Example of a long take, made by a camera operator grabbing a drone mid-flight, and continuing the shot.
The operator has to wear Kevlar to protect themselves from the blades. This one is from Slow Horses, but I've read that they also used in technique in Hacks.
What an awesome shot. I've seen a couple of shots like that before where you just go "ain't no way that's not cg" but then you find out: they found a way.
