U.S. Takes Land For Sept. 11 Memorial

The National Park Service says it will begin taking land for the Flight 93 memorial in western Pennsylvania from property owners because negotiations have proven unsuccessful.

The service says it will condemn about 500 acres still needed for the memorial to be built in time for the 10th anniversary of the 2001 terrorist attacks.

The park service planned to publicly release further details later Thursday.

Flight 93 was traveling from Newark, N.J., to San Francisco when it was diverted by hijackers with the likely goal of crashing it into the White House or Capitol. The official 9/11 Commission report said the hijackers crashed the plane into a Pennsylvania field as passengers tried to wrest control of the cockpit.
