What happened

A thousand-strong swarm of autonomous drones performing at Vivid Sydney festival above Darling Harbour malfunctioned. Many suddenly started flying out of formation and almost 90 fell from the sky into the water below. The failure has been blamed on radio interference.

Reported impact

No one was injured in the incident.

Index analysis

The malfunction highlighted challenges with autonomous aircraft responding safely to failures in urban environments, where changing winds around buildings, interruptions to navigation signals and large numbers of aircraft operating in the same area can make it harder to manage unexpected events.
