Precision is all that mattersTo make hundreds of drones fly in a choreographed formation, precise coding and programming are needed. Among the factors to be considered are airflow generated by drone rotors and safety distance between drones to prevent collision. As drones are reusable and do not produce air and noise pollution, industry experts expect that they could replace nearly half of traditional fireworks displays. Currently, drones are all the rage in South Korea: Some replace fireworks or guest stars in fireworks shows at festivals. On September 24, LG Electronics hosted a drone show, featuring 1,000 drones, to celebrate the launch of its new refrigerator line LG Dios Objet Collection MoodUP.
