In short:
Vivid Sydney festival’s drone show has been cancelled for now after a technical malfunction on Monday night.
The drone show’s operator says a change in radio frequency caused 89 drones to fall into the harbour around Cockle Bay.
What’s next?
A Vivid Sydney spokesperson says Tuesday and Wednesday’s drone shows will not go ahead, with no decision yet made for Sunday’s show.


It’s possibly cheaper to just buy new drones instead of making software that only has a chance of them returning home without rtk GPS.
The general rule with drones is it’s safer for them to fall out of the sky when something goes wrong.
