A Vivid Sydney light show was cancelled Monday night after a technical malfunction caused nearly 90 drones to fall into Darling Harbour.
The incident highlights the potential safety risks and technical vulnerabilities associated with large-scale automated aerial displays in densely populated urban areas.
The drones were operated by a UK-based company. According to the operator, the malfunction was caused by a change in radio frequency [1]. The failure led to the drones losing stability and dropping from the sky into the water [2].
Reports on the exact number of aircraft involved vary slightly. One source said 89 drones fell [1], while another reported the number as 90 [3]. A third report described the total as almost 90 [4].
Organisers of the Vivid Sydney festival halted the performance immediately following the glitch [1]. The drones crashed into the harbour, where they remained until recovery efforts could begin [2]. No injuries were reported in the immediate aftermath of the crash.
Darling Harbour served as the backdrop for the event, which is a central part of the annual Vivid Sydney festival [4]. The festival is known for its expansive use of light and technology to transform the city's landscape [3].
The UK company responsible for the fleet is working with organisers to determine the full extent of the radio frequency interference. The company said the technical glitch was the primary driver of the failure [1].

This failure underscores the fragility of swarm drone technology when exposed to urban radio frequency interference. As cities increasingly rely on these displays for tourism and entertainment, the incident may prompt stricter regulatory oversight and more rigorous signal-testing requirements for international operators working in Australian airspace.
