A 7-year-old boy was injured after the drones that were part of a planned 15-minute choreographed aerial show over a Christmas-themed market for families went rogue and started to collide and fall over the crowd.

Police in Singapore have taken an extraordinary step to ensure people are following social distancing rules. In a 3 1/2-month trial, police have used 22-pound pilotless drones, developed by Israel’s Airobotics, as a way to enforce social distancing and contain the spread of COVID-19, according to Reuters. Airobotics CEO Ran Krauss told Reuters the company is simply helping police maintain normal operations, specifically related to COVID-19. “The pandemic created a situation where it might be difficult for police to maintain,” Krauss said. The trial continues on in the social distancing aspect, according to Airobotics, and Krauss said the company is in talks with other cities to deploy drones.
