If anyone has been watching the olympics (in particular slopestyle) you might of noticed somethign that looks like a drone filming the skiers .
I initially guessed it was one of the cable rig cameras/ spider cam (like the ones they use in stadiums) but after doing abit of looking around online I guess it has been confirmed that they are using both! I suppose the UAV operators have special permission, but still another great example of using drones for good
I found the article on yahoo news and it seems like the operator is from the UK (heliguy)
And for good measure, here is the cable camera (or are the called spider cameras?)
