Eight years after the Sept. 11 attacks, the U.S. government and landowners in Somerset County have reached an agreement that will allow the building of a memorial  to the passengers and crew of  hijacked Flight 93 that crashed into the fields of rural Pennsylvania. SHANKSVILLE

Interior Secretary Ken Salazar says the memorial will cost about $20 million, which includes $9.5 million for the land.

“The fields of western Pennsylvania, where the heroes of Flight 93 perished, are hallowed ground for a grateful nation,” Salazar said.

“We have reached this important milestone in properly honoring the courage and sacrifice of the men and women who gave their lives that day,” he said. “The Flight 93 Memorial will soon stand in their honor.”

The National Park Service signed agreements with eight landowners and expects construction to begin after groundbreaking in November with an eye to completing the memorial by Sept. 11, 2011.
