.S. Capitol.

Friday is the 14th anniversary of the attacks.
