Stonycreek Township, Somerset County, Pennsylvania in the context of "San Francisco International Airport"

The Flight 93 National Memorial is a memorial built to commemorate the crash of United Airlines Flight 93, which was one of four aircraft hijacked during the September 11 attacks in 2001. The memorial is located in Somerset County, Pennsylvania, with the vast majority in Stonycreek Township, and with a small portion in Shade Township. It is 78 miles (126 km) southeast of Pittsburgh, 122 miles (196 km) west of Harrisburg (the state capital), and 226 miles (364 km) west of Philadelphia.

A national memorial was created to honor the passengers and crew of Flight 93, who stopped the terrorists from reaching their target by fighting the hijackers. A temporary memorial to the 40 victims was established soon after the crash. The first phase of the permanent memorial was completed, opened, and dedicated on September 10, 2011. The design for the memorial is a modified version of the entry Crescent of Embrace by Paul and Milena Murdoch.

Shanksville garnered global attention during the September 11 attacks when United Airlines Flight 93, bound from Newark, New Jersey, for San Francisco, crashed in adjacent Stonycreek Township after its passengers rebelled against the flight's al-Qaeda terrorist hijackers. It was the only one of the four hijacked planes that failed to reach the terrorists' intended target.
