First, a quick word of warning: if you're like me and have a mild to major fear of heights, this one might be a tad bit "too real to deal." With that cautionary advice out of the way, I'd recommend setting this one to high-definition if possible and going full-screen to feel the extreme thrill of this B.A.S.E. jump above. (And possibly have some motion-sickness medicine ready.)
Is it over? Can I look now? All kidding aside, the first-person perspective climb and jump features extreme athlete Erik Roner, who was previously highlighted on here for a variation of "Mary Poppins" and her classic umbrella flight, and was posted by GoPro who write:
Erik Roner takes us to the top of a precarious antenna before B.A.S.E. jumping off.
