How did he know DC was the target?
http://www.thepittsburghchannel.com/news/957912/detail.html"It sure wasn't going to go down in rural Pennsylvania," U.S. Rep. John Murtha, D-Pa., said Wednesday. "The target was Washington, D.C. Somebody made a heroic effort to keep the plane from hitting a populated area.
"I would conclude there was a struggle and a heroic individual decided 'I'm going to die anyway. I might as well bring the plane down here.'"

Witnesses reported seeing military aircraft in the air just after the crash, and there were rumors that Flight 93 was shot down. Secretary of State Donald Rumsfeld said that was not the case, according to Murtha.
And on 9/13:

John Murtha, the ranking Democrat on the House Appropriations defense subcommittee, said Wednesday at the crash site near Shanksville, Pa., he believes a struggle took place in the cockpit and the plane was headed for a significant target in Washington. "There had to have been a struggle, and someone heroically kept the plane from heading to Washington," Murtha said.
Whoever was ultimately in control of the plane, Flight 93 made a number of odd maneuvers in midair before it finally plunged to Earth. "Halfway through its trip, around Weston, W.Va., it took some sharp turns, all within about two or three minutes," said Jeff Krawczyk, chief executive of Flight Explorer, a software firm that uses Federal Aviation Administration data to track flights.
"It was going west, then took a turn to the north, and then went west again," Krawczyk said. Then the plane headed toward Kentucky and took a sharp turn south toward Washington, and around that time the FAA center in Cleveland lost contact with the flight, apparently because someone aboard had turned off its transponder, he said.
Brad Clemenson, a spokesman for Murtha, said the doomed aircraft apparently made at least two other sharp turns during its last minutes -- swerves that are detectable in Flight Explorer's computerized reconstruction of the jet's path.
