On how many drones were involved, he said:"It was 1,000 across all three sites, so the biggest show we've done like that."Mr O'Mahony added:"Each individual drone has its own little mission loaded onto it and we have then one operator and a back-up operator who triggers that show sequence and sends the drones up. And then in effect we, at the right, very precise time, press the 'go' button and each little drone then flies its own individual mission.
"No one drone knows where the other drones are in the fleet so they're not talking, they're all individual in terms of that movement, they fly the entire routine and luckily come back home at the end of it. When we have the final file, our pilot then uploads that to all the drones but each individual drone has its own separate file attached to it."
