This Sunday marks the 21st anniversary of the September 11th attacks on the World Trade Center and the Pentagon, and the crash of United Airlines Flight 93.
Here are some of the events taking place this weekend to honor the nearly 3,000 lives lost in the tragedy.

The annual event at the site of the World Trade Center off West and Vesey streets takes place this Sunday beginning at 8:40 a.m. The ceremony is expected to end at noon. Vice President Kamala Harris and Second Gentleman Douglas Emhoff are expected to attend.
The ceremony traditionally includes a reading of the victims’ names, as well as moments of silence at the points when the planes struck both towers, when American Airlines Flight 77 struck the Pentagon, when United Airlines Flight 93 crashed near Shanksville, Pennsylvania, and when both towers collapsed.
Access to the plaza is not open to the public during the ceremony. The museum will also be closed to the public throughout the day, open only for the families of 9/11 victims.
At 3 p.m, the Memorial Plaza opens to the public, where people can view the Tribute in Light, which will remain lit until midnight.
Tribute in Light
From dusk to dawn on Sunday night, twin beams symbolizing the World Trade Center towers will light up the city’s skyline.
The beams reach up to four miles in the sky and are positioned into two 48-foot squares, representing the shape and orientation of the Twin Towers.
The tribute can be seen from a 60-mile radius around lower Manhattan.
Various landmarks throughout the city, including the Empire State Building, One World Trade Center, the LIRR East End Gateway at Penn Station and the Kosciuszko Bridge, will also light up in blue that evening to mark the anniversary of the attacks.
