The plane that crashed in Pennsylvania was United Airlines Flight 93. It was originally headed from Newark International Airport in New Jersey to San Francisco International Airport in California. The plane was hijacked as part of the September 11, 2001 terrorist attacks, and the hijackers planned to crash it into a federal government building in Washington, D.C. The passengers fought back, preventing the plane from reaching its intended target, and it crashed in a field in Stonycreek Township, Somerset County, Pennsylvania, about 130 miles northwest of Washington, D.C. The intended target of the hijackers is believed to have been the U.S. Capitol Building in Washington, D.C. The crash happened at 10:03 a.m., about 20 minutes flying time from Washington, D.C.
