Flight 93 exhibit opens in Pennsylvania

HARRISBURG, Pa. -- Tributes left in the field where United Flight 93 crashed Sept. 11 were put on display Wednesday at the State Museum of Pennsylvania.

Officials assembled "Flight 93 Remembered" with help from the Somerset County Historical and Genealogical Society. The display will run through Oct. 2.

Forty people were killed when the airplane crashed in Somerset County 80 miles east of Pittsburgh. Officials believe the plane was heading for a target in Washington, D.C., when passengers fought against four hijackers.

"Flight 93 Remembered" will be on display through Oct. 2.
