My dad imparted his knowledge of RC aircraft on me, eventually getting me to start working towards my PPL.
This guy, who I believe is a cinematographer, uses an HD camera, an iPhone, a large balloon, a parachute and some packing foam to send a little capsule nearly 100,000 feet (yes, that is one-hundred thousand feet, or about 19 miles) into the lower stratosphere, all the while including his children in on the fun. They had the knowledge to put the iPhone in to use as a tracking device.
