Union City's ceremony was scheduled at 10 a.m. to remember passengers on board United Airlines Flight 93, the fourth hijacked plane that did not hit its intended target, crashing instead in western Pennsylvania when the passengers tried to overcome the hijackers.
That flight was headed from Newark, New Jersey, to San Francisco International Airport when it crashed. The ceremony was held at the Union City memorial to the 33 passengers on board, created by a Hayward former marine and dedicated in December 2007.
The Livermore-Pleasanton Fire Department also planned a memorial at about the same time at Fire Station Number One at 3560 Nevada St.
