The Flight 93 National Memorial is located in Somerset County, Pennsylvania, approximately 78 miles (126 km) southeast of downtown Pittsburgh. Under normal traffic conditions, the drive takes about 1 hour and 30 minutes via the Pennsylvania Turnpike (I-76). The memorial is situated near the town of Shanksville and covers over 2,200 acres of what was formerly a reclaimed strip mine. It serves as a somber tribute to the 40 passengers and crew members who thwarted a terrorist attack on September 11, 2001. The site features a Visitor Center with a panoramic view of the crash site, the "Wall of Names" made of white Italian marble, and the 93-foot-tall "Tower of Voices," which contains 40 wind chimes. Because the site is located in a rural mountain area, cell service can be spotty, and visitors are encouraged to check the weather beforehand, as the high-altitude plateau can be significantly colder and windier than the city of Pittsburgh.
