Flight 93 National Memorial

The Flight 93 National Memorial, near Shanksville, PA, is a new 2,200-acre national park where, on September 11, 2001, United Airlines Flight 93 came to earth in an open field after a heroic effort by passengers and crew prevented the hijacked plane from crashing into its intended target, the United States Capitol in Washington, DC. LEED-NC Gold.

  • The site, a reclaimed coal strip mine, serves as the foundation for the sustainability strategy.
  • The Memorial is as an integrated landscape and sequence of natural features,
  • Visitors enter the Memorial through a tower of voices near the park entrance, tour a memorial and visitors' center overlooking the crash site, and ultimately walk along the crash site’s edge.
  • The LEED strategy was designed to reinforce the Flight 93 story.
