Gov. Charlie Baker once again led the invitation-only event with help from other state and local leaders.

After the American flag was lowered to half-staff to honor those who died, there was a moment of silence at 8:46 a.m. to mark the exact time the first plane crashed in Manhattan.

Then, the names of all 206 people with ties to Massachusetts who were killed that day were read aloud.

SWEENEY AWARD

A short time later, the Madeline Sweeney Award for Bravery was presented to Gardner resident Annette Szivos, who saved a man from drowning.

Sweeney was a flight attendant on American Airlines Flight 11, the first plane to leave Logan Airport and crash into one of the World Trade Center towers in lower Manhattan. She called a ground supervisor and relayed information about the hijackers to investigators.

The commemoration ended around 11 a.m. with a wreath laying ceremony led by acting Boston Mayor Kim Janey.

CARE PACKAGES FOR MILITARY

At 9 a.m. on the Rose Kennedy Greenway in Boston, volunteers joined 9/11 and military families to put together 750 care packages for local troops and veterans in need. They’ll also made 75 “kindness blankets.” The event was organized by the Massachusetts Military Heroes Fund and Project 351.

USS CONSTITUTION

At 11 a.m. at the Charlestown Navy Yard, the USS Constitution went for a trip around Boston Harbor with Medal of Honor recipients on board.

The public was invited to come to the USS Constitution Museum to help built 1,000 care pouches for new sailors and Coast Guardsmen.
