A third plane, American Airlines Flight 77, hit the western side of the Pentagon, just outside Washington, D.C. The fourth hijacked plane, United Airlines Flight 93, crashed down in a field in rural Pennsylvania, never reaching its intended target because its crew and passengers fought back against the terrorists.
Flight 93 dove into the ground in a near vertical trajectory with such speed (500 mph according to reports) that it created a crater 30 feet deep. Popular Mechanics would have us believe that the 3-ton engine part bounced 300 yards from the crater upon impact. According to the official story Flight 93 crashed after four passengers attacked the hijackers in an attempt to gain control of the airplane. Witnesses describe the plane plunging from the sky at a steep angle. For a plane that flew into the ground, Flight 93 left a rather widespread debris field.
