Friday marks 14 years since Sept. 11, 2001, and to commemorate those who died on United Flight 93, which crashed in a field in Shanksville, Pa. when its passengers prevented hijackers from reaching its intended destination (likely the U.S. Capitol), the National Parks Service dedicated a memorial to the flight on Sept. 10.
The Flight 93 National Memorial includes a museum and an outdoor walkway that follows United 93’s flight path to an overlook of the impact site (pictured above). Click through to the memorial’s official Facebook page to see more photos.
