Nearly 90 drones fell from the sky over Darling Harbour during the Vivid Sydney light show, with footage showing the devices crashing into the water near crowds.⁣ ⁣ Organisers said the malfunction during Monday night’s display was caused by unforeseen technical difficulties, forcing several upcoming shows to be cancelled.⁣ ⁣ UK-based drone company Skymagic said a change in radio frequency triggered the glitch, adding that none of the drones landed outside designated safety zones.⁣ ⁣ #Sydney #VividSydney #Drones #Australia #DarlingHarbour #Technology
