where was the fourth plane headed on 9/11

The fourth plane on 9/11, United Airlines Flight 93, was headed for Washington, D.C., with the most likely target being the United States Capitol. Some reports also mention that the White House was a potential target. However, due to the passengers' revolt to regain control of the plane, it crashed in a field in Somerset County, Pennsylvania, before reaching its intended target. The plane was hijacked approximately 46 minutes into the flight and was turned southeast towards Washington, D.C. by the terrorists. The passengers' intervention prevented the plane from hitting its target, resulting in the crash at about 10:03 a.m. in rural Pennsylvania.
