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.


I’ve always questioned how they co-ordinate these things to prevent situations like this.
I guess the answer is they don’t?
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.
