回复13楼:Fourth of July celebrations in some cities will be a lot quieter this year, at least when it comes to action in the sky. In several areas across the country, independence won't be commemorated with booming fireworks displays, but with the quiet buzzing of technicolor drones.
First arriving on the scene about a decade ago, drone light shows have rapidly increased in popularity over recent years, even appearing at the halftime show of last year's Super Bowl. It's a dazzling use of technology that gives viewers a futuristic show unlike anything else.
