Drones drop from sky during performance

A video of a number of drones falling from the sky during a performance in Xi'an, Shaanxi province, went viral online, embarrassing a new Guinness World Record winner, Ehang Egret, a drone-maker in Guangdong province.

The drones were supposed to stage a light show on Tuesday called Xi'an in Spring, highlighting the opening of the 2018 Xi'an City Wall Culture Festival. The show included 1,374 drones that created formations such as the city wall and the Chinese characters of Xi'an.

The drones on the left side of the formation were disorganized and out of sync when they flew over the city wall, and some fell rather than landed as planned.
