How great was that!! Even a Guineuss world record for the most drones in the sky! Now if you don't use 1200 drones or more in 3D formation, your advert sucks!! Well done to all the people who made this happen ! Can only imagine how much better all the opening ceremonies will be from now on

Bored the shidt out of me
bring on the curling

Yeah fair enough, most of it was boring, but the drones were pretty cool. Advertising agencies around the world will be hating those techs who programmed those drones. "Well the Koreans did it so it can be done, I want that for my ad campaign."
