The Flight 93 National Memorial protects the site of the crash of United Airlines Flight 93, which was hijacked as part of the terrorist attacks of September 11, 2001.
Often shortened to "9/11", this was the worst terrorist attack in American history. One of four stolen planes that day, United 93 was crashed by some of the passengers as they tried to regain control after learning of the other planes. Two had already been crashed into New York City's World Trade Center and a third into the Pentagon in Washington, DC. It is presumed that the hijacker's target for Flight 93 was the White House with the goal of killing President George W. Bush.
The memorial has the plain shape of a circle bisected by the flight's trajectory. A circular path lines with red maple trees that follows the natural bowl shape of the land. The walkway eventually widens in from a ceremonial gate, shown in bronze and the wall of names, composed of 40 panels of 3-inch-thick slabs of polished white granite, 8 feet tall, each inscribed with a name of the 40 heroes. Two walls flanking the gate are clad in polished white granite and the flight path is paved with black granite. Beyond the gate is the impact site, shown planted with wildflowers, and the hemlock grove beyond.
Although often called Shanksville, the site is actually located in Stoneycreek, a town near Shanksville. The memorial is managed by the National Parks Service.
The memorial's operating hours depend on the season.
From April through September, the memorial is open daily 9:00 a.m.; to 7:00 p.m. From October through March, it is open 9:00 a.m. to 5:00 p.m.
