Hristo Botev - National Hero Drone Show 

The face of Hristo Botev rose 120 m above the Vrachan Balkan. To form the face of Hristo Botev, each of the 200 drones receives a signal from space via navigation satellites flying in low orbit around the Earth. Our team spent 4 months to make this unique drone show in Bulgaria. We thank the city of Vratsa for the provided terrain.
