I Was Once Crazy Enough To Jump Out Of Airplanes, But This Is Extreme! [VIDEO]

As a former Army Parachute Rigger I've got several jumps under my belt. That activity alone might seem crazy to some people, but at least WE HAD PARACHUTES ON! The people in this video are climbing to stupid heights and then they walk on the edge and sometimes hang over it. 

Oh and, they do this without safety equipment!

It's a no brainer to say "Don't try this at home."
