So cool
In the night sky, a troupe of colorful small drones danced above a mesmerized audience at the 4,000-foot airstrip. The drones hovered and glowed in careful choreography, possibly mistaken for seasonal fireworks. Four drones, equipped with 3,000-lumen lights, flew autonomously; the time-lapse camera caught the images that appear as a flying trout when played in a loop.
