Interior Secretary Ken Salazar says the government will pay $9.5 million to acquire land so the Flight 93 National Memorial can be built by the 10th anniversary of the Sept. 11 attacks.

Salazar said today the National Park Service has reached agreements with eight landowners and construction is expected to start in November.

Salazar calls the money fair compensation. A department spokeswoman says the agency won't disclose what each owner will receive.

Flight 93 crashed en route from Newark, N.J., to San Francisco. Investigators believe the hijackers' plan was to crash into a Washington target.

The 40 passengers and crew killed have been called heroes for preventing the attack.
