It's well off-season, but I find the details behind the Tour de France filming operations to be fascinating:

During a race stage, camera pilots juggle six different radio frequencies, continuously communicating with each other, the camera operators, air traffic control, France TV, technicians and sportscasters. Over flat countryside, pilots not only have to maintain correct position but watch out for towers—especially high-voltage power lines. In the mountains they contend with unpredictable winds and hot temperatures that sap engine/rotor performance.

So... only a metric crapton small handful of things to keep track of simultaneously. Got it. Sounds totally reasonable. More @ Ars Technica →
