Toward 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 Lennon’s “Imagine,” which was reworked by Hans Zimmer for the Olympics, played across the stadium.

We’ve seen displays like this before. At Super Bowl LI in 2017, a pre-taped segment featuring 300 Intel drones forming the US flag punctuated Lady Gaga’s halftime performance. Technically, the drone show that occurred above Tokyo isn’t the biggest ever. As of earlier this year, that distinction belongs to a 3,281-display Hyundai-owned car brand Genesis put on in Shanghai, China. But even with fewer drones involved, the Tokyo drone show was still impressive.
