Andy has some other aerial camera systems, wired and heli style. Looking at the model numbers the balloon seems to be the newest kind. A non flammable, non toxic helium balloon that allows for precise and safe steering of the camera indoors or outdoors to a distance of up to 2 km. I can think of infinite uses for this machine.
