Tokyo Olympics opening ceremony included a light display with 1,800 drones

There may not have been any fans in the Olympic Stadium, but Japan still found a way to put on a show for the opening of the 2020 Summer Games. The host country charmed early with the parade of nations, which featured an orchestrated video game soundtrack, and then showed off the type of creativity it's known for with a performance involving the Olympic pictograms. But Tokyo saved the biggest spectacle for last. Towards the end of the ceremony, a fleet of 1,824 drones took to the skies above the Olympic Stadium. Initially arrayed in the symbol of the 2020 Games, they then took on the shape of the Earth before a rendition of John Lenon's "Imagine," which was reworked by Hans Zimmer for the Olympics, played across the stadium.
