Gear: Nikon Keymission 360

We've all seen those cool flying ­videos ­captured with a camera installed on the wing. But most only show the pilot's ­reactions to the outside world. Imagine if you could turn the camera view in any direction in flight and see what the pilot does. For just under $500, Nikon's ­KeyMission 360 can spin that wing camera around 360 ­degrees. It offers ultra-slow-motion and time-lapsed ­photography, employing Hollywood-like effects, so sky warriors — or scuba divers down to 100 feet — can create 360-degree videos in stunning 4K HD detail.

With both Bluetooth and Wi-Fi already standard, a pilot or diver needs only to bring along a smartphone to control the action. So experiment and explore, but you might want someone in the right seat of the airplane to manage the camera while you do the flying.
