When man created GoPro cameras, this is what he intended them to be used for. This video shows the amazing Black Diamond Jet Team in training—and if you're scared of flying, it might be best not to watch it.

Two things strike me. First, the banked turns close to the ground look incredibly low. I can only begin to imagine how exhilarating that must be. Second, when the team fly in formation, the amount of buffeting which causes the planes to move relative to each other is quite, quite terrifying. These guys have massive balls. Respect.
