This is Gary Connery. He is a British skydiver and stuntman. He has acted as a stunt double in several movies, and has completed over 1.000 jumps in his lifetime.
In May of 2012, Gary was the first person to ever skydive without a parachute (and survive). Using a wingsuit, Gary jumped from a helicopter hovering some 2400 feet off the ground. He then swooped down to land on a landing strip made up of 18,600 cardboard boxes. One viewer/fellow wingsuit jumper called it the "greatest stunt ever performed".
