Two nights before the 25th anniversary of the September 11 attacks, 2,977 individually lit drones rose over New York Harbor and assembled into the full-scale outlines of the Twin Towers. Each light represented one person killed that day.
The public art installation, titled “2,977 Lights Over New York Harbor,” took place on September 9, 2026. It was free to attend, with clear sightlines from locations including Liberty State Park in New Jersey.
A New Layer on a Familiar Memorial
The installation was developed in close collaboration with victims’ families, survivors, and first responders to mark a milestone anniversary.
The show arrived at the 25th anniversary of attacks that killed 2,977 people across New York, Washington, and Pennsylvania, according to ABC7. Organizers worked directly with family members, survivors, and first responders. The goal was to ensure the display functioned as a respectful memorial rather than a spectacle.
What Witnesses Saw
The drones rose in a spiral formation before locking into fixed three-dimensional coordinates that traced the towers at their original architectural scale.
From the harbor, the fleet climbed in a helix before individual aircraft held position at precise points, forming the rectangular outlines of both towers against the night sky. The drone-formed towers coexisted in the skyline with the annual Tribute in Light, which uses 88 vertical searchlights organized by the Municipal Art Society of New York. Together they created a layered memorial image above the city.
Tribute in Light has run each year since 2002, when it was first erected as a temporary commemoration.
Retired NYPD officer James Smith, whose wife, officer Moira Smith, was killed in the attacks, described the tribute as a reminder of shared loss, according to Reuters.
The People and Organization Behind It
The installation was produced under the New York Foundation for the Arts, with drone work carried out by a company holding 17 Guinness World Records for drone shows.
Professional drone show company Sky Elements operated the 2,977-drone fleet. The company holds at least 17 Guinness World Records for drone shows, according to NDTV Profit.
Creative director and executive producer Addison Mehr oversaw the conceptual and technical realization of the Twin Towers outline at original scale. The installation was a sponsored project of the New York Foundation for the Arts, positioning it within a public-art framework rather than a commercial production.
What the Technology Required
The fleet size was fixed at exactly 2,977 drones, making the number itself the boundary around which all choreography was built.
Each drone occupied a unique point in three-dimensional space to form the towers’ geometry. Algorithmic choreography assigned those coordinates across the full height and footprint of both structures, as DroneXL reported.
Precise positional control was critical: wind or hardware instability at altitude could blur the formation entirely.
What Comes Next
The drone display adds a dynamic, technologically mediated element to New York’s evolving annual practice of 9/11 remembrance.
Tribute in Light started as a temporary gesture and became a permanent ritual over two decades. “2,977 Lights Over New York Harbor” now stands alongside it as evidence that the memorial vocabulary around September 11 continues to grow, shaped each time by the people who lived through it.
