During 2010~2013, I launched a series of payloads connected to high altitude ballons. All of these were connected through a home brew radio transmission and GPS so I could chase them in a car (and once, a speed-boat!). All missions ended in succesful recovery. One was for a TEDx talk, one was for dutch national television.
All of these had (video) cameras (and once, a Polaroid camera) attached to snap pictures from this high altitude.
