Thursday marks thirteen years since the Twin Towers were turned into rubble in downtown Manhattan on Sept. 11, 2001. For many New Yorkers, it’s more than just a day to remember. The people who lived through the haunting aftermath still feel it.

To honor the anniversary, family members of victims of the 2001 and 1993 attacks have been invited to read names at the National Sept. 11 Memorial plaza, located in the World Trade Center site in Lower Manhattan. Music will be played in the background throughout the program. Live stream footage of the 9/11 anniversary ceremony can be watched here, courtesy of Watch as friends and family honor the nearly 3,000 9/11 heroes in New York City.

The ceremony will pause six times. Twice to mark the times each plane hit the towers, twice to mark the time when each tower fell and twice to observe the moments when the Pentagon was attacked and when Flight 93 crashed in Pennsylvania.

The first moment of silence is scheduled for 8:46 a.m., which marks the time when Flight 11 struck the North Tower. Another moment of silence will be held at 9:03 a.m., when Flight 175 struck the South Tower. At 9:37 there will be a third moment of silence for when Flight 77 struck the Pentagon. The moment of silence at 9:59 a.m. marks when the South Tower fell. Another moment of silence will be held at 10:03 a.m. to observe when Flight 93 crashed. The final moment of silence will occur at 10:28 a.m. to mark the fall of the North Tower.
