At Shanksville, Pennsylvania, in Somerset County, United Airlines Flight 93 crashed during the September 11, 2001 attacks after passengers and crew, having learned of the other hijackings by phone, fought to retake the plane. It was the only one of the four hijacked aircraft that did not reach its intended target, believed to have been the U.S. Capitol or the White House, and all 40 passengers and crew members died. A temporary memorial soon drew large crowds, and federal legislation in 2002 authorized a permanent national memorial. Completed in phases beginning in 2011, it preserves the crash site and honors collective resistance through features aligned with the flight path.
