9/11 anniversary ceremonies

Ceremonies will be held around San Diego tomorrow to commemorate the seventh anniversary of the Sept. 11, 2001, terrorism attacks and pay tribute to the 2,974 people killed.

A “World Memorial’’ salute to the victims of the terrorism attacks, their families and public safety responders will be held from 10 a.m. to 3 p.m. at the Civic Center Concourse in downtown San Diego.

At the event, there will be pieces of steel from the World Trade Center on display, missing person flyers, artwork, stories by victims, memorial emergency vehicles and a noon ceremony.

The University of San Diego will remember the terrorism strikes during its annual 12:15 p.m. Mass of the Holy Spirit service at the Immaculata Church on the campus of the Catholic college.

Aboard the USS Midway Aircraft Carrier Museum at 2 p.m., officials will read the names of the victims of the attack. The event, sponsored by FDNY Retirees of California, also includes a 21-gun salute and a San Diego Police Department helicopter flyover.

At 5 p.m., FDNY Retirees of California will hold a dinner reception at the Old Firehouse Museum in Little Italy.

Hundreds will later march through San Diego’s Balboa Park during the third annual “Freedom Walk’’ to reflect on the lives lost during the terrorist attacks. The event, sponsored by Operation Homefront, is scheduled to begin at 6 p.m. with the release of 100 doves.

The walk will end with an 8 p.m. candlelight vigil, featuring speeches by the sister of fallen New York City firefighter David Weiss and former Fire Department New York Lt. Joe Torrillo, who lived despite being presumed dead when the World Trade Center collapsed.

On Sept. 11, 2001, hijackers slammed two airliners into the World Trade Center in New York. Both buildings later collapsed with hundreds trapped inside. A third plane slammed into the Pentagon in Washington, D.C., and a fourth that was believed to be bound for a target in Washington, D.C., crashed in a Pennsylvania field.
