Winter Olympics: Drone display in opening ceremony was pre-recorded

The spectacular sight of 1,218 drones forming the Olympic rings during the opening ceremony of the 2018 Winter Olympics was pre-recorded. Organisers had said that because of "possible freezing weather and strong winds" that part of the event had been "secretly pre-recorded". The International Olympic Committee said it was this footage that was used. "Due to impromptu logistical changes it (drone deployment) did not proceed," said an IOC spokesman. The feat was a Guinness World Record for drones used in a performance.
