United Airlines Flight 93 was en route from Newark International Airport to San Francisco when it was hijacked by four al-Qaeda terrorists, as part of the September 11 attacks. The hijackers stormed the aircraft's cockpit 46 minutes after takeoff and diverted it back toward the east coast, in the direction of Washington, D.C., the U.S. capital. Several passengers and flight attendants learned from phone calls of the other 9/11 suicide attacks, and many passengers attempted to retake the plane from the hijackers. During the struggle, the hijackers deliberately crashed the plane into a field near a reclaimed strip mine in Stonycreek Township, Pennsylvania; all 44 people on board (including the four hijackers) were killed. A temporary memorial was built near the crash site soon after the attacks, and the permanent Flight 93 National Memorial was dedicated on September 10, 2011, with a concrete and glass visitor center situated on a hill overlooking the site.
