SEEN & HEARD

摘要

The first Paris Drone Festival took over the Champs-Elysees Sept. 4. In a cage topped by a 100-meter-long net, drones competed in races, going as fast as 100 kilometers per hour. Behind the security gates, 150,000 watched, while another 30,000 viewed events via a live stream. Its mission was to demonstrate uses of drones and educate the public about issues around safety and security.
