SHANKSVILLE - The 40 passengers and crew members of a plane that crashed in western Pennsylvania after it was hijacked during the September 11 terror attacks have been honored with a reading of names and tolling of bells.

Hundreds have been taking part in the annual service at the Flight 93 National Memorial in Shanksville as ceremonies have also been taking place Sunday in New York and Washington, D.C.

For the first time, the Shanksville ceremony is being held outside the visitor center that opened last year rather than at the granite mall that runs along the crash site.

The United Airlines flight was heading from Newark, New Jersey to San Francisco when it crashed after passengers and crew fought the terrorists for control of the plane.
