Need one say more? What an amazing video. Like looking at the earth through the eyes of a bird. Extraordinary.
I doubt you need an explanation about wingsuit flying, but here’s a definition of sorts:
The extreme sport of Wingsuit flying
Wingsuit flying is the sport of flying the human body through the air using a special jumpsuit, called a wingsuit, that shapes the human body into an airfoil which can create lift. The wingsuit creates the airfoil with fabric between the legs and under the arms. A wingsuit may be referred to as a birdman suit or a flying squirrel suit.
A wingsuit flight ends with a parachute opening, so a wingsuit can be flown from any point that provides sufficient altitude to glide through the air, such as skydiving aircraft or BASE jumping exit points, and to allow a parachute to deploy.
… and extreme it certainly is.
