As a tribute to the victims of Covid-19, 40 drones lit up the night sky in Madrid on the 26th of June in a special display. The drones created various shapes during the 10-minute routine including a flying dove, a house and a parent and child walking. The display also honoured the emergency workers fighting at the frontlines of the pandemic and showed various flags of the countries badly hit by Covid-19. Using LEDs and a prepared software, they also spelt out messages. The exact location of the show was kept a secret to avoid crowds.
