"Just winging it" has a completely different meaning for Brandon Mikesell.
The 27-year-old wingsuit flyer from Seattle stars in video released by GoPro on Sunday, and he can be seen flying above -- and sometimes perilously close to -- the mountains near Walenstadt, Switzerland.
In the video, Mikesell soars past jagged cliffs and a pastoral farmhouse, then almost grazes a stand of trees before ultimately zooming down a long trench and pulling his parachute.
In an email to The Huffington Post, Mikesell described himself as "the complete opposite" of an adrenaline addict.
"The same thing that is running through most people's head when standing at the edge of a cliff is what's running through my head," he said. "The nervous shakes, butterflies in my stomach, the paralyzing feeling in my body, and extreme sweating."
But it's all worthwhile once he takes the plunge.
"As soon as I step off that cliff I feel absolutely nothing! It is extremely peaceful, and all my worries and fears go away. My training has taken over and I am not feeling or thinking about anything as I fly through the air. I am living in the moment and that's what it is all about for me."
Despite his terrifying choice of sport, Mikesell previously said his greatest fear is actually "everyone finding out that I have a major stuttering problem."
He told TomorroWoman he felt like the only person who had a stuttering problem when he was growing up.
"The first time I ran into a fellow stutterer was when I was 22 years old," he said. "I really want people to know that they aren’t alone. I want to meet and help as many people as I can who might be going through a rough time, or even just need a little positive nudge. I hope I can pay it forward and motivate or inspire as many people as I can."
Mikesell added that he's completed over a thousand jumps before venturing into more technical flights like the one featured in this video, so, yeah, don't try this at home.
