About 100 drones with flashing blue lights, lost control and crashed into a building during a show in Southwestern China's Chongqing Municipality on Monday night, the state media reported.
They moved slowly toward a building, with some crashing into it and others directly dropping from the air and falling into the river. Several people screamed that they could not control the drones.
A person familiar with the matter later disclosed that a crash in the mainframe control led to the incident. Although there were no injuries, the incident resulted in huge economic losses for the show designers.
