The sky as a canvas: a visual guide to the artistry and science of drone shows

this was a fascinating and really well done overview of those amazeballs drone shows.

this actually answered a number of questions that i had rolling around in the back of my mind on the logistics and transitions fronts. notably yes, the drone launch area more or less determines the overall size of the drone display. yes, they have better than standard GPS operation. (they use real time kinematic GPS)
