A memorial to those who lost their lives September 11, 2001 on Flight 93 has opened, 14 years after the terrorist attacks that led to their demise.

The  Flight 93 National Memorial and visitor center complex, operated by the National Park Service, includes a permanent exhibit on the flight, a multi-use meeting space, walking paths, a flight-plan walkway and an area that allows visitors to view the flight's crash site from a distance.

It was the passengers of Flight 93 who famously rebelled against hijackers, and in doing so, prevented the plan from crashing into the United States Capitol. All 33 passengers and seven crew members were killed.

Officials believe that the memorial, which cost $26 million dollars to build will draw between 300,000 to 500,000 visitors each year.
