During the show in Shanghai, involving nearly 1,000 drones, some of them fell from the sky in the middle of the show. It still remains unclear why the drones began to fall from the sky. According to the media, as a result of the fall, several people sustained injuries and material damage was caused to the building, but then Google rejected this statement. The odd thing is that only a few drones fell from the sky, not all. During the investigation, the law enforcement authorites will try to determine what caused this incident.
