Vivid Sydney cancels shows after 89 drones plunge into Darling Harbour

89 Skymagic drones fell into Darling Harbour at Vivid Sydney after RF interference triggered geofence failsafes; 4 shows cancelled. Possibly deliberate RF jamming surfaces as a critical risk for drone fleets, making spectrum security a UAV deployment requirement.
