SHANKSVILLE, Pa. (AP) - Hundreds of family members and friends of the 40 passengers and crew killed aboard United Flight 93 are gathering for a second day at the newly dedicated national park that marks the site where the hijacked jet crashed during the Sept. 11, 2001 terrorist attacks.
Sunday's memorial service joins those in New York City and Washington, D.C., where other hijacked jets crashed into both towers of the World Trade Center and the Pentagon. Vice President Joe Biden and former presidents Bill Clinton and George W. Bush were on hand Saturday to christen the Flight 93 Memorial near Shanksville, about 60 miles southeast of Pittsburgh. President Barack Obama is expected to visit the Flight 93 site on Sunday, but the precise time of his arrival has not been announced.
