An award winning National Geographic documentary was made of this amazing feat of courage, hard-won developed absolute technical skill, a career of planning, years of study & practice, physical strength, focus, perseverence, endurance & so many other qualities developed over a career culminating in this accomplishment, that each aspect could be studied for their development and integration into a whole skill set. Every discipline he displayed therein had to be executed perfectly to achieve this, & he did. Schools have created curricula around aspects of his personal achievement & the work involved in it's accomplishment. Or, knowing nothing about it, you could take 20 seconds to dismiss it out of hand and call him an idiot.
