The Flight 93 National Memorial plans to honor victims of the Sept. 11 attacks with a bell-ringing ceremony at the time when United Flight 93 crashed in a western Pennsylvania field, killing 40 passengers and crew.
The National Park Service says that at 10:03 a.m. Wednesday the names of all 33 passengers and seven crew members who died in the crash will be read. Bells will be rung in their memory.
Park rangers and volunteers also will give presentations about Flight 93 and the creation of the memorial park, located in Shanksville, about 75 miles southeast of Pittsburgh.
Flight 93 was traveling from Newark, N.J., to San Francisco on Sept. 11, 2001, when it was hijacked with the likely goal of crashing it into the White House or Capitol.
